Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment | BASIC ROTATION over two studs

(Cycle 402, DIN/ISO: G402)

Please note while programming:

Before a cycle definition you must have programmed a

tool call to define the touch probe axis.

The TNC will reset an active basic rotation at the

beginning of the cycle.

If you want to compensate the misalignment by rotating

the rotary table, the TNC will automatically use the

following rotary axes:

C for tool axis Z

B for tool axis Y

A for tool axis X

Danger of collision!

Cycles for coordinate transformation must not be active during

execution of the touch probe cycles.

Do not activate the following cycles before using touch probe

cycles: Cycle 7 DATUM SHIFT,Cycle 8 MIRROR IMAGE, Cycle

10 ROTATION,Cycle 11 SCALING and 26 AXIS-SPECIFIC

Reset any coordinate transformations beforehand
