) R(d) . The omitted address runs
according to setting value of parameters;
●
m, r, a used for one command address P are input one time. Program runs according to
setting value of
№ 57, 19, 58 when m, r, a are all omitted; Setting value is a when address
P is input with 1 or 2 digits; setting values are r, a when address P is input with 3 or 4
digits;
● The direction of A → C → D → E is defined by signs of U,W , and the direction of C → D is
defined by the sign of R(i) . There are four kinds of sign composition of U, W
corresponding to four kinds of machining path as Fig. 3-46.
Example: Fig. 3-49, thread M68×6.
