 Helical cuts; how to set up?

I'm trying to cut a female thread (3/4 inch BSP parallel) and cannot get the helical cut to work. There don't seem to be any appropriate help files. Can someone point me in the right direction?

Thanks in advance!

Hello Tim

For a female thread (= threaded hole) you should simply use a CNC Tap tool. Apply the thread attribute to the holes in the model (in CAD) and then define a hole operation (e.g. center, drill, tap).

Tim,

You need to add hole feature and choose cylinder, select your filter to surface cylinder. Then add an operation, helixal cut, add your hole feature and a tool and set you pitch then calc.

Let me know if you have any other questions.

Hi Tim,

One other method that may be used is to generate a sprial curve that represents the center line of the tool path (this gives you all the control you would ever need by generating 3D wireframe) add the curve to the camplan as you would any other curve. Use 3X engrave with only the curve added and a tool, calculate that, the tool follows the curve you created.

I hope this helps.

Best Regards,

Randy
