Convert 22C to Fahrenheit.
Us (5-5)' High carbon steel or alloy steel can be used for the set of tools on a lathe. The tools must be sharpened periodically. Data for each are as follows: High carbon steel 60 pcs 4h 1h e Alloy steel 70 рсs 6 h 1h Output per hour Time between tool grinds Time required to change tools The wage of the lathe operator is P50.00 per hour, based on actual working hours. The tool changer costs P60.00 per hour. Overhead costs for the lathe are P45.00 per hour, including tool-change time. A set of unsharpened high carbon'steel costs P500 and can be ground ten times; a set of unsharpened alloy steel costs P850 and can be- ground five times. Which type of steel should be used? Solution High carbon steel: cycle time = 4 + 1= 5 hours number of pieces per cycle Cost per cycle: Operator = P50 (4) Tool.changer = (P60) (1) Overhead = (P45) (5) (4) (60) = 240. %3D P200 60 225 %3D Unsharpened tool = P600 50 Total 10 P535
