- Solve the question below- except that availability = 95%. In a sequential batch machining operation, setup time is 1.5 hours, and the batch size is 120 units. The cycle time consists of part handling time of 30 sec and processing time of 2.85 min. One part is produced each cycle. Tool changes must be performed every 10 parts, and this takes 2.0 min.

- Kindly show the complete step-by-step solution. Please make sure that your handwriting is understandable and the picture of the solution is clear. I will rate you with “like/upvote” afterwards. Given Problem: Please see the attached photo.arrow_forwardIn a factory where there are three shifts: The machine overhead cost is found to be £8.20 / hr, the labour overhead cost is found to be £30.20/hr, and the premises overhead cost is found to be £3.50/hr. Using the principle of overhead costing: If a single component takes 23 minutes to manufacture on the milling machine. What is the cost / part? You should include machine costs, labour costs and premises costs in your answer, but you can neglect material and energy costs. Express your answer in £ rounded up to the nearest penny.arrow_forward1. Technician is turning (lathing) a work material with shear strength of 250 MPa as shown in Fig.1.

- An emergency situation has arisen in the milling department, because the ship carrying a certain quantity of a required part from an overseas supplier sank on Friday evening. A certain number of machines in the department must therefore be dedicated to the production of this part during the next week. A total of 1000 of these parts must be produced, and the production cycle time per part = 16.0 min. Each milling machine used for this rush job must first be set up, which takes 5.0 hr. A scrap rate of 2% can be expected. Assume availability = 100%. (a)If the production week consists of 10 shifts at 8.0 hr/shift, how many machines will be required? (b)It so happens that only two milling machines can be spared for this emergency job, due to other priority jobs in the department. To cope with the emergency situation, plant management has authorized a three-shift operation for six days next week. Can the 1000 replacement parts be completed within these constraints?arrow_forwardwhat process is this? how to perform this?
