• Spindle speed S
To call the tool data:
TOOL NUMBER?
Enter the number of the tool as it was defined in the tool table or in a
"G99" block, for example 5.
Select the spindle axis Z.
Enter the desired spindle speed, for example S = 500 rpm.
Resulting NC block: T5 G17 S500
Tool pre-selection with tool tables
If you are using tool tables, you can indicate which tool you will next need
by entering a G51 block. Simply enter the tool number or a corresponding
Q parameter.
Tool change
Automatic tool change
If your machine is built for automatic tool changing, the TNC controls the
replacement of the inserted tool by another from the tool magazine. The
program run is not interrupted.
Manual tool change
To change the tool manually, stop the spindle and move the tool to the
tool change position. Sequence of action:
• Move to the tool change position (under program control, if desired)
• Interrupt program run (see page 3-4)
• Change the tool
• Continue the program run (see page 3-5)
