4.7 Actual Position Capture
Sometimes you may want to enter the actual
position of the tool in a particular axis as a coordi-
nate in a part program. Instead of reading the actual
position values and entering them with the numeric
keypad, you can simply press the “actual position
capture” key (see illustration at right). You can use
this feature to enter, for example, the tool length.
To capture the actual position:
MANUAL OPERATION
Move the tool to the position that you wish to capture.
PROGRAMMING AND EDITING
Select or create the program block in which you wish to enter the actual
position of the tool.
Select the axis in which you wish to capture a coordinate,
for example X.
Transfer the actual position coordinate to the program.
Enter the radius compensation according to the position of the tool relative to the workpiece.
