Machining optimization of Nimonic 80A valves

Resumo

The optimization of production conditions was one of the basics objectives of manufacture industry. The choice of the tool for one determined operation and the correct determination of the machining conditions, represent an important factor in the metals working, being this determinant for the evolution of tool-machine and cutting tools. Such fact accents in the serial manufacturing, where divergences in the choice of the cutting speed and the tool may cause notables variations in manufacture costs. The metals machining is a complex process, and the complexity involves a variety of operations and materials.. The decisions for tools selection, machining parameters determination and tool exchange times are carry by process planners, programmers and machine operators in different periods of manufacture. This share of responsibility and the lack of interaction with the process have difficult very the taking of decisions of a form optimized in relation to the tool rack and the process in itself. The considered work aims at to promote the optimization of the machining processes in turning in a manufacture cell, of automobile parts factory, using for this optimization methodology of the process based on the maximum production condition, through the determination of the coefficients of the Taylor equation of tool life in shop floor environment. The objective is to provide to real increases of productivity and quality in industries, without the necessity of investments in new means of production, and valuing the use of the information inside it productive system. The adopted methodology showed itself very practical, because the results were obtained without cause the smallest upset to the productive process.
