SINUMERIK 840D sl Operation/Programming ShopTurn (BAT) – 08/2005 Edition
All parameters specified in the program header with the exception of
the blank shape and the unit of measurement can be changed at any
point in the program. It is also possible to change the basic setting for
the direction of rotation of machining in the case of milling.
The settings in the program header are modal, i.e. they remain active
until they are changed.
Any changed return plane takes effect starting with the safety
clearance of the last cycle, because the additional retraction from the
next cycle is completed.
The machining direction of rotation (down-cut or up-cut) is defined as
the direction of movement of the milling tooth with respect to the
workpiece, i.e. ShopTurn evaluates this parameter in conjunction with
the direction of rotation of the spindle for milling, with the exception of
path milling.
The basic setting for the direction of rotation of machining is
programmed with a machine data code.
Please also refer to the machine manufacturer's instructions.
