G01 X1.0 Y1.0 F3.0 Moves the tool directly to the Program
Coordinates X=1.0, Y=1.0 at a feedrate of
3.0 in/min.
G02 X3.0 Y3.0 I1.0 J1.0 Moves the tool using clockwise circular
interpolation to the Program Coordinates
X=3.0, Y=3.0 with a center point of X=2.0,
Y=2.0 at a feedrate of 3.0 in/min.

When using G02, there are several things to keep in mind:
• The command is modal, i.e. G02 is in effect until another move
command occurs (G00, G01, or G03).
• The interpretation of the X, Y and Z coordinates depends on the
G90/G91 command in effect. The I, J and K values are unaffected by
G90/G91.
• The tool will move at the current feedrate set by the last F command.
• Only XY arcs can be cut when G17 is active, only XZ arcs can be cut
when G18 is active and only YZ arcs can be cut when G19 is active.
• The clockwise direction of rotation is as viewed from the positive end
of the unused axis (the axis not in the plane of motion). For example,
a G02 arc move in the XY plane is clockwise as viewed from the
positive end of the Z axis (i.e. from above). The following diagram
illustrates this behavior:
