Hello everyone, I am a mastercam mill level 1 user for several years now and using the search function once in a while but could not find the information i need. So here are my questions. We have a new vertical machining center with 4 th axis The machine is a Hartford HCMC-2082 with fanuc 32i with the G54.2 rotary table dynamic fixture offset ( rtdfo ) function. We are trying to get this function to work but we have no experience with it, and the machine seller doesn't either. The fanuc book also is not very clear. I have read that ithe function is used a lot on horizontal machines, but can it also be used on a vertical machine with the 4th axis when the parameters are set ? Does it use G28 which is on a horizontal machine in the center off the table i think, but on a vertical machine the G28 is a fixed position not in the center of the table so is this a problem. What must be set in the G54 page and what must be set in the G54.2 page on the control. Where do you have to set the workpiece coordinate ( G54 ? ) and where the center off rotation ( G54.2 ? ) We have tryed with G10 L21 Pn P and that does fill the x y z and c coordinate from the program in the rtdfo page on the control. May be a example can make things clear. When we know how the function works we want to use it with mastercam in the MPMASTER post, or is this to complicated. Is there a working fanuc post from mastercam or inhouse or somewhere else. Any help will be very much appreciated. Regards Richard
