Estudo dos diferentes métodos práticos empregados para medição da temperatura de corte gerada durante o processo de usinagem por torneamento

Abstract

During the machining of metals, high temperatures are generated in the chip-tool interface. These temperatures, in turn, have a strong influence in controlling the removal rate of material and friction between the chip and the cutting tool. It is noted, however that the direct measurement of temperature in this region is difficult to implement due to the movement of the piece and the presence of the chip. This work aims to study the different practical methods used for measurement of the cut generated during the machining process by turning temperature, determining the temperature field in various regions of the tool, some even inaccessible, realize through experimental apparatus analyzes conducted in some of the methods used at work the importance of each element in the process and describe the use of criteria as well as to assess the various factors that can influence so that the cutting temperature increase or decrease and know which measurement method used in each case particular, to improve understanding of the subject. Some authors rather explore the topic with regards individual analysis, others take into account the importance of computational analysis even to ensure accuracy at the time of the visa currently there are some software that guarantee results not only confidence in the final result but also assist in factors such as dimensional accuracy and maintenance of the microstructure
