  1. I tried it once using ceramic buttons in Inconel and it worked OK.  I only had a few parts to machine (diameter 380 lg50) so I can't say about tool life but there were no notch wear as it could happen with standard toolpaths. 

  2. It can be done but as already said, best is to split in 2 ops. (or ask CNC a switch to calc rough passes with computer comp only...)

    IMHO it can cause serious issues tweaking a post that way... you can count passes number set in Mastercam GUI but if CNC changes/improves routines in a future release (as it's been done in 2018 if I remember correctly) you probably will need to be careful (I ve already been bitten...) 

    Another stuff to be aware: what if a user, one day, has great idea to post a toolpath with 'control' comp setting? It will make a crap part and a cutter broken...So don't forget to support that case in your post to output G41/G42.

  3. This is usually straightforward, you just need to chain top and bottom wire path. Just pay attention to synchronization as any ruled surface creation. I guess you already got it but you also need a power Mastercam tech file for your machine definition.
