Using zig-zag ramping to mill a helical path for a simple groove

Zig-zag ramping can be used with a simple groove feature to create a generalized helical toolpath.

To produce this toolpath:

1. Set Max ramp angle to 90.

2. Set Max ramp distance to a very large number like 1000,.

3. Set Rough pass Z increment to a value less than the depth of the feature. In one pass around the groove, the tool will spiral down in Z an amount equal to Rough pass Z increment.

An alternative way to create the generalized helical toolpath is to:

1. Set Max ramp distance to 1000.

2. Set Rough pass Z increment to the depth of the feature.

3. Use the Max ramp angle to control the slope of the toolpath.
