6.13 Preparing a Machining Process
Preparing a machining process – Fundamentals
The “Prepare” function defines the chucking equipment, the position
of the chucking equipment, and TURN PLUS specific turret
assignments.
For chucking a workpiece, TURN PLUS determines the following data:
Inside and outside cutting limit.
Zero point shift. The value is transferred to the NC program as a G59
command.
TURN PLUS transfers the following set-up information to the program
head:
Clamping diameter
Free length
Clamping pressure
You can set/change the cutting limits.
If you do not use “clamp” TURN PLUS assumes
standard values.
You define the chucking equipment for the second
setup after machining the first setup.
If you clamp the workpiece at the spindle and the
tailstock, TURN PLUS assumes that a shaft is
machined (see “Shaft machining” on page 557).
