Overview form
The overview form summarizes the most important settings of the
unit. These parameters are repeated in the other forms.
Tool form
You program the technological information in this form.
Tool:
T: Tool number – turret pocket number
TID: ID no. – the tool name is entered automatically
F: Feed – feed per revolution (mm/rev) for machining
The tool is moved by the programmed value at each spindle
revolution.
S: Cutting speed (m/min) or Constant speed (rev/min)
Switchable with Type of turning GS.
Spindle:
GS: Type of turning
G96: Constant Cutting speed
The rotational speed changes with the turning diameter.
G97: Constant speed
Rotational speed is independent of the turning diameter.
MD: Turn. direct.
M03: Clockwise (CW)
M04: Counterclockwise (CCW)
SPI: Workpc spindle no. 0..3 – spindle that is holding the
workpiece (only on machines with more than one spindle)
SPT: Workpc spindle no. 0..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.
