3.6.2 Tool function (T function)

The tool function has various command designation types. For details, refer to the

instruction manuals published by the machine tool builder .

3.6.3 Miscellaneous function (M function)

The miscellaneous function is specified by a maximum of a three-digit number

(Mjjj) following address M. With the exception of specific M codes, the func-

tions of M00 to M89 codes are defined by the machine tool builder. Therefore, for

details of the M code functions, refer to the instruction manuals published by the

machine tool builder.

The M codes specific to the NC are described below .

M codes relating to stop operation (M00, M01, M02, M30)

When an M code relating to stop is executed, the NC stops buffering. Whether

spindle rotation, coolant discharge or another operation stops in response to the

execution of such an M code is determined by the machine tool builder. For details,

refer to the instruction manuals published by the machine tool builder. For these M

codes, a code signal is output independently in addition to M2-digit BIN code.

M00 (program stop)

If M00 is specified during automatic operation, automatic operation is interrupted

after the completion of the commands specified with M00 in the same block and

the M00R signal is output. The interrupted automatic operation can be restarted by

pressing the cycle start switch.

M01 (optional stop)

If M01 is executed with the optional stop switch ON, the same operation as with

M00 is executed. If the optional stop switch is OFF, M01 is disregarded.

M02 (end of program)

M02 should be specified at the end of a program. When M02 is executed during

automatic operation, automatic operation ends after the commands specified with

M02 in the same block have been completed. The NC is reset. The state after the

end of a program varies with each machine. For details, refer to the instruction

manuals published by the machine tool builder.
