Your shop rate or machine rate as you put it depends on all of the above mentioned plus any maintenance and tooling that machine will require.
If your making your own products and have buyers for those products you can estimate the costs of doing business.
The question you asked has been answered as far as I can see.
Honestly it's your call.
There are shops charging anywhere from $40 to $250 per hour but that rate is determined by the difficulty of the Part, Material Cost, Time to Machine, Insurance, Taxes, Employees, Shop Rent, Utilities, and the demand of the product.
You mention you own the machine, but do you have ALL the necessary cutters, tool holders, fixture material, and hardware too? I stress the word All for a reason. It is pretty hard to have everything for every job if your quoting jobs and you usually have to order tooling and material.
What are you making? Tools, Dies, Die-Cast-Dies, Parts, Assemblies??
What you make has a large affect on what you will have to charge per hour. And even if you estimate it accurately, there are usually a few bumps along the way that one has to be prepared for.
