A very useful addition to this program would be the ability to make gear cutters, just the reverse of what it generates so well now.

I could see at least two really good uses for cutter generatio n:

1. Those cases where the gear teeth are so small that no milling cutter is small enough. A cutter could be made for exactly that gear and avoid the commercia l approxima tion cutters.
2. Those cases where it would be easier to shape the gear teeth.

I suppose that code to generate Hobbs wouldn't be bad either.

Hi:

   Gear cutter code will be put out very soon. I will be off on vacation shortly until about the 20th of March, when I return
we'll have a conversat ion here about just how folks would like that to work. As I developed GT, I made sure hooks were there to allow for
cutter generatio n so I already have most f the code done, its really just a matter of how best to do it. Ill rely on those that have experienc e
in such things to advise on best practice. It shouldnt take long once I begin.. ( Doesnt usually anyway.. Smiley )

Keep single point flycutter bits in mind.

Maybe have an option for thin versions so they can gash, finish left, finish right? Bigger teeth might need this.

Allow stretchin g to compensat e for rake and clearance angles?

Thanks.

The code is nearly there.

On the DXF of a gear  is the shape of the cutter, just delete the gear and put the shape thru a CAM program to get your cutter.
