Statistical Process
Control is a critical part of tracking performance, and evaluation
of process capability is an important element to track the need to
closely monitor.
Using the table
below and the attached X-bar, S charts, determine the process
capability indices for the process (Cp,
Cpk),
and evaluate whether the process is capable for average surface
roughness (Ra) for the inner diameter of
tubing. If
not, what change(s) should be made next to get
Cpk

Explain the difference between process capability and
statistical control.
Suppose that a process with a normally distributed output has a
mean of 50.0 cm. and a variance of 3.61 cm. If the specifications
are 51.0 +/- 3.75 cm.,
a. Compute Cp and Cpk
b. What are your conclusions about this process?

Statistical process control charts:
A. display upper and lower limits for process variables or attributes and signal when a process is no longer in control.
B. display the measurements on every item being produced.
C. are a graphic way of classifying problems by their level of importance, often referred to as the 80-20 rule.
D. indicate to the process operator the average outgoing quality of each lot.
E. indicate to the operator the true quality of material leaving the process.
