It has become very important to develop an in-process monitoring system for machining environment to materialize fully automated and unattended machining. Various monitoring systems have so far been proposed by different researchers. However, most of the systems are not yet effective for practical use except those of AE and piezoelectric types. A new in-process monitoring system for machining environment has, therefore, been proposed which is based on heat flux sensing. Heat flux can be expressed as a time derivative of temperature, thus, this is more sensitive to the variation of temperature. It can be expected that the sensing of heat flux is suitable for the recognition of the machining environment. In this paper, the in-process monitoring of the tool wear has been tried to estimate the potential of the proposed method. The results of actual cutting tests ascertain that the output signal of heat flux sensor is useful and effective for in-process monitoring of tool wear.
