Calling tool data

A TOOL CALL block T in the part program is defined with the following
data:

Select the tool call function with the TOOL CALL key.

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. The TNC automatically places the tool
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.

Working spindle axis X/Y/Z:

Enter the tool axis.

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. Instead, you can define the cutting speed Vc in
m/min. Press the VC soft 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.

Tool length oversize DL:

Enter the delta value for

the tool length.

Tool radius oversize DR:

Enter the delta value for

the tool radius.

Tool radius oversize DR2:

Enter the delta value for

the tool radius 2.

Example: Tool call

Call tool number 5 in the tool axis Z with a spindle speed of 2500 rpm
and a feed rate of 350 mm/min. The tool length is to be programmed
with an oversize of 0.2 mm, the tool radius 2 with an oversize of
0.05 mm, and 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
parameter, or type the tool name in quotation marks.
