Programming tool lift-off with a defined vector
Example
18 FUNCTION LIFTOFF TCS X+0 Y+0.5 Z+0.5
With LIFTOFF TCS X Y Z, you define the lift-off direction as a vector
in the tool coordinate system. The control calculates the lift-off
height in each axis based on the tool path defined by the machine
tool builder.
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the PROGRAM FUNCTIONS soft key
Press the FUNCTION LIFTOFF soft key
Press the LIFTOFF TCS soft key
Enter X, Y, and Z vector components
Programming tool lift-off with a defined angle
Example
18 FUNCTION LIFTOFF ANGLE TCS SPB+20
With LIFTOFF ANGLE TCS SPB, you define the lift-off direction
as a spatial angle in the tool coordinate system. This function is
particularly helpful for turning operations.
The SPB angle you enter describes the angle between Z and X. If
you enter 0°, the tool lifts off in the tool Z axis direction.
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the PROGRAM FUNCTIONS soft key
Press the FUNCTION LIFTOFF soft key
Press the LIFTOFF ANGLE TCS soft key
Enter the SPB angle
