Calculate the process capability based on cp assuming lsl


An alignment slot in a manufactured part has a specification of 2.04 plus/minus 0.02. Data were collected over a 5-day period with samples of size 4 taken each day to set up control charts for the process. The X bar control chart is found to have the following characteristics: UCL = 2.058, CL = 2.042, LCL = 2.026.

(a) Calculate the process capability based on Cp, assuming LSL= 2.02 and USL=2.06. [Hint: can be estimated from UCL or LCL]

(b) Calculate the process capability based on Cpk, assuming LSL= 2.02 and USL=2.06.
