Which G-code is specifically used for circular interpolation in the XY plane?

Circular interpolation in the XY plane is accomplished using specific G-codes that indicate the direction of the circular movement. The correct answer indicates that G-code is crucial for controlling the movement of the milling machine in a circular path.

G02 is the G-code used for clockwise circular interpolation, while G03 is used for counterclockwise interpolation. Both of these commands dictate how the machine should follow a circular path in the XY plane. Options like G00 are for rapid positioning and do not pertain to circular interpolation, and G19 is actually used for defining a plane of operation in a different context (the YZ plane).

Thus, the G-codes specifically implemented for circular motion in the XY plane are G02 and G03, directly addressing the machining movements required to create arcs and circles.
