4. FUNCTIONS TO SIMPLIFY PROGRAMMING
The multi–piece machining function enables several sheets of product
with the same punching shape to be produced from a single sheet of
material at a time by simple commands.
This function allows so called “trial machining” that performs punching
only on a sheet of product from the machining command tape for
“multi–piece machining” by a simple setup method, therefore the
machining command tape can be easily checked before full machining.

Parts (2) to (9) as shown above have the same punching shape as part (1).
Machining commands to punch on a sheet of material must be specified
on the product part at the lower left ((1)).
The point at the lower left of the set of multi–products (point B shown in
Fig. 4.2.1; called as “Base point of multi–piece machining” hereafter)
must be specified prior to the machining commands to punch on a product
part by G98 as absolute co–ordinates under the system of co–ordinates
specified using G92 command. In the G98 command, the X–axial and
Y–axial lengths of one product and the numbers of products in the
directions of X–axis and Y–axis must be specified.
Y yb I ȏx J ȏy P nx K ny ;
xb: X–axis coordinate value of the base point of multi–piece machining
yb: Y–axis coordinate value of the base point of multi–piece machining
ȏx: X axial length of one product part (a positive number)
ȏy: Y axial length of one product part (a positive number)
nx: The number of products in the X axial direction (Note)
ny: The number of products in the Y axial direction (Note)
