This isn't a Tormach specific question, but since the community here is nice and it's the machine we've got I decided to post here. We have a part that we need to machine with a chamfered shoulder (see attached picture, the chamfer is some 5mm tall). When we had the part done outside, the contractor would run a regular endmill in various steps as to simulate the chamfer, giving us a staircase-like jagged effect. Since this chamfer is there mainly for cosmetic purposes and we now have a Tormach at our disposal, we want to do it right. I've never used a zero-point chamfering tool before, but I'm assuming the zero-point actually has some actual physical dimension that would prevent the bottom surface from being perfect after the chamfering operation.
Any suggestions on how to proceed?

If it's a 45-degree angle, you could do it with a 90-degree spotting drill, making two or more passes to cover the entire chamfer area.

If its just cosmetic, you could use a radiused corner endmill, I dont know what the correct terminology is for it.
Depending on the part the whole pocket could be machined with it.

Ball nose end mill. Much easier.

Can you give a better discription of the part? Is it a straight wall? Is it in the bottom of a pocket? Is it on an island where you cut all around the part?

There are lots of people who can help you here, but the discription you have given is rather vague.

If I understand correctly you want a chamfer on the inside corner between a vertical and horizontal edge. I believe that the cutter you need is called a bull nose end mill. These are available as normal mills and with inserts. Google for lots of photos and manufacturers. See HSMWorks for a picture. As one example of one using inserts see Bull Nose End Mills ? KDMT
