QUESTION 3 [20] Quality check at every stage is extremely critical to prevent quality problems down the line leading to recalls & reputational damages. The problem with manual inspections - they are costly, time consuming and heavily dependent on human intelligence and judgement. "Automated surface quality inspection" is an image analytics solution based on Artificial Intelligence (AI) that helps overcome these challenges. The solution identifies and classifies defects based on image analytics to enable quality assessment and provides real-time visibility to Key Performance Indicators through dashboards to monitor plant performance. 3.1. Narrate on how you will perform inspection in an organisation that deals with manufacturing a product of your choice using the points of inspection. Give full details, starting with the type of the product you chose. (6) 3.2. A manufacturer of precision machine parts produces round shafts for use in the construction of drill presses. The average diameter of a shaft is 1.40 cm. Inspection samples contain 6 shafts each. The average range of these samples is 0.02. Determine the upper and lower x-control chart limits. (5) 3.3. Twelve (12) samples of n = 200 were taken by an operator at a workstation in a production process. The numbers of defective items in each sample were recorded as follows. SAMPLE Number of defects 1 12 0.060 2 18 0.090 3 10 0.050 4 14 0.070 5 16 0.080 6 19 0.095 7 17 0.085 8 12 0.060 9 11 0.055 10 14 0.070 11 16 0.080 12 14 0.070 Management wants to develop a p-chart using 3-sigma limits. Set up the p-chart and plot the observations to determine if the process was out of control at any point. (9)
