= Three parts are assembled in series so that their critical dimensions xz, xand xz add. The dimensions of each part are normally distributed with the following parameters: 4 = 50, 0, = 4, My = 65, 02 = 5 and uz = 85, 03 = 7. If the assembly specification is 200 + 30, determine C, and Cpk. Assess whether the process is capable. What percentage of product will fall outside specification? 10 marks Two parts are assembled as shown. The distributions of x, and x, normal with 4 = 40 and 4z = 39.2, and 0, = 0.5 and 0,= 0.6. The specifications of the clearance between the moving parts are 0.9 +0.7. What fraction of the assemblies will fail to meet the specifications if assembly is at random? X1 X2 9 marks Explain the term Precision Tolerance ratio in relation to a measurement system. Your answer should include a description of what the term measures, what it means in relation to the measurement system. 6 marks
