5.3 Path Functions
Function Input in Cartesian Input in polar
coordinates coordinates
Straight line at rapid traverse G00 G10
Straight line at programmed feed rate G01 G11
Chamfer with length R. G24
A chamfer is inserted between two straight lines.
Circle center – also the pole for polar coordinates. I, J, K
I,J,K generates no movement.
Circular arc, clockwise (CW) G02 G12
Circular arc, counterclockwise (CCW) G03 G13
Programming of the circular path:
• Circle center I, J, K and end point, or
• Circle radius and end point.
Circular movement without direction of rotation. G05 G15
The circular path is programmed with the radius
and end point. The direction of rotation results
from the last programmed circular movement
G02/G12 or G03/G13.
Circular movement with tangential connection. G06 G16
An arc with tangential transition is inserted into
the preceding contour element. Only the end
point of the arc has to be programmed.
Corner rounding with radius R. G25
An arc with tangential transitions is inserted
between two contour elements.
