Since the leather materials are used in various industries such as shoes, fashion, furniture and automotive industries, it is essential to introduce laser technology on cutting leathers with intricate geometries under better environmental conditions. In this investigation, an effort was made to analyze the effects of laser power diode on environmental measures such as carbonization, striations and dross formation in leather cutting. It was attempted to compute the optimal factors using TGRA methodology. It was inferred that laser power diode cutting process can eliminate the striations and dross formation on leather cutting due to elimination of mechanical impact energy. Laser power diode can reduce the carbonization effect on leather cutting owing to the lower and concentrated energy. The optimal process parameters combination of laser power diode based leather cutting process was found with tolerance of 4.6%. Standoff-distance highly influences on determining the lower carbonization region and kerf width in laser power diode based leather cutting process.
