Note 4: All or some addresses of G76 P （ m ） （ r ） （ a ） Q （ △ dmin ） R （ d ） are omitted, and omitted addresses
runs according to the setting value;
Note 5: m, r, a uses the same address P to be input one time. When m, r, a are all omitted,the system runs
at the setting value of No.5142, No.5130 or No.5143; when P is with non regular value, the system
takes the last two digits of P value as a value, and the last threeth and fourth digits as r value, and
the left as m value;
Note 6: Signs of U, W determines direction of A → C → D → E, R (i) determines that of C → D. Four kind of
combincation of U, W correspond to 4 kind of machining path;
Note 7: When the set first thread cutting depth is more than the total cutting depth, one roughing is
executed, and its cutting depth is equal to the total cutting depth of roughing;
Note 8: When the least cutting amount or finishing allowance is more than thread tooth height in the
course of thread roughing, an alarm occurs;
Note 9: When the run-out length is more than the machining thread length of long axis, an alarm occurs;
Note 10: The system automatically checks the spindle speed before machining, an alarm occurs when the
spindle speed is not commanded. The spindle speed cannot be checked in the course of
machining;
Note 11
：
The run-out format is the same that of G32 when there is J, K.
