A lot of micro machining has been reported in seeking for best condition and attempts in revealing new methods and materials. Tool size and contact surface became smaller as the materials have excellent mechanical properties and parts produced are in micro size level. In studying the processing parameters and their effects to processing characteristics, temperature measurement is crucially important. However, limited size of working area and temperature changes time frame has lemmatized the applicable temperature measuring tool. This study demonstrates an alternative method in obtaining and validating work piece temperature distribution irradiated using pulsed wave laser in Laser Assisted Micro Milling (LAμM).
