CNC parameters: Channel and tool

The transformation parameters for the CNC channel and the tools are supplied to the transformation by means of transfer parameters (pointer p to structure TcNcTrafoParameter).

If a tool is selected (D word, see [PROG//Tool geometry compensation], the sum of the kinematic parameters is transferred from the channel parameter list and the tool.

Example:

  Channel parameter list:  kinematic[65].param[2]         300000

  Selected tool: wz[5].kinematic.param[2]       500000

Transferred transformation parameter: p->para[2] = 800000

Attention

attention

The transformation parameter with index 0 (kinematic[..].param[0]) always acts in the direction of the 3rd main axis (normally the Z axis) and is also included in the calculation of the tool length. Therefore, if the unchanged length of the tool is required for the transformation, this parameter should not be used.
