4. FUNCTIONS TO SIMPLIFY PROGRAMMING
Specify any of the following commands, and then multi–piece machining
is performed by calling machining commands stored using the macro
ωn Q q ; or
ωn Q q ;
ωn: A macro number
q: Machining start area specification
q=1 Machining starts from the lower left area ((1) in Fig. 4.2.1)
q=2 Machining starts from the lower right area ((7) in Fig. 4.2.1)
q=3 Machining starts from the upper left area ((3) in Fig. 4.2.1)
q=4 Machining starts from the upper right area ((9) in Fig. 4.2.1)
G73 goes on punching in the X axial direction, whereas G74 goes on
punching in the Y axial direction in grid parts–line.
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
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
( (1) in Fig. 4.2.1). 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
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.
