cnc turning G codes


G00 Rapid traverse motion; Used for non-cutting moves of the machine in positioning quick
to a location to be machined, or rapid away after program cuts have been performed.
Maximum rapid motion (I.P.M.) of a Haas machine will vary on machine model.
G01 Linear interpolation motion; Used for actual machining and metal removal.
Governed by a programmed feed rate in inches (or mm) per revolution (G99).
Maximum feed rate (I.P.M.) of a Haas machine will vary on machine model.
(Inch Per Minute = R.P.M. x Inch Per Revolution).
G02 Circular Interpolation - Clockwise.
G03 Circular Interpolation - Counterclockwise.
