OK Lets look at the resolution and expected accuracy. This tells me that he is working on extreme detailed parts. AND the time to run tells me it is an expensive part.
I have never seen a machine cutting a finish cut at that resolution that IF you did a feed hold you would not mar, ding, scratch, gouge a finish cut.
Also With certain Material you cannot interupt a cut and have the bit rub the same spot it creates a hard spot which will never finish cut correctly
NOw as the outage events are random we have to assume the worst case senario, it is in a finish cut mode. Experiance tell us IF you plan on the worst case senario the rest will take care of itself(;-)
Try it and you will see what I mean.
OK I'll ignore all of the above because these are the very reasons for my suggested approach. Did you read it?
The only way out would be to RUN continuously or wait FOR a point in the program that the bit is NOT cutting material.
More or less what I've proposed. Did you read it?
That could be hours into a long program. The only way to be absolutly sure is to STOP in a tool change senario. OR use built in hold routines throughout the program AND the programs may not HAVE either.
could be? - may not? - try asking the OP before you right things off. I've always found that an analysis of the problem usually precedes the selection or otherwise of possible solutions - just me from years of software engineering
The only way out would be to RUN The generator is just a replacement for a large battery bank same thing only different name. Still a stored energy source(;-) He mentioned a UPS so they need a battery and it is EASY to add more capacity, add more batteries. LONG outages yep he has the answer UPS and a backup generator
You only know this because I asked - it was only a few posts ago you ASSUMED it was capacitor based and had less than a second of capacity. Like I said - ask some questions of the OP.
Now from past Power company Power Quality Tech experiance
Ah Terry - is there any job you havn't been an expert in?
As to the stop restart part that would very simple to do ONCE you have the machine stopped. We do that all the time in plasma to stop and check the consumables in long cuts. There is a routine to start restart on this forum somewhere that we use to do it.
One minute you're on about the need for extreme accuarcy and the next your quoting me PLASMA?
That is just my experience in outage recovery technics, Your mileage may vary (;-)
There's clearly no limit to your expertise. I'll get back in my box - Over to you Terry for finding the solution for the OP.
