Call tool data
A 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. With the TOOL NAME
soft key you can enter a name. With the QS
soft key you enter a string parameter. The TNC
automatically places the tool name in quotation
marks. You have to assign a tool name to a string
parameter first. Names always refer to an 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. There is a SELECT soft key for
calling a window from which you can select a tool
defined in the tool table TOOL.T directly without
having to enter the number or name
Working spindle axis X/Y/Z: Enter the tool axis
Spindle speed S: Enter the spindle speed S in
revolutions per minute (rpm). Instead, you can
define the cutting speed Vc in meters per minute
(m/min). Press the VC soft key
Feed rate F: Enter feed rate F in millimeters per
minute (mm/min). The feed rate is effective until
you program a new feed rate in a positioning block
or in 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
