Direction of rotation for circular movements
If a circular path has no tangential transition to another
contour element, enter the direction of rotation with the following
functions:
„ Clockwise direction of rotation: G02/G12
„
Counterclockwise direction of rotation: G03/G13
Radius compensation
The radius compensation must be in the block in which you move to
the first contour element. You cannot begin radius compensation in a
circle block. It must be activated beforehand in a straight-line block
(see “Path Contours—Cartesian Coordinates,” page 218).
Pre-positioning
Before running a part program, always pre-position the tool to prevent
the possibility of damaging it or the workpiece.
