Abstract: Micro-grinding is an important processing method in micro-manufacturing field. The theory models of force and temperature characteristics in micro-grinding Al6061 are established. A single factor experiment in micro-grinding Al6061 is designed and carried out. From analysis of experiment results, micro-grinding force and micro-grinding temperature effects with different grinding parameters are revealed. According to different depth of micro-grinding, temperature distribution of micro-grinding surface temperature and the temperature of different depth below the surface are deliberated, and thermal burns on finished surface are detected. The force and temperature models proposed by are also accurately confirmed, the highest surface temperature of micro-grinding Al6061 is up to 78.5 ℃. From the experiment results, important reference is provided for further researching surface integrity and improving surface quality of parts.
