Arrow of Light – Pockets

This is the most time consuming operation in the project.  Each of the pockets must be cleared to a depth of 3mm.  The geometry defining the pockets is all in a single sketch and a single pocket operation has been added.

Ideally, the cutter would move forward as it descends into the material, either in a ramp or a helical motion.  Unfortunately, HeeksCNC doesn’t have the ability to calculate those entry moves so I have to use a cutter that can ‘plunge’.  In this case I’m using a fairly small (1/4″) router bit.  That means the paths have to be close together and the overall cutting time is going to be large.  If I was going to do this commercially, I’d have to find a way to use a larger cutter.
