Motion commands
4.2 Travel commands with polar coordinates, polar angle, polar radius
Fundamentals
122 Programming Manual, 11/2006, 6FC5398-1BP10-2BA0
Parameters
G0
Rapid traverse movement
G1
Linear interpolation
G2
Circular interpolation clockwise
G3
Circular interpolation counter-clockwise
AP=
Polar angle, value range ±0…360°, the polar angle can be defined
both absolutely and incrementally.
RP=
Polar radius in mm or inches always in absolute positive values.
=AC(...)
Absolute dimensioning
=IC(...)
Incremental dimensioning
Example of making a hole pattern
The positions of the holes are specified in polar coordinates.
Each hole is machined with the same production sequence: Predrilling, drilling to size,
reaming, etc. The machining sequence is filed in the subroutine.
