We pay lip service to DFM, and in my capacity as CNC programmer in the prototype shop, I try to address DFM issues as they come up in the parts I am asked to make. Most of the designers are receptive to my suggestions, but frequently there are design requirements which make DFM difficult to implement. I think a big problem is that few engineers and even fewer marketing professionals have much experience in an actual hands on manufacturing environment. We have development project managers who have no clue what it takes to machine a part.
