Using kinematics in die sinking

It is only possible to use kinematics in the die sinking configuration under the following two conditions:

1. The forward and backward transformation of the kinematic used must be unique. If a TcCOM transformation is used, the Boolean value f_UniqueTrafo must be set since a TcCOM transformation is normally not interpreted as unique.
2. Motions where kinematics have an influence on axis motions may only be programmed for erosion on the path (in the following example, motion of the C axis). The influence In the down channel geometry cannot be considered due to the 2D superposition of the down/escape channels.

In order to use kinematics, the kinematics in the down channel must be selected before activation of the escape channel. The identical kinematics must be activated in the escape channel before the geometry. It may not be deselected in the escape channel before program end.

Example

Offset of the electrode centre point in relation to the C axis

In subsequent NC programs for the down and escape channels, the kinematics in the figure are defined as TcCOM transformation ID 503 with the radial offset in parameter 4. With this kinematic, a compensation motion must be executed when the C axis is moved so that the electrode centre point remains at the same position.
