Method for improving the efficiency of products from polymer composites
Improving the quality of treatment is possible by selecting rational parameters of the process of machining and design characteristics of the cutting tool. However, this requires a lot of laboratory and theoretical studies, which often is not of economic benefit to produce. An important problem is to increase the process efficiency of the blade machining of composite materials. To solve this problem, it is necessary to develop a methodology for performance measurement that takes into account design features of the instrument, its efficiency and cutting conditions that allow optimizing the production process. Economic efficiency is one of the main criteria in the design of a technological parts processing. To determine this criterion the main production expenses, including the cost of the cutting tool, the cost of its training, workers' wages, energy and materials costs are identified. The values of the resulted expenses for different parameters of the technological process are obtained. The parameters of the process are 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 experimental research carried out rationalization of the process parameters in order to increase economic efficiency machining of polymeric composite materials on the example of milling fiberglass. Research found that the dependence of the resulted expenses of the cutting conditions is an extreme character, where the minimum point shifted upward cutting conditions by increasing production. According to the research the technique of determining the reduced costs, derived mathematical relations tool life of the cutting tool of the cutting conditions is developed and recommendations on the appointment process parameters, ensuring minimal production costs, are drawn up.
