Juggling Mismatches in Resolution and Least Input Increment
While CNC machining and turning systems of the past only had resolutions and least input increments equal to the displayed decimal places, new systems support more precise inputs.

Adjusting Feed Rate in Circular Motion Commands with G-Codes
While it is possible to calculate by hand adjustments to feed rate for circular milling operations, cutter radius compensation CNC programs streamline this process.

How to Modify Feed Rate for Circular Motion Commands
Maintaining a constant feed rate between linear and circular milling easily leads to chatter — for most applications, increase feed rate on external arcs and decrease it for internal.
