Calling tool data
A TOOL CALL block in the part program is defined with the
following data:
ú Select the tool call function with the TOOL CALL
key
ú Tool number: Enter the number of the tool. The
tool must already be defined in a TOOL DEF block
or in the tool table.
ú Working spindle axis X/Y/Z: Enter the tool axis.
ú Spindle speed S
ú Tool length oversize: Enter the delta value for the
tool length.
ú Tool radius oversize: Enter the delta value for the
tool radius.
Example:
Call tool number 5 in the tool axis Z with a spindle speed 2500 rpm.
The tool length is to be programmed with an oversize of 0.2 mm,
the tool radius with an undersize of 1 mm.
20 TOOL CALL 5 Z S2500 DL+0.2 DR-1
The character D preceding L and R designates delta values.
Tool change
The tool change function can vary depending on the
individual machine tool. Refer to your machine tool
manual.
Tool change position
A tool change position must be approachable without collision. With
the miscellaneous functions M91 and M92, you can enter machine-
referenced (rather than workpiece-referenced) coordinates for the
tool change position. If TOOL CALL 0 is programmed before the
first tool call, the TNC moves the tool spindle in the tool axis to a
position that is independent of the tool length.
Manual tool change
To change the tool manually, stop the spindle and move the tool to
the tool change position:
ú Move to the tool change position under program control.
ú Interrupt program run (see section 11.3 “Program Run”).
ú Change the tool.
ú Resume the program run (see section 11.3 “Program Run”).
