Machine Definition
The first step in developing a 4/5X post-processor is defining the machine.
GPP2 contains a powerful "solver" that can handle practically any combination of machine axes and calculate the proper rotation angles needed to reach any tool orientation.
GPP2 can also handle the machine geometry, correcting any tool point translation caused by the axes rotations. However, this requires knowledge of the machine geometry (For example, the distance between the table rotation axis and the table face).
Finally, GPP2 can optimize the resulting G-code, minimizing the number of breaks in the milling process (where the tool has to be lifted from the material, and the machine needs to be rotated before cutting can continue).
In order to achieve all this, GPP2 must have a complete machine definition.
