Programming a helix
 Polar coordinates angle:
Enter the total angle of
tool traverse along the helix in incremental
dimensions. After entering the angle, specify the
tool axis with an axis selection key.
 Coordinate
: Enter the coordinate for the height of the
helix in incremental dimensions
 Direction of rotation DR
Clockwise helix: DR–
Counterclockwise helix: DR+
 Enter the radius compensation according to the
table

Always enter the same algebraic sign for the direction of
rotation and the incremental total angle IPA. The tool may
otherwise move in a wrong path and damage the contour.
For the total angle IPA you can enter a value of
-99 999.9999° to +99 999.9999°.
