thread milling

[turbothis]

can i use a 60 degree double angle cutter to mill threads on mach 3 using the partmaster pro?
if so how do i go about doing this?

thanks

Should be no problem. I don't know about your cam system, but you can just use normal G code as well. Your radius will be your major diameter minus the cutter diameter divided by 2. G3 is a helical interpolation if you give a Z coordinate and a lead value as well.

PartMaster Pro (Level 3 in the UK) has a threadmilling function.

Define a Pattern in Cad as though you were going to drill it, then in Cam use the Threadmill item from the main operations toolbar.

Using the standard mach3 post "m_mach3" will output consectutive G02/3 moves with a corresponding move in Z.

I will upload an example program and drawing.

Hope this helps

Thats what I was going to say. Use the threadmilling option in the cam.
