Cartesian pre-compensation

The sequence for measuring the axes plays an important role.

In the example, let us assume there is a 5-axis machine XYZBC with rotary and swivel axis in the workpiece.

If all 5 axes are measured simultaneously, one Volumetric Compensation CBYXZ is sufficient.

However, the following sequence is also possible:

• The axes YXZ are measured and compensated.
• Then the B and C axes are measured and compensated.

2 compensations are used:

• YXZ, Cartesian parameter file only
• CBYXZ, parameter files for the B and C axes only

This is how the measuring strategy of Cartesian pre-compensation used is mapped.
