Using machining positions repeatedly
Whether or not you have created machining positions directly on the
form or as an HP file in the pattern generator, you can use these
machining positions for all programmed machining units that directly
follow. Just leave the input fields for the machining positions empty.
smarT.NC then automatically uses the machining positions previously
defined by you.
Machining positions stay effective until you define new
machining positions in any subsequent unit.
