Radius Turning ( G02 & G03)
G02:- Circular interpolation clockwise (CW) G03:- Circular interpolation counterclockwise (CCW) The code G02 or G03 is used to move the tool in curve line. This codes are used for turning radius on CNC lathe machine and for making curve or circular cutting on CNC milling machine. When making a curve cutting, G02 code is used if the tool is moving clockwise FORMAT:- G02 X_ Z_ R_ F_ ;(Lathe machine) Clockwise circular movement Example:- G0 Z0; G0 X1; G2 X4 Z-1. 5R1.5F0.01; G1X15 F0. 05; and the anti-clockwise code is using G03. FORMAT:- G03 X_ Z_ R_ F_ ;(Lathe machine) Counter-Clockwise circular movement Example:- G0 Z0; G0 X1; G3 X4 Z-1. 5R1.5F0.01; G1X15 F0. 05; These codes are used in the block where the rounded part ends.
