Exactly: if the model* from which the data points were taken is successful, and the tooling is properly programmed**, the CNC product will work well. If either of these is not adequate, it won't.

* most common error I've heard of:
Customer: "I have an iron BBM. What castings and chamber volume do you have programs for?"
Shop: "................... What?" He'll use the one he has, even if it's from a different but interchangeable casting (906 vs. 452 etc.)

** running the program from fewer angles or at higher speed gives coarse finish and less accuracy on internal surfaces



Wow... it’s nice to see someone running off at the mouth about a company they have NO experience with. I personally don’t have experience with their heads ether but I have seen them in person and I know TONS of people that do and make big power with them. I also know for a fact that the owner has separate programs for at least 4 different BBM head castings (516,915,906,452etc) rolleyes


If you had read his post before you ran off at the mouth, you would see he wasn't talking about any company in particular and that you actually agree with him, different castings need different programs.
