OPERATION
90
Tool changing position is fixed to the following temporary position which
is not related to the NC parameter No. 1241 (the second reference
position) .
In case of program zero point is workpiece end
X material length +100 (when unit is inch, +10)
Z 150 (when unit is inch, 15)
In case of program zero point is chuck end
X material length +100 (when unit is inch, +10)
Z material diameter +150 (when unit is inch, +15)
In the machining macro program, when Offset data save restore function
is effective and only execute Processing simulation, the program
commands G00 instead of G30 to display the tool at fixed position
however absolute and machine coordinates are any value. Therefore, if
Offset data save restore function is used, the machine tool builder’s
original macro program will be changed in case of G30 is in the macro
program.
G30 U0 V0 → G00 X (material outer diameter +100) Z150
If the change is necessary, please replace the part of calling G30 command
with the subroutine which shows in the follows. Command order of axis,
simultaneous axis number etc. follows G30 command which is replaced
G00 command ( see machining macro program O0450– O0455, O0460)
Command value of each axis in G00 is in order to inputting unit and
program zero point.
In case of program zero point is workpiece end
X material length +100 (when unit is inch, +10)
Z 150 (when unit is inch, 15)
In case of program zero point is chuck end
X material length +100 (when unit is inch, +10)
Z material diameter +150 (when unit is inch, +15)
