Calling the tool data

Before you can call the tool, you have to define it in a TOOL DEF
block or in the tool table.
A TOOL CALL in the NC program is programmed with the following
data:
Press the TOOL CALL key
Tool call: Enter the number or name of the tool.
With the TOOL NAME soft key, you can enter a
name. With the QS soft key, you enter a string
parameter. The control automatically puts the tool
name in quotation marks. You must first assign a
tool name to a string parameter. The names refer
to an entry in the active tool table TOOL.T.
Alternative: Press the SELECT soft key
The control opens a window where you can select
a tool directly from the TOOL.T tool table.
To call a tool with other compensation values,
enter a decimal point followed by the index you
defined in the tool table.
Working spindle axis X/Y/Z: Enter the tool axis
Spindle speed S: Enter the spindle speed S in
revolutions per minute (rpm). Alternatively, 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). Alternatively, you can define
the feed rate in millimeters per revolution (mm/1)
by pressing the FU soft key or in millimeters per
tooth (mm/tooth) by pressing FZ. The feed rate
is effective until you program a new feed rate in a
positioning block or in a TOOL CALL 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
In the following cases the control changes only the
speed:
TOOL CALL block without tool name, tool number, and
tool axis
TOOL CALL block without tool name, tool number,
with the same tool axis as in the previous TOOL CALL
block
In the following cases the control runs the tool-change
macro and inserts a replacement tool if necessary:
TOOL CALL block with tool number
TOOL CALL block with tool name
TOOL CALL block without tool name or tool number,
with a changed tool axis direction
