open pocket

[notso]

Hoping that one of you might have the solution to my open pocket problem. I'm using open pocket to rough all three sides of a triangular part (using transformed tool path. All was going well until I decided to change my geometry a little bit. After the geometry change (and rechaining the pocket) Mcam has decided to cut on the inside of the line instead of the outside. I've tried reversing the chain, tried both climb and convensional milling, but no matter what I do it still wants to cut on the wrong side of the line. As soon as I changed the Geometry back it worked fine again. Any suggestions? I'm really struggling here.

When you reverse the chain make sure that you're climb milling at the same time... When you reverse the chain sometimes mastercam reverses the comp @ the same time. So make sure you do bothh @ the same time...

Also check the path in iso. view. Is the tool entering from the bottom of the part? Only guessing.
