Travel commands with polar coordinates (G0, G1, G2, G3, AP, RP)

Travel commands with polar coordinates are useful when the dimensions of a workpiece or
part of the workpiece are measured from a central point and the dimensions are specified in
angles and radii (e.g. for drilling patterns).
Syntax

Command for the activation of rapid traverse motion
Command for the activation of linear interpolation
Command for the activation of clockwise circular interpolation
Command for the activation of counter-clockwise circular interpolation
Polar angle
Angle between the polar radius and the horizontal axis of the working plane (e.g. X axis for
G17). The positive direction of rotation runs counter-clockwise.
Range of values: ± 0...360°
The angle can be specified either incremental or absolute:
Absolute dimension input
AP=AC(...):
Incremental dimension input
AP=IC(...):
With incremental dimension input, the last programmed angle applies
as reference.
The polar angle remains stored until a new pole is defined or the working plane is changed.
Polar radius
The specification is always in absolute positive values in [mm] or [inch].
The polar radius remains stored until a new value is entered.
