If I got it right trochoidal tool path is for milling slot with mill
diameter slightly smaller than slot and address the problem with large
tool engagement. Have not being thinking about a slot, it is a special
case with parallel walls close together not sure if the calculated tool
get constant tool engagement angle.
Expect force on tool to a large degree depend on tool engagement angle
though heat also ought to increase since tool machine for a longer
distance each turn. Expect force on tool also to some degree. Guess
these are good reasons to limit tool engagement angle.
Heat is a problem but above a certain surface speed heat get lower and
found someone claim HSM use constant tool engagement angle but there are
more problems to solve with HSM. They talk about advantages with HSM
machining that do not mention anything about the math to get constant
tool engagement angle in the corners. I want calculate constant tool
angle path to get rid of wobbling and other problems in corners.

Is this the same as the trochoidal tool paths used in HSM?
(I initially thought that you were talking about a lathe with a
rotating tool insert, but I am now thinking that you are talking about
milling)
