2d Dynamic milling over engage

[jas6142]

It seems like in 2d dynamic mill that the cutter over engages on the corners of stock, and doesn't use the max step over?  Is there a way to remedy that?

Always done that best thing to do is trim the cornered with a contour toolpath then run the dynamic toolpaths. I have some X7 files where I was breaking endmills 250% DOC with 10% ROC on 3/4 3 Flute endmills. Those corners were just enough to stress the endmills and break them. I did the process I just told you and problem was solved.

Because the raw stock can be heavy on one side and light on the other, and saw cut.  The dynamic toolpath needs to go around the stock once to understand where the material is.  Try giving it a first pass offset with feed reduction and you will achieve what you are looking for.

+1 For 1st pass offset, I always set mine to .100" because our sawed stk varies
