This is a large (28", 2m BC), older (fanuc 6T) lathe which, due to its long bed, has a movable Z home stop clamping to the front way. It was supplied with a scale running just under the way, now missing, which allowed approximate repositioning of the home stop via a pointer. The scale was removed by a previous owner.
After reading the thread about the possibility of encoders' rev counters reading incorrectly if homed in the proximity of the reading heads, I got worried and informed the boss that presumably the missing scale registered the safe zones as well as aiding positioning. He countered that since the manual made no mention of the subject, our machine might use a different encoding system. I countered that the older Mazak manuals are more like a fill in the blanks game.
He is prepared to listen on the subject, but leaves me to do the legwork
Anyways, after a little research, I don't see any possibility other than I (and my boss) am leaving myself open to a pretty nasty crash at some time due to this problem. My last job was turning 300lb gear blank forgings at up to 300 rpm
Can anyone give me somthing definative on this one?
Cheers all, Vincent
