Example 2: Correcting workpiece misalignment on machines
with rotary tables
Use the 3-D touch probe to rotate the coordinate system. See “Touch
Probe Cycles in the Manual and Electronic Handwheel Operating
Modes,” section “Compensating workpiece misalignment,” in the
Touch Probe Cycles User’s Manual.
Write down the rotation angle and cancel the Basic Rotation.
Select operating mode: Positioning with MDI.
Select the axis of the rotary table, enter the rotation
angle you wrote down previously and set the feed
rate. For example: L C+2.561 F50
Conclude entry.
Press the machine START button: The rotation of the
table corrects the misalignment.
