Experience and expertise
you can rely on
FIBRO Quality Assurance
FIBRO is renowned for its quality world-wide. This high quality is achieved
through our dedication and commitment to Quality Assurance.
FIBRO testing starts on the raw material and continues right through
production to the completed product. The test facilities themselves are
also subject to stringent continuous testing. Only by setting itself such
stringent standards can a company support its customers long term in
safety, cost-effectiveness and quality.
Tests during production
Precision shape and contour testing equipment is used directly in
production. This ensures early confirmation of the quality of the product.
The shape testing equipment tests for qualities such as roundness,
concentricity, straightness and rectangularity.
FIBRO state of the art technology provides 3D visualisation of
concentricity, coaxiality and cylindricity.
Materials testing - raw materials to
specification
The FIBRO laboratories carry out microscopic investigation of the raw
materials, including enlargement to 2,500 times natural size.
Spectral analysis determines whether the material is correct in terms of
chemical composition.
Hardening – hardness testing
All the process parameters in the hardening process in our own hardening
shop are recorded and documented.
Hardness testing is used to monitor the results of the hardening process
on every batch.

The FIBRO cam unit program offers matching system solutions for the widest range of applications.
From the use in progressive punching tools with the smallest dimensions up to the demanding use in large tools.
From the use in tools with small piece numbers up to premium applications in the manufacture of bodywork parts with
the highest requirements in terms of precision, lifetime and process force transmission, our cam unit program offers
the matching solution to your application. The fault-free operation is guaranteed by FIBRO over the guaranteed,
nominal lifetime. The design of the cam units, in the course of the tool construction, is indispensable in this regard.
Operating conditions of the tool, as well as the expected environmental influences, must be taken into account to the
best extent possible. Using a precise and conscientious design, it is possible to achieve a lifetime which extends far
beyond the guaranteed stroke rate.
The desired lifetime can only be achieved by using the cam units as intended. An overloading of the cam units will
reduce the number of strokes of the cam unit and can, in the extreme case, lead to the immediate failure of the cam
unit during the initial strokes.
The operational reliability of FIBRO cam units is demonstrated by the guaranteed number of strokes. The size of the
working force, the position of the center of the force on the working surface and the sequence of the introduction of
the force, all have an effect on the system. All performance specifications were calculated using factors known to us
at the time of printing. Changed operation conditions can influence the lifetime of the cam unit and must be taken into
account separately in consultation with the operator.
FIBRO supports you competently throughout the entire process chain: Starting with the selection of a suitable cam
unit for your application, to the correct design, up to the delivery of the cam unit to the assembly, FIBRO is by your
side when you have questions. After the completion of the engineering and assembly phase, FIBRO's after-sales
support also provides you with professional support for your needs. Take advantage of our experience as a standard
system supplier for toolmaking and customise your tools with our products to your specific applications in the most
optimal way.

DESIGN TOOL CONNECTION
The size of the maximum force transferable by the cam unit is significantly influenced by the type of installation
chosen. A technically correct selection of the installation type must be considered analogue to the cam unit design.
The working force can be transmitted via the shoulder of the cam base on FIBRO cam units, alternatively via concealed fitting wedges on the cam base support. The shouldered installation allows maximum load values to be transferred, while a compact mounting space can be realized by installing via the concealed seating wedges. The reduced
load values must be observed when installing via the feather keys.
The manufacture of the cam unit interface in the tool can be optimised by means of simple constructional solutions
and cost-effectively, without loss of performance.
Force transmission via shoulder
The maximum power values of the cam unit are achieved by the shouldering of the cam base in the nominal shoulder
height (see catalogue specifications). It is not necessary to shoulder the die over the entire height of the cam base.
In the following, three possible versions of the shouldering of the cam base in the die are shown, the designs 2 + 3
thereof are preferred since production is optimised.

Force transmission via feather key
In the case of lower requirements on the transmission of force, the cam unit can be installed in the tool by means of
bracing via the key so that it is optimised to the installation space. For the mechanical machining of the feather key
groove, in this case a distance from the groove geometry to the possible interference geometries in the die cast of at
least 140 mm must be observed in order to avoid a collision of the milling spindle.

CAM UNIT DESIGN
The operating reliability is demonstrated independently of the operating mode as follows:
1. Evaluation of the calculated operating force
2. Evaluation of the arithmetical centre of force and formation of the substitute force
3. Comparison of the substitute force with permissible force
The operating force is generated by the tools mounted on the cam during the engagement in the sheet metal.
When determining the operating forces, the following operating modes are distinguished:
a) Cutting
b) Punching
c) Forming
d) Operations with additional stripper
a) Cutting
During cutting, the operating force is created by overcoming the shear strength of the machined sheet metal part.
The force is calculated using the formula:
FS = l 3 s 3 tT [1]
Cutting length [l] and sheet thickness [s] are taken from the method plan, the shear strength [t] from material tables. If
there are no values for the shear strength, this can be approximately determined from the tensile strength. For ductile
materials, this amounts to between 60 and 90% of the tensile strength.
In general, the maximum value of the possible characteristic range of the sheet material must be used as a basis for
the calculation because the steel grades are produced and delivered within the specified range. Thus, the characteristic values of the processed sheets can assume the highest permissible characteristic values and thus also the
highest possible loads on the tool components can be applied.
For evaluating the cam unit stability, the centre of force applied by the cutting is determined and compared with the
force diagram of the desired cam unit. The centre of force of the cutting is determined by means of the centre of mass
of the cutting line. For this purpose, complex, free-shaped sections can be dissected into a sufficiently precisely segmented substitute contour with known segment focal points (see Fig. 5)
Subject to alterations 27
Figure 5: Cutting contour original and approximated
The total centre of force is determined from the individual segments of the line:
x value:
xC = (x1 3 l1 + x2 3 l2 + xn 3 ln) / (l1 + l2 + l3) [2]
y value:
yC = (y1 3 l1 + y2 3 l2 + yn 3 ln) / (l1 + l2 + l3) [3]
The following boundary conditions apply to the calculation model:
In this determination of the centre of force, a uniform trim steel engagement is assumed. A non-uniform trim steel engagement determines both the change in the cutting force FT as well as the centre of the force CF over the cutting
line tT.
Force-reducing measures such as, for example, the targeted manipulation of the cutting line are not taken into account in this consideration. The modification of the strength values by a cold work hardening of the material in preliminary forming operations is likewise not taken into account in this consideration. It applies in particular to modern,
high-strength materials for vehicle structural components (e.g. in dual phase steels) and depends on the material
as well as on the degree of metal forming. Cold work hardening effects must be taken into account in the individual
case in the design of the cam unit. If a stripper is used on the cam unit, the loading by the stripper must be taken into
account accordingly (see section d).
ENGINEERING
CAM UNIT DESIGN
28 Subject to alterations
b) Punching
Punching is a special form of cutting. The determination of the operating force thus follows a similar scheme, although some important particulars have to be considered.
The determination of the force is performed analogous to the calculation of the force during cutting. In the case of
punching operations, several punches are often arranged on a cam unit. In this case, the force introduced by each
punch must be determined as well as the sum of all individual forces.
FPn = ln 3 s 3 TT [4]
FPtotal = FP1 + FP2 + FPn [5]
As a second step, the determination of the centre of the force is carried out analogously to the design during cutting.
In contrast to simple cutting, the position of each individual punch and the position of centre of mass of the sum of the
individual cells must be examined during punching and compared with the force diagram. This is necessary, since
during punching onto a mould surface, each punch engages with a very high probability at a different point in time,
and the load in the cam unit is also introduced in a steplike manner.
The centres of the force are calculated as follows:
Figure 6: Hole sample
ENGINEERING
CAM UNIT DESIGN
Subject to alterations 29
ENGINEERING
CAM UNIT DESIGN
P1 (round hole) > centre of force in the centre
P2 (slot) > centre of force in the centre
P3 (square hole) > centre of force in the centre
P4 (shaped hole) > determination of the centre by calculating the line centre
In the determination of the total centre of the force of a punching field, the individual cutting lengths of each punch are
replaced by the punching forces. The total centre point of the punch field can thus be determined from the individual
centre positions:
x value:
xC = (x1 3 FP1 + x2 3 FP2 + xn 3 FPn) / (FP1 + FP2 + FPn) [6]
y value:
yC = (y1 3 FP1 + y2 3 FP2 + yn 3 FPn) / (FP1 + FP2 + FPn) [7]
Boundary conditions of this calculation model:
In the consideration, a uniform punch engagement of each individual punch is assumed, which is the exception due
to the component shape. Tilt and bending of the mould surfaces cause a delayed plunging of the punches. The cutting force reduction by these geometric effects is not taken into account in this calculation model.
The load is changed by the use of a stripper. This must be taken into account in the cam design (see section d)
c) Forming
The term "forming" includes all operations that cause a ductile, permanent form change of the component. The following work operations belong to the forming operating mode:
- Chamfering
- Adjustment
- Postforming
- Drawing
The force required for moulding depends on the shape and the material characteristics. Forming operations on vehicle components are usually complex due to the free form of the components and produce a multi-axial state of stress.
The determination of the forces required for this purpose is only possible with difficulty or only with a disproportionate
effort. The moulding forces occurring can usually be determined by a drawing simulation. Hard die spotting ("drive to
final pressure" / "run against block") with the cam unit is to be avoided if possible. By insufficient coordination of this
operation, forces can be introduced into the cam, which exceed the permissible maximum of the allowed operating
load by a multiple. Thereby, an immediate failure of the cam unit is possible.
30 Subject to alterations
d) Operations with additional stripper
An additional force is introduced into the cam by the use of a stripper resp. cam pad. It is to be taken into account
accordingly.
Strippers are used as a stripper plate or as an elastomer / pop-on stripper. The calculation of the centre of force of
both variants differs.

ENGINEERING
CAM UNIT DESIGN
d.1) Elastomer-/Pop-on stripper
Elastomer / Pop-on strippers are extremely compact stripper units, which are directly attached to the supporting
plate of a punch. By this arrangement, the centre of mass of an elastomer / pop-on stripper element is centred on the
centre axis of the punch.
The total operating force corresponds to the sum of the cutting and stripping force. The centre of mass is then calculated analogous to punching.
d.2) Stripper plate
The centre of the force produced by the stripper plates, in contrast to elastomer / pop-on strippers, is not coincident
with the centre of mass force of the working operation. If working with a stripping plate, both the total centre of force
of the working operation + stripper plate as well as the centre of force of the stripping plate alone must be compared
with the permissible operating force of the cam. This is due to the fact that the load of the stripper plate continues to
be present after the fall of the operating force, for example, after punching through the sheet, until the stripper springs
are released while opening the die.

PROOF OF LIFETIME
The lifetime test is carried out by comparing the existing operating force with the maximum operating force permitted
for the guaranteed lifetime. This results in the statement whether or not the cam unit with the introduced force reaches
the guaranteed lifetime.
Cutting
The calculated operating force in the determined centre of the force is compared with the permissible operating force
from the force diagram of the desired cam unit. The cam unit maintains the guaranteed lifetime if
FB % Fzul [12]
Punching
When punching, each individual punch Pn must be compared with its centre of mass Cn, as well as the sum of all
punches with the total centre of the force point, with the force diagram of the desired cam unit. The cam unit maintains
the guaranteed lifetime if
FBn % Fzul [13]
and
FBtotal % Fzul [14]
Forming
The operating force determined from the drawing simulation and applied at the centre of the force point is compared
with the permissible operating force from the corresponding force diagram. The cam unit maintains the guaranteed
lifetime if
FB % Fzul [15]
Stripper with cam stripper plate
When a cam stripper plate is used, the sum of the operating force + stripping force, with its associated centre of the
force point, as well as the stripping load alone, must be compared with its centre of the force point with the force
diagram. The cam unit maintains the guaranteed lifetime if
FA + FB % Fzul [16]
and
FA % Fzul [17]
General instructions
- The force specifications of the individual force diagram sectors must never be added.
- The substitute force with the corresponding centre of the force point must always be formed in accordance
with the preceding descriptions and these must be compared with the force diagram.
- The specifications in the force diagram correspond to the punctually introduced substitute loads and are not
surface pressure specifications!
General notes on permissible operating force
As a matter of principle, the transverse loads acting on the cam unit are to be absorbed by design measures in the
tool. Uncompensated transverse loads can have a massively negative effect on the cam unit lifetime.

RETRACTION AND RETURN FORCE
Determined by the tension conditions and resulting elastic deformations in the machined sheet metal, cutting and
forming components stick after the machining process when the bottom dead centre is reached. Accordingly, a stripping force is required to pull the tools out of the sheet into the initial position. For the design of tools, an approximate
calculation of the stripping forces, based on experience values, is sufficiently accurate. The stripping force is calculated as a percentage of the working force.
For cutting operations, this amounts to:
FA = 0.07 3 FT [valid for open cutting contours] [18]
FA = 0.10 3 FT [valid for closed cutting contours] [19]
In the case of forming operations, the stripping forces vary to a greater degree. When determining the stripping forces
during forming operations, the instructions of the tool manufacturers or operators must be observed.
Cam units have a system-related retraction capability. This can be used to overcome the necessary stripping force.
If the retraction capacity of the cam unit is higher than the necessary stripping force, no tool-specific actions need to
be taken to return the die components to the initial position. In this case, the cam unit can work directly through the
main pad of the die.
FR > FA [20]
If the retraction capacity of the cam unit is less than the tool- or process-specific stripping force, then constructional
measures need to be provided, such as the use of a cam stripper.
FR < FA [21]
The retraction force specifications of all FIBRO cam units refer to the working direction of the cam unit, thus, a conversion is not necessary.
If an aerial cam unit remains in its bottom dead centre after the working operation, considerable damage to the cam
unit and die is to be expected due to collision of die components while opening it.
In contrast, if a die mounted cam remains in its bottom dead centre after the working operation, then no profound
damage is to be expected in the event that the cam does not operate through the main pad. As a rule, the die mechanism in this case is not able to remove the blank out of the die, which stops the movement of the machine by means
of the mechanisation sensor system.
If the die components of a die mounted cam also operate through the main pad, similar damage to the cam and die
as in the case of an aerial cam unit is to be expected.
Please note that for this reason, the mechanical retraction clamps must not be removed without consulting with
FIBRO.

The determined force values are compared with the performance data of the selected cam unit. For this work operation, an aerial cam unit of the 2016.24. series with a working width of 260 mm is to be used. The cam unit has the
following performance data:
max. working force (shouldered installation): 737 kN
max. working force (installation with feather key):359 kN
Retraction force: 36.4 kN
The total centre of force of the cam cut is on the quadrant of the force diagram with 737 kN permissible load (shouldered) or 320 kN permissible load (installed with feather key). The cam unit can therefore be installed with the given
cutting contour and the applied process parameters both with the force relief via a shoulder on the rear side of the
cam base as well as via the feather key inserted into the cam base supporting surface in the die:

Figure 14: Hole pattern with individual centre of mass
The determined force values are compared with the performance data of the selected cam unit. For this work operation, preferably, a compact aerial cam unit of the 2016.24. series is to be used.
Due to the maximum distance of about 72.6 mm of the centre of mass of the holes, an attempt is made to use a cam
unit with a width of 110 mm and a multi-punch retainer plate.
The selected cam unit has the following performance data:
max. working force (shouldered installation): 372 kN
max. working force (installation with feather key): 93 kN
Retraction force: 5.8 kN
The total centre of the force of the hole pattern is on the quadrant of the force diagram with 372 kN permissible load
(shouldered) or 80 kN permissible load (installed with feather key). Therefore, the process forces on the cam should
absolutely be absorbed by a shoulder on the back of the cam base for the given hole pattern and its process parameters:
Fpermissible feather key < FP < Fpermissible shoulder
80 kN < 173 kN < 372 kN
The individual centres of the force of each punch lie on quadrants of the force diagram in each case with a higher
permissible load than the present operating force. A stepped punching caused by the partial shape thus does not
cause any unacceptable overloads on the cam unit. In the following, only the forces with the force diagrams installation type "shouldered" are compared:
Punch P1:
30.1 kN < 91 kN
Punch P2:
34.3 kN < 164 kN
Punch P3:
52 kN < 164 kN
Punch P4:
56.6kN < 164kN

Figure 15: Hole pattern with force diagram
The constructional retraction force of the cam is not sufficient to move the slider back into the initial position while the
press opens; the return force of the cam is less than the process-induced stripping force:
FR < FA
5 kN < 17.3 kN
Die specific actions must be taken in order to ensure that the slider can be returned.
In this case, a cam stripper is used.
b) with gas-spring-operated cam stripper
The cam from point a) is equipped with a gas-spring-operated cam stripper to increase the retraction force. It has
to be operated by two or three compact gas springs of the POWERLINE series. According to the design, approx.
12 kN retraction force is missing for a smooth process. Springs of the POWERLINE series with a cylinder diameter
of 38 mm have an initial force of 5 kN. For the present case, three springs are thus required for the actuation of the
cam pad. The springs are mounted using a square mounting flange. The additional installation space required for
this is to be taken into account when selecting the cam unit. As a result of the flange dimensions, the width of the
slider working surface must be at least 147 mm. Accordingly, the next largest cam unit width is selected with 150 mm.
With approx. 8 kN, this cam unit has a greater retraction capacity than the originally selected cam unit with a width
of 110 mm. With this cam unit and the selected gas springs, two pieces are sufficient to actuate the cam stripper. In
order to be able to accommodate the guide, retaining and safety elements on the cam unit work surface, to obtain a
good distribution of the force introduction, and to realise a compact overall space, the springs are arranged diagonally on the working surface (compare illustration).

Constructive actions can reduce or compensate operating and secondary loads (e.g. transverse forces). These actions may have effects on the quality of the press part or the manufacturing process. Therefore they have to be coordinated with the operator of the die.
a) Modified trim steel geometry
In the case of a simultaneous trim steel engagement over the entire cutting length, the cutting work is performed over
the path of the sheet thickness. The cutting work is calculated from:
WT = FT 3 t
If the trim steel geometry is designed in the form of a shear, a roof or a wave, the working path is extended analogous
to the selected trim steel shape. The performed cutting work WT remains unchanged in its size, therefore the necessary cutting force FT becomes lower.
Figure 18: Trim steel with parallel grinding Figure 19: Trim steel with top grinding
Figure 20: Trim steel with scissors grinding Figure 21: Trim steel with wave grinding
The cutting force can be reduced up to 50% by means of a cutting force reducing design. Due to the geometrically
altered design of the trim steels the centre of the force may also vary during the cutting process. A quantitative statement about the centre of the force progression is difficult to determine with trim steels shaped in this way. Due to cam
load it’s recommened to design the force-optimised trim steels symmetric.
For aluminium press parts, these cutting force reducing actions are not recommended. They can cause uncontrollable, inadmissible process fluctuations here.

b) Absorption of transverse forces
Transverse forces cause additional loads on the cam unit components. They add up vectorially to the operating force
in the cam direction and thus have a significant influence on the cam unit lifetime. Therefore transverse forces must
be compensated by constructive measures in the die in order to prevent system overload. The absorption of the
transverse force is preferably performed parallel to the working engagement at the same height.
Figure 22: Absorption of transverse force
A simple description of the relationship between the transverse force and the lifetime is not possible since the permissible transverse force depends on the direction of action and the magnitude of the operating force.
C) Dimensioning of the protrusion
Large tool protrusions over the work surface have an influence on the working result, the system load and the lifetime
of the cam unit due to geometric and static effects:
- high weight load on cam unit system due to large tool fittings on the work surface
- Multiplication of the effect by transverse forces due to lever mechanisms
- noticeably faster influence on the work result by lever effect through possible changes in the clearance
- changed damping behaviour
In general, you should therefore endeavour to achiev the smallest possible protrusion in the working area. Standard
punching lengths (including retainer plate) + approx. 50 mm can be assumed as a guide.
Overhangs in front of the working surface, which go beyond this guideline, are also possible, but must be checked
and evaluated in the course of the die design. FIBRO is pleased to advise and support you.

d) Application of compensatory forces
In the case of eccentric operating forces, the total force distribution can be positively influenced by introducing compensating forces. Appropriately dimensioned springs are arranged on the work surface for this purpose, which act
against the lower die or against the mounted main pad. Through the use of compensating forces, the total force as
well as the total centre of the force change. Accordingly, compensating elements must be taken into account during
the course of the cam unit design.
Compensation elements behave analogously to slider strippers. Their force continues to be applied after the end of
the working process, for example, after cutting through the sheet metal. The centre of the force of the compensating
forces must therefore also be compared with the permissible cam forces in order to make a sound statement about
the applied cam force possible (solution path, see chapter "Cam stripper").
Example:
The following values are known for one application case:
Process parameters cam unit: 2016.24.150.015.1000.0
Working width: 150 mm
Angle: 15°

The forces and centres of the force are as follows:
FP1 = 41.0 kN / xC1 = 12.8 mm / yC1 = 62.2 mm
FP2 = 52.2 kN / xC2 = 19.2 mm / yC2 = 146.6 mm
FPtotal = 93.2 kN / xCtotal = 16.4 mm / yCtotal = 109.5 mm
The forces of the cam unit are absorbed by means of a solid cast shoulder on the back of the cam base. Accordingly,
the proof of lifetime results after comparison of the forces with the cam load diagram:
FP1 < Fzul
41 kN < 98 kN -> Loading by punch P1 permissible
FP2 > Fzul
52.2 kN > 46 kN -> Loading by punch P2 not permissible
FPtotal > Fzul
93.2 kN > 70 kN -> Loading by load sum not permissible
Corresponding to the calculation results, constructive countermeasures must be provided in order to avoid overloading and thus a reduced lifetime of the cam unit. The centre of the force of the punch P2 as well as the total centre of
the force must be moved further towards the middle of the cam unit. For this purpose, a compensating spring is to be
provided on the working surface of the cam which acts against the main pad of the die:
Selected spring: FIBRO 2487.12.02400.016 (POWERLINE)
Spring nominal force: 24 kN
Mounting position x/y: 105 mm / 62.2 mm
By means of this additional spring, the total centre of the force point of the punch P2 and of the spring is shifted to
the following coordinates:
FCompensation = 72,6 kN / xCcompensation = 46,2 mm / yCcompensation = 120 mm
