Monitoring system in the experimental investigations of the temperature in the cutting process by machiningwith turning (original) (raw)

The development of computer aided research systems, used for experimental measuring of the temperature in the cutting process, forms conditions for decreasing of the measuring uncertainty. This paper describes new monitoring system for temperature measuring in the machining with turning. A method of the nature thermocouple has been used for measuring the temperature. A specially constructed device transmits the voltage signal from the workpiece side and a reconstruction of the cutting insert holder provides the transmition of the voltage signal from the cutting insert. The transfer of the generated thermocouple voltage to the personal computer is done by original interface, which consists of amplifier and A/D converter. An application that was created in Microsoft Visual C++ 6.0 receives the data and displays the curves of the thermocouple voltage that is generated in the cutting process.
