KE41003/KE00703/KM42103 Industrial Automation Test t S1 (2014/2015) There are TWO questions. Please answer ALL questions. Marks for each question are indicated by the side. Good luck. 1. Define three types of production plant and give examples for each. In a highly classified fighter aircraft equipment plant, a balancing control part goes through 3 different machines. The timing are given in the following Table b. Machine Setup Time(h) Operation TimeNo-Operation Machines used (min) Time (h) in Plant 12.0 The plant needs to meet the batch demand of 100. There are 8 shifts per week with an average of 8 hours per shift due to stringent quality monitoring during process. The plant is open only for 6 days a week. Calculate: (1) Manufacturing Lead time, in hours (MLT) (fi) Day to produce the batch. (i1) Average production rate (R) for Machine A, B &c; (iv) Production Capacity (PC) for Machine A, B & C (v) Explain the machine that plays the vital role in the production (vi) If the customer needs the products in 6 days, based on the current plant [10] [15] [12] [21 settings, explain and show how can this be met? [20] Total marks 68) 2. Draw and explain the different types of Parts feeding device components. 15] A transformer doll is being manufactured in a multi-station assembly with 5 machines. The cycle time is 12s. The probability of defect that will jam the station is 0.35 with the downtime of 60s. The defect rate of each station is 0.01 Determine: (i) Average Production Rate (i) Yield of Good Assemblies (ii) Yield of not Good Assemblies (iv) Uptime efficiency of the assembly machines b. [101 [101 12) (Total marks 32) Page 1/2Explanation / Answer
1)Some of the most important types of production are: (i) Job Production (ii) Batch production and (iii) Mass or flow production
(i) Job Production:
Job production involves intermittent process as the work is carried as and when the order is received. It consists of bringing together of material, parts and components in order to assemble and commission a single piece of equipment or product.
(ii) Batch production :
This method is generally similar to job production except the quantity of production. Instead of making one single product as in case of job production, a batch or group of products are produced at one time. It should be remembered here that one batch of products may not resemble with the next batch.
Mass or flow production:
Flow production is the manufacture of a product by a series of operations, each article going on to a succeeding operation as soon as possible. The manufacturing process is broken into separate operations.
