6.2 Normalised laws of motion

Each cam segment i describes a cam profile part defined by the value range s

=f(ϕ

)ands

=f(ϕ

• Internally, the functions are calculated using the normalised

value range 0...1.

• The coefficients of the cam profiles indicated in the

properties dialogs also ref er to t he normalised value range.

• The velocity and acceleration values in the properties

dialogs show the boundary values based on the actual

geometrical dimensions. Accordingly, the calculation is

based on the formula

v=ds/d

ϕ and a = d

s/dϕ

The geometrical v alues for velocity and acceleration are

also used in the graphical representation.

7 Steps required for a new cam

The f ollowing steps are required to create a new cam profile:

• Selection of the worksheet settings

• Entry of technological requirements

• Join segments

• Adaptation of the acceleration (points)

• Generation of table interpolation

• Export of cam profile data

7.1 Selection of the worksheet settings

See chapter 5.1, “Worksheet settings”. (¶62)

1. Select File➞

➞New to create a new project.

2. Select Edit

➞➞

➞Project Settings to open the Settings dialog box.

3. Go to the Settings dialog box, select the Range tab and define the value ranges for the master

and slave axis as well as the units for the axes.

The limit values should be set slightly higher to ensure that the objects are not directly set at

the edge of the working area.

4. Go to the Settings dialog box, select the Machine tab and define the type of master axis and its

speed in the operating point. Both settings are needed to calculate speed and acceleration for

the slave axis.

5. If the target system requires special connections, go to the Settings dialog box, click the

Connections tab and select the connection type required. In all other cases, the automatic

selection of connection type should not be changed.

6. Close the Settings dialog box with OK.
