5.5 Path Contours – Polar Coordinates
Circular path CP around pole CC
The polar coordinate radius is also the radius of the arc. It is already
defined by the distance from the pole CC to the starting point
S .
Input
• Polar coordinate angle PA for arc end point
• Direction of rotation DR
• For incremental values, enter the same sign for DR and PA.
• You can enter values from –5400° to +5400° for PA.
COORDINATES?
Select polar coordinates.
POLAR COORDINATES ANGLE PA?
Enter the angle PA of the arc end point PA = 10°.
ROTATION CLOCKWISE: DR–?
Set the direction of rotation for the tool path, for example negative for
clockwise rotation.
If necessary, enter also:
Radius compensation
Feed rate
