I am not a machinist or programmer, I am in the IT department in a support position, so I may not know the proper terrminology.
We have a Hitachi-Seiki mill with a Fanuc controller. It is an older machine and I don't know a lot of details. The operator puts 12 in as his feed rate, but when the machine is doing X-Y-Z moves in 3D milling the displayed feed rate flucuates and drops as low as 0.5. Is this normal operation of the machine or are there parameters or G codes to use to set the machine to use a constant feed rate?
Thanks for any help.
