RE: [mfg-smartcam] R levels

[Michael Senack]

The good old Cincinnati’s from the late 70’s to early 80’s. The 7VT, 10VC, 10HC, CIMEX-3 and CIMEX-720 with their P’s and Q’s vector comps and their incremental Z depths. If my memory is right the older Cincinnati’s used G codes to turn comp on and off, left or right and on angles?   -----Original Message----- From: Benz H.

Case in point our Cincinnati's the "R" plane is always programmed to the level of the top of the hole. The machine stays .100" away by default. The "Z" move is then always incremental from the "R" plane and assumed to be minus (it won't drill up away from the part like a Fanuc even if it is unsigned).

Why would you want to have an R level of 0.0 on any tool? This leaves no room for error when the operator decides to adjust the depth .050. Drill's don't like slamming into the part before the cut. I do programs with over 60 tools and many differant R levels and don't have a problem with it. Is this a new practice that I've not heard of in my 25 years of machining?   Jeff
