2003-2-5  For many machines, feed rate can also be specified in per-revolution fashion (either inches or millimeters per revolution). This makes feed rate specification easy. But one constant headache for programmers is that feed rate for most rotary axes must be specified in degrees per minute. Determining degrees per minute feed rate is cumbersome.

### What is Feed Rate in Machining? Its Unit, Value,

Feed rate in drilling—Must be very low otherwise tool may break due to chip clogging. Typical value is 0.01 – 0.05mm/rev. Feed rate in milling—Usually 0.05 – 0.10mm/rev. Feed rate in knurling—0.5 – 1.0mm/rev (Cutting speed is usually very small in knurling but feed rate is very high). Pros and cons of improper feed rate

### Turning Speed and Feed Calculator

Feed rate is the velocity at which the cutter is fed, or the rate advanced against the workpiece, often expressed in units of distance per revolution for turning, that typically is inches per revolution (IPR) or millimeters per revolution (MPR). Turning feed rate is determined by the type of cutting tools, surface finish desired for milling ...
