I'm trying to figure out how to create geometry and/or toolpaths to helical mill a series of slots. I use helical milling frequently, but just circular features. I would even be happy with ramping help, however, the slots are 24mm x 20.5mm and 18.5mm x 16.5mm wide. This doesn't allow much of a straight movement to allow for a ramp move. I am using a Dapra Felix2010 0.55" dia. 2FL E/M and machining a gray cast iron. The CAD/CAM software I'm using is Surfcam Velocity II. Any help with this matter will be greatly appreciated. With this capability, I can eliminate two timely drilling cycles and tool changes. Thank you.
