Control charts for X̅and R are maintained on the outside diameter of a shaft.The subgroup size is 04. After 20 subgroups ∑ X̅= 43.75 and ∑R = 0.286. The specificationof the product is 2.15±0.02 unit. Products falling above and below the specification limitare rejected. The process is statistical controlled and normally distributed. Find the controllimits for X̅and R charts, Process capability, RPI of the process and % rejection. How toreduce the % of rejection if any?
An acceptance sampling plan has lots of 500pieces and a sample size of 60. The number of defects in thesample may not exceed 2. This plan, based on an OC curve,has a probability of .57 of accepting lots when the incominglots have a defective rate of 4%, which is the historical averagefor this process. What do you tell your customer the averageoutgoing quality is?
Design specifications require that a key dimensions on a product measures 346=12 units . A process is being considered for producing this product has a standard deviation of eight units. The process average has been shifted to 350 so that the process capability is 0.3333. Approximately, what percentage of items produced will be defective?

- What is the effect on the cost of quality to the customer when in an agreement with a supplier to ensure all parts are within tolerance before shipment? My answer: Prevention and appraisal costs will increase while internal failure costs can either increase or decrease and external will decrease.arrow_forwardA manufacturing company has been inspecting units of output from a process. Each product inspected is evaluated on five criteria. If the unit does not meet standards for the criteria, it counts as a defect for the unit. Each unit could have as few as zero defects, and as many as five. After inspecting 2,000 units, they discovered 33 defects. What is the DPMO measure for this process?arrow_forwardWe have taken 12 samples of 400 book pages found the following proportions of defective pages: .01, .02, .02, .00, .01, .03, .02, .01, .00, .04, .03, and .02. A page is considered defective when one or more errors are detected. Calculate the control limits for a p control chart. A new sample of 400 pages is taken, and 6 pages are defective.

- A manufacturer receives shipments of several thousand parts from a supplier every week. The manufacturer has the option of conducting a 100 percent inspection before accepting the parts. The decision is based on a random sample of 15 parts. If parts are not inspected, defectives become apparent during a later assembly operation, at which time replacement cost is $6.25 per unit. Inspection cost for 100 percent inspection is $1 per unit. a. At what fraction defective would the manufacturer be indifferent between 100 percent inspection and leaving discovery of defectivesu ntil the later assembly operation? b. For the sample size used, what is the maximum number of sample defectives that would cause the lot to be passed without 100 percent inspection, based on your answer to part (a)?arrow_forwardDesign specifications require that a key dimension on a product measure 105 ± 12 units. A process being considered for producing this product has a standard deviation of four units. a. What can you say (quantitatively) regarding the process capability? Assume that the process is centered with respect to specifications. (Round your answer to 4 decimal places.) b. Suppose the process average shifts to 98. Calculate the new process capability. (Round your answer to 4 decimal places.) c. What is the probability of defective output after the process shift? (Use Excel's NORM.S.DIST() function to find the correct probability.
