Compound angle problem

[jonathanw]

I am trying to drill a hole with 36 degrees of rotation and a 55 degree tilt. Far as I can tell I am drawing the compound angles correctly. However when I go to run the program on a test part the drill is entering approx .600 off to the left of the center of the hole. I have attached the file I am working with along with the toolpath. If someone would double check what I have I would appreciate it.

This is the position geometry from the post. G55 X10.2085 Y2.0342 B-35. A22.623

Hi, I'm new on 5 axis in Mastercam and I had the same problem. I fixed mine. I opened your file and you have the same problem, for what I understand, the point of rotation in your machine has to be the same as your WSC. you have to check the position of your part at the machine, then go to mastercam and check that is in the same location. The problem that I had it's the I had the part 2" diference in Z axis betwen machine and Mastercam, simulation looked good but at the machine it was Like 3 inches off. This is my first 5 axis real program in mastercam, I might be wrong but in your program you won't be able to use your G55 WCS, you have to use TOP WCS. with out now the control, and machine that you are using is hard to explain, can you provide that information.

Because I have a swivel-head for my 3 axis CNC mill these problems always interest me.
I don't have MC so unable to read your file.
Can you please post a wire frame drawing of a box showing the hole axis with angles shown.
If you can post in another format may help. IGS, Step etc.
