Friends,
Recently after commissioning a cnc with oi-TC controller we had G78 Threading cycle problem.
While machining after few passes the spindle was stopping and the tips were breaking.Later we found that there was some G-CODE missing in the program like G90,G53 and G97.
Following is the G78 threading cycle program.
Any mistake pl identify them.
G90 G53 T0505:
G97 S500 M04:
G0 X135.0 Z20.0:
G0 Z5.0 M07:
G01 Z20.0 F1.0:
G78 X132.6 Z-25.0 F4.233:
X132.4:
X132.2:
X132.0:
X131.8:
X131.6:
X131.4:
X131.2:
X131.0:
X130.8:
X130.6:
X130.4:
X130.2:
X130.0:
LIKE THAT
UP TO X128
AND FROM X128.0
X127.95:
X127.9:
X127.85:
X127.8:
X127.767:
G0 Z20.0 M09:
T0000
G0 X0 Z110.0 M05:
M01:
Similarly while doing internal threading cycle with g78 after few passes the tool is digging.
IAM NOT FAMILIAR WITH PROGRAMMING SO PL HELP ME.
Thanks
