LAPPING COST MODEL: AN EFFECTIVE TOOL TO CALCULATE FINISHING PROCESS COST
Keywords:
Lapping, Machining cost, Value-based negotiation (VBN), Product Cost ManagementAbstract
In this paper, cost model for the lapping process is developed and used for analyzing the cost involved in this process. Lapping process was studied by means of experiments, literature survey and by visiting suppliers of the lapping machines. The results from the experiments, information from the suppliers and past experiments by the researchers were explored in details and used to develop the relations among potential parameters and to see the possibility of the lapping process cost model development. Cost analysis of the valve plate (a component of axial piston closed circuit pump) is also studied. A comparison between the results and the market price reveals the hidden savings potential in the process.
