Tool number:
Enter the number or name of the tool.
The tool must already be defined in a G99 block or in
the tool table. To call a tool by the tool name, enter
the name in quotation marks. The tool name always
refers to the entry in the active tool table TOOL.T. If
you wish to call a tool with other compensation
values, also enter the index you defined in the tool
table after the decimal point.

Spindle axis Z — XY plane
: Enter the tool axis. To
transfer the default setting G17, press the ENT key. If
you wish to select a different tool axis, use the soft
keys.

Spindle speed S:
Enter the spindle speed directly or
allow the TNC to calculate the spindle speed if you are
working with cutting data tables. Press the
S CALCULATE AUTOMAT. soft key. The TNC limits
the spindle speed to the maximum value set in MP
3515. Confirm the speed you have entered by
pressing the ENT key.

Feed rate F:
Enter the feed rate directly or allow the
TNC to calculate the feed rate if you are working with
cutting data tables. Press the F CALCULATE
AUTOMAT. soft key. The TNC limits the feed rate to
the maximum feed rate of the slowest axis (set in
MP1010). F is effective until you program a new feed
rate in a positioning block or a T block. Confirm the
feed rate you have entered by pressing the ENT key.

Tool radius oversize 2
: Enter the delta value for the
tool radius 2 and confirm with the ENT key.
Example: Tool call
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.
The character D preceding L and R designates delta values.
Tool preselection with tool tables
When you use tool tables, enter a G51 block to preselect the next tool
to be selected. Simply enter the tool number or a corresponding Q
