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).
