Introduction to 5 Axes Post-Processing

Post-processing for 4 and 5 axes machines is a fairly complex task. It requires good understanding of the machine structure and kinematics, as well as the machine controller. It involves complex mathematics, which is handled by GPP2.

From the post-processor developer viewpoint, the following aspects must be mastered:

• Definition of the machine (axes, geometry, angle limits, etc.)

• 5X connections, where milling must be paused and the machine rotated between toolpath segments (or drill cycles).

• Work planes, both in GPP2 and on the machine itself.

• RTCP Settings and their effect

This Help provides the complete information necessary for developing 4/5X post-processors with GPP2. It assumes the reader is familiar with 5X machines and with 4/5 NC programming using Cimatron.
