Programming a helix
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°.
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
Example: Thread M6 x 1 mm with 5 revolutions
