Good luck.

‘Process velocity’ – what a joke: the world’s gone mad!

Bob,I don’t think this is correct. The OD is set by the position of the end stop.Flat distributions have nothing to do with saw tooth tool wear, it is due to the use of a single first off.

What has tool wear got to do with maintaining all diameters or lengths in the parts within the properly developed process tolerance zone specified?I don’t know anyone who sets up a lathe machine time! Tool wear has nothing to do with the diameter of a part only the cutting speed.

Bob,I’ve been trying to follow this thread. I don’t understand why tool wear or real time measurements are important. When I use a lathe, I just cut until I reach the end stop. When it takes too long or it doesn’t cut cleanly, I sharpen the tool.
