as
to hone the edge with a super fine diamond stone on some inserts to get a

Use the high positive rake inserts designed for aluminium, such as CCGT
or DCGT. They work well on most plastics. They also work quite well on wood.
As you are probably aware you will end up with long strings that get
tangled up in the work. It helps to program in pauses to break the
strings up.
I need to machine Delrin on my lathe. I have had good results with hand
sharpened HSS tools with moderate tip radius, and positive rake for my
manual lathe. For my HNC, I would like to use inserts with an accurate

What or how are you determining the corrections?
If you are using a glass scale, one could write a program to move the axis
slowly while recording 256 points of the motor encoder and glass scale encoder
then moving in the opposite direction doing the same thing. The glass scale
