here is an interesting conversation i had via email with some good cnc info in it
we have a retrofit lathe with fanuc 0iTB mate control , we have a new job where we need to make a R8 radii , we are not getting this properly, we got a local programming guy to have a look at our program and he feels it’s ok, do we need to ensure if any parameters are enabled to form radii
The best on hand reference I have found is “CNC Programming Handbook” by Peter Smid. you will find it very informative and broken down into simple terms. Even dissecting Canned cycles.
