units
The Overview form
The overview form summarizes the most important settings of the
unit. These parameters are repeated in the other forms.
The Tool form
You program the technological information in this form.
Soft keys in the tool form
Selects the tool number
Loads the feed rate, cutting speed and
infeed from the technology database.
Tool form
Tool
T
Tool number (number of turret pocket).
TID The identification number (tool name) is entered
automatically.
F Feed rate: Feed rate in revolutions for machining (mm/rev).
The tool is moved at the programmed value for each spindle
revolution.
S (Constant) cutting speed (m/min) or constant shaft speed
(rev/min). Switchable with Type of turning GS.
Spindle
GS
Type of turning
 G96: Constant surface speed. The rotational speed
changes with the turning diameter.
 G97: Constant shaft speed. Rotational speed is
independent of the turning diameter.
MD Direction of rotation
 M03: Clockwise (CW)
 M04: Counterclockwise (CCW)
SPI Workpiece spindle number (0 to 3). Spindle that is holding
the workpiece (only on machines with more than one
spindle).
SPT Tool spindle number (0 to 3). Spindle of the driven tool.
M functions
MT
M after T: M function that is executed after the tool call T.
MFS M at beginning: M function that is executed at the beginning
of the machining step.
MFE M at end: M function that is executed at the end of the
machining step.
A machining operation is assigned to each unit for access
to the technology database. The following description
shows the assigned machining mode and the unit
parameters that were changed by the technology
proposal.
