Tplane needs to be defined for an indexing machine in a specific way. You need to pay attention that the coordinate axis' are correctly chosen. 1-rule is that Z needs to point out from the surface. 2nd rule is that either X or Y depending on the machine needs to be alongside the rotary axis. After that you can program the toolpath. Now that the coordinate system is correctly chosen the NCI-code for the program has specific vectors defined and it can calculate the indexing angle correctly if post is programmed for indexing axis calculations. Calculations are machine related so a generic post does not necessarily do the job for you. Worth trying tho. Depending on the machine design there could be plenty of other vital tricks to have the post working for you. Rotary table is typically easy, but rotary spindle may need some customisation. JH

Sorry, I couldn't help myself but this Forum has a celebration.

I'm offering consulting for Mastercam-users in Finland and there's one idea which has been requested by several companies: 4-axis pocket machining so that all material within the pocket will be burnt rather than cut. The problem are the small islands falling down and potentially braking the machine. Lack of this feature greatly affects unmanned machining This is how I'm currently advicing to program this: Program a pocket to lower section and backplot generating geometry and then same to above section. After that one can program wirepath using lower and higher profile for pragramming the cutting. - Jussi
