A axis milling

[David Czerw Triumph Gear Systems]

Guys,

I have uploaded a file on the ftp in mc9 folder called helix1.mc9. What I am trying to do is cut the groove in the part. It is a surface. I want to cut this using the "A" axis on a vertical machine center. I cant seem to get the axis to move right. I would like the "Y" axis to stay at zero and have only the "X,A. and Z" to move. Please help I'm having a terrible twith this

Try curv 5 axis toolpath. I've used it to do helical grooves on a Haas VF4 VMC with "A" axis in the past. Worked fine. HTH !

I tried that. Must be something I'm doin wrong. The tool goes right thru the surfaces

Are yo driving a curv ? How is your z depth set ?

Are you using a form tool cutting on center to get the shape?

[robertf]

The shape is a gear tooth,, so must be a form cutter,,

nope just a ballnose endmill. Parts will be ground afterwords

Hello

 

I seem to be having a hard time getting it to wark as well. Have you tried creating a helix down the center of the groove then unrolling it and using an axis substitution toolpath? Unfortunately in the past I have wussed out and went that route when time ran out.
