Cp-spc manual

Statistical Process Control (SPC) Cp (capability process) The Cp index describes process capability; it is the number of times the spread of the process fits into the tolerance www.doorway.rug: manual. Statistical process control consists in a set of statistical tests performed on a process. SPC techniques evaluate the variability of a process, so to identify the probability of non-conformities. SPC is done with the help of QS-Torque software Cp Cm has the same meaning, but Cp is.  · Cp = (USL LSL)/6*www.doorway.ru Ppl/Cpl = (Mean LSL)/3*www.doorway.ru Ppu/Cpu = (USL Mean)/3*www.doorway.ru Ppk/Cpk= Min (Cpl, Cpu) Difference between Cp and Pp indexes are HOW TO CALCULATE THE SIGMA.

Quality data is collected in the form of product or process measurements or readings from various machines or instrumentation. The data is collected and used to evaluate, monitor and control a process. SPC is an effective method to drive continuous. Cp has nothing to do with whether a process is centered. There is no sample mean in the equation! Cp is the ratio of the spec range over the sample std dev. Cp = 1 when they are equal, and can be far greater than 1. Cpk is also =/= 1 just because the process is perfectly centered. In that case, Cpk = Cp.

Statistical Process Control is based on the analysis of data, so the first step is to decide what data to collect. There are two categories of control chart distinguished by the type of data used: Variable or Attribute. Variable data comes from measurements on a continuous scale, such as: temperature, time, distance, weight.
