Fill in my knowledge gap :)

A little more gap to fill...

How do you program an edge chamfer or break an edge in CNC??

I have Aspire but no idea on this one?

I would guess at using a 45deg tool but is there a method to offset the correct amount and set the depth?

I am no expert by any stretch of the imagination, and I also struggled with this one ! What I ended up doing was just a case of simple maths, taking your 45deg cutter, You could assume that 0, 0, 0, puts the tip of the cutter right on the edge of your part, I then just told mach3 that I was using a 4mm cutter (doesn`t matter what size you insert here as long as it corresponds with your depth of cut) and used a cutting depth of 2.5mm. This in turn would put a .5 chamfer (in my case just a regular countersink) right round the edge of your part. If you required a larger chamfer, then simply lower the cutter to a depth of 3mm. Hope you can understand what I`m trying to say here
