Thanks Russel,
The point of this post is that I did want to use offsets for this program, in order to fault find the system, and they do not work as described in the Fanuc manual.
There is a fault in this Fanuc system as it does put a variable offset into the Z axis, regardless of whether you...
Do not know for the 18T but should be able to pick up the diagnostic (an X input) from the wiring diagram.
If you have the encoder shaft disconnected you should be able to spin the encoder and watch the X diagnostics pages, and see which one is changing.
Usually the info is in BCD, for turret...
Thanks for your posts, it appears that the finishing allowance in the X axis is a TYPO in the Fanuc Manual. There should be NO finishing allowance in X for G70. The Z axis problem is still unclear, Fanuc are still puzzled by this.
Omron have a free software package, for programming cpm series PLCs. You can build a PLC ladder on your computer and the help function explains each operand quite clearly.
If you do not understand something, build it and it becomes obvious as to how each function operates.
The principles are...
Thanks for the replies guys, will post the diagnosis when we get there. So far Fanuc have not shed any light on the matter, still charging my customer $140 per hour to do it.
I am looking for some clues on a problem with a Daewoo 8UHS lathe fitted with a Fanuc OTC-B. Machine works perfectly and is accurate, until canned cycle G70 is called.
If G71(stock removal) is called with 1mm finishing allowance, then part is cut to size + 1mm in diameter and length, which is...
