4.9 Circular interpolation with polar coordinates (G2/G3, AP=, RP=)
Programming a circle with polar coordinates
The circular movement
is defined by:
• The polar angle AP=
• and the polar radius RP=
The following rule applies:
The pole lies at the circle center point.
The polar radius corresponds to the circle radius.
Programming
G2/G3 AP= RP=
Parameters
G2 Circular interpolation clockwise
G3 Circular interpolation counterclockwise
