Step Description

Define the cam disk by means of the interpolation table or polynomials, depending on the type.

Modify the scaling, interpolation type of the cam disk.

Close CamEdit.

Result: The technology object is inserted.

Note

After it is interpolated, new polynomials or interpolation points can only be added

after resetting the cam disk.

During interpolation and in the continuity check, the properties of leading and

following axes are neglected.

4.7.2 Defining cam disks

In the Insert cam dialog box, you can choose to define the cam disk based on

interpolation points or polynomials.

• Definition based on interpolation points

In the interpolation point table, the interpolation point are described by the

formula P = P(x,y). The order in which the value pairs are entered is irrelevant.

They are automatically sorted in ascending order in the domain.

S7T Config interpolates the cam disks according to the configured interpolation

type.

• Definition based on polynomials / segments

The various polynomials are described in accordance with "VDI 2143, Motion

Laws for Cam Mechanisms." The maximum degree of the polynomial is 6 and

can also contain a trigonometry function.
