Monitoring the temperature of the milling process using infrared camera

June 2013

    The study of temperatures generated in machining processes has been the theme of research since the beginning of the XX century. High temperatures can provoke changes in the microstructure of materials, resulting in form errors that may cause loss of the machined material and a decrease of tool life. As a result, high temperatures can be responsible an increase in...
