What does a G02 code do?

G02 sets the CNC movement mode to clockwise circular movement, otherwise known as circular interpolation.

G02 is used to move the CNC around along a specified radius set with the R code in a clockwise direction and at a feed rate set with the F code.

G02 is a modal command which means it will stay on until switched to another code in the same movement group of codes such as G00 – Rapid travel, G01 – Linear interpolation or G03 – Counterclockwise circular interpolation.
