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?
Answer to relevant QuestionsA 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. The control chart parameters are as follows: (a) Estimate the mean and standard deviation of the ...
