A new method for heat measurement during high speed machining

The cutting temperature and temperature distribution along the rake face of cutting tool and work piece is an essential factor in study of machining processes due to its effect on surface quality, tool life, tolerances, metallurgical behavior and chip-removing rate. Several methods have been introduced to measure temperature during machining, such as the thermocouple technique, infrared camera and metallurgical methods. Each of these methods has some advantages and limitations. In this article, an infrared high-speed sensor with specially designed software has been used to measure the transferred heat to the work piece during high speed machining (HSM) of bronze alloys. The results revealed that this system enhances accuracy and reduces the number of tests required.
