Cutting Temperature and Force Data Acquisition and Measuring System Design in High Speed Machining

In order to measure the dynamic cutting temperature in high speed machining, a new method to prepare multi-layer thin film thermocouple sensor on a ceramic tool was presented. the sensor was fabricated on the ceramic tool´s rake face with the technology of magnetron sputtering, lithography, and plasma enhanced chemical vapor deposition (PECVD) methods. The preparation process of the multi-player thin films was expatiated. The high speed cutting temperature and cutting force data acquisition and measuring system was designed. The type of data acquisition card is ADlink PCI-9118HG. Simple and friendly human-machine interface was programmed with the application of VC⁺⁺ technology and Tchart controller to achieve real-time data acquisition, display and analysis of high-speed cutting temperature and cutting force. It was concluded from the experiment that the data acquisition and measuring system is easy and flexible to use.
