Need to contour a elbow

[randommachinist]

Hey guys, I have a little dilemma. Basically, I have a cylindrical part with an OD of around 7 inches. Then I have an offset hole that's around 4 inches that starts at the top of the part and then exits out the side of the cylinder, creating kind of an elbow. I have about .100 that I need to surface off in order to clean up my elbow.  I can bore In from the top and side of the hole. But, that still leaves a gray area where the elbow makes that 90 degree turn. However, I have a coromill that's basically like a inserted disk that I plan on using to reach those areas. Does anyone have any suggestions to what kind of tool paths I would use to accomplish this? I noticed that whenever I try to use a pocketing tool path on my elbow, I get a "Warning-the boundary does not lie in the construction plane" error. I don't know what this means. I'm new to Mastercam and know very little. Any input is appreciated. thank!

Moving this to the proper forum as it's not a machine question

I'm not sure what toolpath you need, but I see that message when I have the wrong tool/construction plane selected.

Take your contour and use xform-project to project to your plane

I ended up using Surface Finish Contour. Worked pretty good.
