First off I have essentially zero CNC experience, I am trying to get a new machine our company bought running and no one is familiar with it's programming nor does anyone want to really try.
It is an Eguro Nuclet-10 with a fanuc 3T, probably 20 years old I really don't know.
So I downloaded a sample program for a 3T off of smartcam's site and keyed it in. It is supposed to turn down some stock leaving a bolt head, then drill it and then thread it. The sample had inputs at the threading part for 'D' and 'E', but those letters aren't even on the control. I think this control uses 'P' and 'Q' for threading so I used them and it appears to work.
My issue is I cannot figure out exactly what the numbers behind them do.
I've run that section about 100 times slightly changing the numbers and watching and recording the results and have learned a little.
It seems 'P' takes 4 digits and those digits tell the machine how far out from the root diameter to begin threading. Each digit after 'P' corresponds to the same digit after the decimal place of the root diameter, so that is working out when I leave 'Q' constant and just change 'P'.
But when I left 'p' constant and started altering 'Q' I was getting lost.
I did some research that said 'Q' tells the machine the minimum depth of cut per pass, but it didn't seem that way when I ran it over and over.
It seemed to almost do the same thing as 'P' and it varied how far out the tool went before making it's first cut. If I reduced "q" enough it would basically start so close to root it would only make one pass.
I bought a manual online and it says Nuclet-10GL and does not really explain this at all, so I think maybe it's for a slightly different machine.
Like I said, I have no experience with cnc's and I'm trying to make this my project since nobody else wants it and then I can make myself more valuable if I ever get good at it, so I apologize if some of these questions sound really basic and stupid. I just can't get anywhere doing regular internet searches.
