In this case, the command of “G73 W90 Q1” becomes identical with the
following series of commands.
G73 W01 Q1 ;
G73 W02 Q1 ;
G73 W04 Q1 ;
Though multi-piece machining commands (G73/G74) are generally used
to punch products of the same shape arranged at intervals of grid, they can
be also performed to punch exclusively in the X or Y axial direction.
In such a case, specify the number of products in the X or Y axial direction
(to be specified by address word P or K) in G98 to “0”.
When products are machined using a NC tape for multi-piece machining,
any desired machining method can be selected according to a set-up from
MDI.
Input a setting value into the setting data number 16206 in MDI mode
according to the desired machining method.
Setting value for No. 16206
0: The NC tape for multi-piece machining is not used
1: Trial punching for multi-piece machining
2: Machining on the reset of material punched for trial
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.
