# Question: A critical dimension of a machined part has specifications 100

A critical dimension of a machined part has specifications 100 + –10. Control chart analysis indicates tht the process is in control with x=104 and R = 9.30. The control charts use samples of size n = 5. If we assume that the characteristic is normally distributed, can the mean be located (by adjusting the tool position) so that all output meets specifications?

A process is to be monitored with standard values µ = 10 and σ= 2.5. The sample size is n = 2. (a) Find the center line and control limits for the x chart. b) Find the center line and control limits for the R chart. (c) ...Rework Exercises 6.34 and 6.35 using x and s control charts. The process is out of control on the x chart at subgroup 18. After finding assignable cause, exclude subgroup 18 from control limits calculations: Reconsider the data from Exercise 6.42 and establish x and R charts with appropriate trial control limits. Revise these trial limits as necessary to produce a set of control charts for monitoring future production. Suppose ...Control charts for with n = 4 are maintained on a quality characteristic. The parameters of these charts are as follows and x s Both charts exhibit control. Specifications on the quality characteristic are 197.50 and ...Control charts for have been maintained on a process and have exhibited statistical control. The sample size is n = 6.
