Hello, Can anyone help please? I have been setting and operating CNC milling machines for a few years now. I have taken on a new job as a setter operator for a different firm, I can look at a program and understand what the m/c is doing from it what but my own programming is very limited. I was wondering if there is any good CNC simulation software (preferably free) out there as I want to refine my programming skills, but do not always have the time to do it in work.
