Rationalization of Polymer Composite Materials Processing by Improving Production Efficiency

AbstractEconomic efficiency is one of the main criteria in the design of technological parts processing. To determine this criterion we have identified the main production expenses, including the cost of the cutting tool, the cost of its training, workers’ wages, energy and materials costs. Cost values were obtained for different process parameters. The parameters of the process were the cutting conditions, structural and technological characteristics of cutting tools, as well as the properties of the material being processed. On the basis of the calculated data and the results of conducted experimental studies rationalization of process parameters was performed. It is possible to increase the economic efficiency of the machining of polymeric composite materials by the example of milling fiberglass. The research found that the dependence of the resulted expenses of the cutting conditions has an extreme character, where the minimum point shifted upward cutting conditions by increasing production. According to the research recommendations for the purpose of cutting conditions were developed, ensuring minimal production expenses
