Call tool data

A TOOL CALL block 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
TOOL DEF 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 in rpm.
Alternatively, you can define the cutting speed Vc
in m/min. Press the VC soft key
Feed rate F: F [mm/min or 0.1 inch/min] stays
effective until you program a new feed rate in a
positioning or T block
Tool length oversize DL: Delta value for the tool
length
Tool radius oversize DR: Delta value for tool
radius
Tool radius oversize DR2: Delta value for tool
radius 2
If you open a pop-up window for tool selection, the
TNC marks all tools available in the tool magazine
green.
You can also search for a tool in the pop-up window.
To do so, press the SEARCH soft key and enter the
tool number or tool name. With the OK soft key you
can load the tool into the dialog box.
