Recommended cutting data

Starting values for stable conditions with good coolant supply. Adjust for your machine, set-up and workholding. For diameters between the listed values, interpolate between the neighbouring rows.
Spindle speed n = Vc × 1000 / (π × D)  ·  Feed rate vf = n × fz × z (drills: vf = n × fn).

Ap and Ae refer to the corner radius R and cutter diameter D. For corners, reduce the speed by about half and the feed by 50–60%. For ramping (about 1°), reduce the feed to 60–70%.
