1 In a system featuring two–path NC (TT) and loader control,
a two–path waiting M code functions as a waiting M code for
tool posts 1 and 2.
If a waiting M code is included in a loader program, it is
processed as a general M code.
2 The two–path waiting M code differs from other M codes in
that the code signal and strobe signal are not output.
3 The three–path waiting M code differs from the two–path
waiting M code in that the code signal is output. However,
the strobe signal is not output and FIN processing is
If the settings made for the CNC and loader are different, a
correct wait cannot be performed. While one waits for an M
code, the other processes the M code as a general M code.
When the playback option is selected, the TEACH IN JOG mode and
TEACH IN HANDLE mode are added. In these modes, a machine position
along the X,
Z, and Y axes obtained by manual operation is stored in
memory as a program position to create a program.
The words other than
X, Z, and Y, which include O, N, G, R, F, C, M, S,
T, P, Q, and EOB, can be stored in memory in the same way as in EDIT
Procedure for Creating Programs in TEACH IN Mode
