A local engineering shop is responsible for producing small metal items (e.g. washers, inserts and spacers) for the hardware industry to supply with nuts and bolts. The following time study details were provided for one of the stamping presses. Element Occasional 1 A B Occasional 2 Occasional 3 Description Load sheet metal strips into magazine (10 strips) Cut metal washer (from strip) Unload metal washer (place in storage bin) Remove offcut material (1 strip) Transport storage bin to warehouse (On completion of 10 strips) Observed cycle Rating Observed cycle Rating Observed cycle Rating Observed cycle Rating Observed cycle Rating 1 13.6 110 0.06 90 0.13 80 0.39 75 10.62 90 2 16.4 90 0.04 110 0.14 80 0.34 100 9.50 100 3 14.8 100 0.05 100 0.16 70 0.40 65 4 15.3 95 0.08 70 85 0.12 0.34 85 The following notes were made on the time study: Fifty (50) washers can be produced from one (1) sheet metal strip The company also indicated that the policy allowance is 5% of basic time.

(8) 1.3 Calculate the new standard time for the process (Use Addendum B) 1.4 If the machine is run for a 9-hour shift each day, determine the output of completed washers for a week, if the company works 5 days per week. (1) The production manager for the engineering shop has approached you to revise the time study. The item produced is currently in high demand and to speed up the process in line with customer demand, the production manager has requested a tool change. The change will allow for the item to be produced on a tool that cuts two parts per cutting stroke instead of the one part per cutting stroke (as above). Assume that the process, material and the process times will remain the same (as above) for all elements and all allowances will remain the same (as above). The tool orientation allows for sixty (60) washers to be produced from one (1) sheet metal strip as compared the fifty pieces from before. (6) Operation Description: Operator Analyst S Ele.
