Fanuc 10m User Manual
Hello All; I purchased a used VMC that has a fanuc 10M control on it. Pretty simple machine but fine for the parts that I am doing.

I have been running it but I am doing something wrong when establishing part zero. The method that I have been using to set workpiece zero is to verify that the machine origin (machine zero) is at zero in the home position, then establish zero on the part and enter the machine origin values into the G54 offset table. If I try to run a part after entering this information, the machine wants to run using the 'absolute origin' values, regardless of how they relate to the G54 position. To solve this problem I have to return the machine to the home position, change to 'absolute origin' and update the values in 'absolute origin' so that they are correct in relation to the G54 zero point. Although this works I am sure that I am doing something wrong. If anyone is familiar enough with this control to understand everything that I have written here, I would appreciate a bit of help from them. I am sure that there is a proper procedure for setting 'absolute origin', 'relative origin' 'G54 offset' etc.
But I haven't been able to fully understand it from the manuals that I got with the machine. Thanks, Glenn McMullin. Metro if I read your post correctly, I understand that you want to see the coordinates in the 'absolute mode' from the G54 offset? X1.00,Y1.00 as opposed to say X20.,Y10(from the machine home) Does you machine allow you to see different values?
On my lathe I can change from machine coordinates, work coordinates, distance to go, and something called operator(which I have never used) Can you toggle between them? Also, (and this is not a fix per se) try running a G92 once you have put the tool over G54 x0,y0. Maybe, that might bring up the coordinates you want to see. I have no doubt that someone here will be able to help you and make my advise seem like that of a 2 year old, but it is all I can think of. Best of luck, Doug. Hello doug; Seeing the coordinates is nice and I can do that by toggling between the different origin screens on the control. I can bring up 'relative' (although relative to what I don't know), 'absolute', 'machine' or all three on one screen with 'distance to go' shown as well.
The problem that I am having is that the machine seems to want to work relative to the 'absolute' coordinates, even though I have programmed G54 at the start of the program before any movements. My manual details how to use G92 very clearly, but then suggests that it is easier to call G54, G55 etc.
Instead of using G92. The proper use of G54, 55 etc. Is not clearly explained however. The 'absolute' zero also seems to have an ability to re-set itself to a number other than what I have preset it to.
I think that I must be presetting the values when in G54 instead of G53 or something like that but I can't figure it out. I know that there must be some logic to all of these different zero's and how they should be used but it is not clearly explained in the manuals that I have. If anyone has a good understanding of this please speak up. Thanks, Glenn.
PS, if you help me with this I will e-mail you a beer. (Canadian one too!). I hope more of you are watching this thread. I have been playing with the machine all day and have noticed a few more clues to the problem. If I eliminate G54 from my program and substitute G92 Xyz, the program starts up correctly, the 'absolute' position readout updates correctly to show the tool position relative to the part zero, the 'relative' position readout shows the distance from current position to home position and the program runs fine. Is there a parameter that can be changed to turn the G54 thru G59 fixture offsets on or off? I am wondering if the previous owner may have been doing some tweaking on his own.
Thanks, Glenn. Problem solved!! Thanks to those who responded. The suggested solutions weren't exactly what was required, but trying them out got me going in the right direction.

It turns out that the values entered in the G54 offset table are only activated correctly when the machine is manually sent to the reference (home) position. I thought that using G28 would do the job properly but it doesn't. This process was outlined in the machine manual but like a lot of technical material, it only becomes clear after you have made all of the mistakes that are possible. Thanks again. Glenn McMullin.
