The PROGRAM HEAD comprises:
■ Material – for determining the cutting values
■ Assignment of spindle to slide for 1st setup
■ Assignment of spindle to slide for 2nd setup
For full-surface machining, enter the spindle/slide for
machining the setup.
■ Spindle speed limit:
■ No input: SMAX is the spindle speed limit
■ Input < SMAX: Input is the spindle speed limit
■ Input > SMAX: SMAX is the spindle speed limit
SMAX: see machining parameter 2 (global
technology parameter – spindle speed limit).
■ ”M functions” button: You can define up to five M
functions which TURN PLUS will take into account
when generating the NC program.
■ At the beginning of the machining process
■ After a tool change (T command)
■ At the end of the machining process
The fields
■ Clamping diameter
■ Unclamping length
■ Clamping pressure
are calculated and automatically entered by TURN
PLUS in the ”setup” function (see ”
