Estudo da influência do operador na seleção da velocidade de corte no torneamento de aços e a consequência na vida da ferramenta

Abstract

Today market competitiveness leads companies, especially those in the area of manufacturing and machining, to seek improvements in their processes in order to survive the disputed competition. Continuous improvement is a concept that appeared precisely from the idea of competitiveness in the market. It consists of a set of actions and procedures to improve the quality of the processes in each company, thus delivering products with lower production costs and higher quality. Many companies, to put the concept of continuous improvement into practice, adopt the philosophy of lean production to reduce waste and increase production efficiency. Thus, the present work was carried out in a medium-sized company in the city of Uberlândia-MG, whose objective was to perform an improvement in the machining process by mechanical turning with human labor, in order to reduce the waste of cutting tools. All work was planned and structured based on the PDCA cycle (plan, do, check and act) using Microsoft Excel ® for data and values organization. With this work it was possible to observe and analyze the main possible causes of the enormous waste of cutting inserts for turning as well as offer solutions to solve the problem.
