Each characteristic has a name of up to 14 characters 8 if downloaded from a PC Auditor DC can store up to 48 different characteristics at any one time This is a capability index which shows the process capability potential but takes no account of how centred the process is This is used for capability studies and Cp may range in value from O to infinity A large value indicates greater potential capability and a value of 1 33 or greater is desirable Max Min Cp 6 Max and Min are limit values This is an index which indicates whether the process will produce units within the tolerance limits If the process is centred on the nominal value then CpK will have a value equal to Cp For values of CpK between 0 and 1 then some of the 6 sigma spread will fall outside tolerance limits but for values greater then 1 these will all be within tolerance A negative value of CpK indicates that the process mean is outside tolerance limits A value of 1 33 or greater is desirable Max _ Min CpK lesser of 3 or 3 Max and Min are limit values This is an alternative capability index requiring a minimum of 30 readings to be taken In this implementation 5 sub groups of 6 samples are used for each calculation The CAM calculation uses the following formula Max_ Min x Cam Factor 6 x Average Sample Value CAM Factor is taken from a table in the case of 5x 6 samples 1 910 Torque transducer with no coding links but in
