Fluidos de corte: tipos, funções, seleção, métodos de aplicação e manutenção nos processos de usinagem

Abstract

During the machining process, the removal of the material by the cutting tool penetration into the workpiece causes heat generation in the region tool-chip because of the occurrence of friction, plastic deformation and of workpiece material, which can cause unsatisfactory results in the product and cause the increase in production cost. Thus, cutting fluids have become fundamental in machining processes are because of your capability to minimize the heat generated and moreover, the demand for cutting fluids has increased considerably due to advances in technology that have provided an improvement quality of it. This study aims to present a bank of information relating to the matter "cutting fluids" involving its various types that can be found in solid form as molybdenum disulfide in liquid form as oils and solutions and in gaseous form as air tablet. They are also placed on the agenda the most varied functions of the fluid in which predominate cooling and lubrication responsible for the decrease of the heat generated in the process. Still presents a selection of fluids that surrounds various specific process parameters and methods of application and maintenance that can increase the operation efficiency and reduce costs and minimize problems related to health and the environment
