For each new workpiece that you would like to finish, create an
individual program. The program contains the individual machining
steps that must be performed for finishing the workpiece.
If you create a new program, a program header and program end are
automatically defined. In the program header, you must set the
following parameters, which are active during the entire program.
The zero-point offset in which the zero-point of the workpiece is
saved.
You can also delete the pre-setting of the parameter if you do not
want to specify a zero-point offset.
The setting of the unit of measure (millimeters or inches) in the
program header is relative to the position specifications in the current
program. You enter all other specification such as feedrate or tool
offsets in the unit of measure that you have set for the entire machine.
For the blank of the workpiece, you must define the shape (cylinder,
tube, rectangle, or N-angle) and the dimensions.
W: Blank width – only for rectangle
L: Blank length – only for rectangle
N: Number of edges – only for N-angle
L: Edge length (alternative to SW) – only for N-angle
SW: Key width (alternative to L) – only for N-angle
XA: Outside diameter (abs) – only for cylinder and tube
XI: Inside diameter (abs or inc) – only for tube
ZA: Initial dimension (abs)
ZI: End dimension (abs or inc)
ZB: Machining dimension (abs or inc)
