Which command is used for circular interpolation in CNC programming?

The command used for circular interpolation in CNC programming is G02, which specifies a clockwise arc movement. This command allows the machine to move from one point to another in a circular path around a defined center point, making it essential for producing arcs and curves in a part being machined.

G02 requires parameters that typically include the radius of the arc or the endpoints of the arc relative to the center point. It's crucial for creating smooth transitions between straight segments of a path and is often used in applications such as machining gears, cam profiles, or any component requiring curved surfaces.

In conjunction with G02, G03 is also related to circular interpolation but is used for counterclockwise movement. While G01 is for linear interpolation and G00 is for rapid linear movement without regard to the path, G02 specifically highlights the clockwise arc function that is key to creating circular features in a workpiece.
