3: Full machining on a material for multi-piece machining
If trial punching is selected, only the lower-left product part of material
( in Fig. 14.5.1 (a) and (b)). As a result, macros except 60 to 89 are
executed while storing, and blocks specified in G73/G74 are all ignored.
Machining on the reset of material punched for trial signifies that after
punching on only the lower-left product part of material, the remaining
product parts of material are machined entirely. For this purpose, no
machining is performed during the storage of macros, and the machining
on the lower-left product part is skipped when commands of G73/G74 are
executed.
For full machining on a material, no machining is performed during the
storage of macros, but machining over the entire product parts is
performed by G73/G74.
Set to “0” if NC tape for the multi-piece machining is not used.
Specifying the position from which machining multiple products restarts
with address P in a block in which the G73 or G74 command for
machining multiple products is specified enables machining multiple
products to restart from the specified position.
Command format:
G73 (G74) W w
Q q P p ;
w : Macro number
q : Machining sequence
p : Position from which machining restarts
A P code specifies the position from which machining
multiple products restarts in a block where a G73 or G74
command is specified and a Q code is used to specify a
machining area.
Valid setting: 1xpxtotal number of products to be
machined
