Just an update. The multi pass approach is working well. I read somewhere that the depth of each pass should not be more than the width of the bit as a rule of thumb. I've been sticking to that and all is well.

I did some climbout tests, and for my application, climbout left shreds hanging on the part I was cutting rather than on the surrounding Lexan so I am sticking with regular milling.

Using a speed of 15 ipm did not leave the part quite as smooth as 10 so I am using 15 ipm for the initial depth passes then I do a final pass at 10 ipm and cut the entire thickness but just the last .01 inch. That removes any artifacts from the multi pass and leaves a nice finish.
