Table RTCP

Table RTCP applies to machines with a rotating table (one or two axes). Rotation of the table actually has a double effect on tool tip positions:

• The part is rotated; hence the whole procedure UCS is rotated with it. This rotates and modifies every tool tip point.

• If the REF coordinate system is not located at the center of axis rotation, the REF UCS zero point is also shifted because of the axis rotation. That translation needs to be corrected on every tool tip point.

The following diagram illustrates table RTCP.

Table RTCP corrects the REF zero point translation (displacement). The controller adjusts the tool position in order to compensate for the rotation. It does not correct the procedure UCS rotation - that is handled by GPP2. In machines without table RTCP, GPP2 handles the full correction.

For machines with table RTCP, the M5_RTCP_TAB variable has to be set to TRUE_. For machines without table RTCP, it has to be to FALSE_.
