thanks bob The control is also a 31i not 32i so it should be the same except that it must be set up for a vertical. What you are saying looks like the book is telling and what we have tried, We will try again with your info. We have to inform at the manufacturer how to set the parameters. Do you have an example program, and how did you set up your post.

thanks for your reply, We have the separate page where we can enter 8 dfo,s. Do we have to set the workpiece x,y,z, and c position in there and not use G54 at all. On a horizontal you have a fixed center of rotation where the G54.2 calculates from which was allready set on your machine, but on a vertical we have to set that somewhere in the control and depends on the position of the rotary table. That can be the reason why it is not working in our case yet. Do you have an example program with a few different planes. How do you set the parameters for different views in mastercam to put out G54.2 instead of G54, G55, G56 etc.

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
