What you are asking is impossible to answer. Too many variables, every job is different. I try to get US$80/hour for machine time. Sometimes I do better, sometimes I don't quite make it. On a 1 off or very short run, you need to charge for setup time. On a longer run, maybe you can just bump the part price a bit to cover the setup. I normally charge fixtures as a separate charge, a one time set up charge.
Sometimes you can only charge what the job is worth rather than by the hour. If you have a good customer and they need a quick project, then maybe you take a bit less / hr just to make them happy. Don't forget to add in tooling and shipping on the materials.
I figure if I get only about one job out of three, then I'm right in the ball park on price. Many times someone is going to under bid you on a job, that's fine. If you can't make money on a job then you don't want it. Don't underbid, you will lose money.
