How to determine a machine capability? Measuring results for only one shaft

[suzi]

I'm trying to determinate a machine and process capability and I have those questions. Can I determine a machine capability measuring only one shaft with a plenty of processed surfaces, then each surface has its own fit tolerance, becouse of its cylinderity? If I can should I consider all fit tolerance measuring results for only one shaft? Or should I consider MIN and MAX measured fit tolerance for a plenty of shafts?
Is it better for the process control to use XR ratio or Xs ratio?
