Ramp Angle

For Rough Parallel, Rough Spiral and Cleanup.
Angle of cutter entry into the material. An angle of 90 degrees means that there is no ramping.

Ramping is a tool entry method whereby the tool enters the part by gradually increasing in depth, preventing any shock loading on the tool to avoid poor tool life or premature tool failure. The angle of entry is determined by a defined ramp angle.

If the angle is less than 90 degrees , the cutter approach will be by helical motions. In this case, a Plunge Diameter must be specified. (This parameter is the diameter of the helical approach).
