Facing in X5

[veteranbicycle]

This is my first post in this forum.

I learned Mastercam X7 in school several years ago, and now at my job I'm using X5 after not using Mastercam for a while. It's taken a couple of days of refamiliarization, but I've got WCS down, and now I'm writing my first toolpaths. I have experience using other platforms, mostly from Autodesk but also Solidworks Cam.

In facing, I'm having trouble controlling how many passes it makes. No matter how much stock is above the part, it always takes one pass. I setup the stock with Z +5mm, and set the depth cuts to be 1mm max rough step (0 finish cuts, 0 finish step), expecting to get 5 roughing passes, however I still get only one pass.

Clearly I'm doing something wrong. What would prevent facing from having multiple roughing passes?

If I set the rough step to be 0mm, and 5x finish cuts at 1mm finish step, I get 5 passes. My expectation would be to have multiple roughing passes and a single finishing pass, like I said above I can't program that for some reason. Any ideas?

Sorry can't look at that version. Sounds like your doing it correct. Make 2 operations using the finish pass process for 5 cuts. Leave .05mm on the one you make as the roughing and then you have the finishing like you need and move on.

I've never been a fan of the facing toolpath. I create a boundary and use pocket instead. Using that method, you have top of stock (where to start cutting), depth (where to finish cutting) and depth cuts (your step down). It's pretty simple at that point.

Check to see if your absolute or incremental depths are correct
