A given machining operation is being performed and managements wants to know the cost for performing the work. The information you’ve collected shows the following: Machining Time = 7.680 min., Part Handling Time = 2.650 min., and the Tool Change Time = 15.535 min. The tool requires changing every 585 work pieces and the cost of the cutting tool is $100.75 per tool. The hourly rate for performing the machining and handling within the operation is $118.84 per hour. Determine the total cost required to perform the operation per part.
Given:
machining time=7.68 min
Part handling time=2.65 min
tool changing time=15.535min , hourly rate for perform operation =118.84$/hr
since cost of changing tool is not given, assuming cost of changing tool=118.84$/hr
so cost of performing machining and handling operation per part = (7.68+2.65)*118.84/60
=20.46 $
cost of changing tool per part= tool changing time*cost of tool changing/60/total workpieces requiring tool change
=15.535*118.84/60/585
= 0.0526$
cost of cutting tool per part= cost of cutting tool/total workpieces
= 100.75/585
= 0.1722 $
Total Cost=cost of cutting tool per part + cost of changing tool per part + cost of performing machining and handling operation per part
= 0.1722+ 0.0526+20.46
= 20.684$
total cost per part= 20.684 $
