Thanks a lot  for all, my friends.

Very good suggestions for this problem.

I always use 90 degree facemill for doing contour path before using endmill. This is saying endmill and saving time.

Just like using a 1'' cylinder to cut a rectangle, 0.38''*0.8'', it is fast way to cut by facemill, especially using for 303/304 stainless steel.

Anyway. Thanks again.

Hello, everyone.

I am using mastercam for a while. When I tried to use a 90degree facemill to do a contour toolpath, but mastercam tool library only offers 45degree facemill, I tried to modify to 90degree facemill, but it does not accept, always say wrong.

How can I create a 90degree facemill?

Please help me of this problem.

Thanks for your suggestions.

Thanks, my friend.

I already delete the lines related with that problem, it works.

Yes, the other way is to use '#" to make that line be a comment.

Anyway, thanks for your suggestion.

Colin G. My friend.

you are so smart. I checked my NC code. Before tool change there is the sequence number which is same with Tool number.

I do not know how to upload my post. Just paste some of post which are related with tool change. Please help me check and find where I am wrong. Thanks a lot.

Hell, everyone.

I am a starter on mastercam post file editing. I updated Mazak Post file from V9 to X5, and redefined control and machine file. Most of CNC code created by these new files look right, but the sequence number has problem. please see the red mark.
