A Review on Research and Development of Laser Assisted Turning

LAM(Laser assisted machining) is machining method that performs a machining for workpieces using a laser preheating process. By combining the LAM and CNC lathe using laser beam, it could be named LAT (Laser Assisted Turning). A machining process in LAT has been applied at 1200 similar to 1400 degrees C using a specific cutting tool, after preheating a workpiece using laser beam as about 2000 degrees C. This study performed a review on the laser assisted turning and heat treatment through classifying these technologies into three categories; the device and mechanism for establishing LA T, the machining process and heat treatment for applying LA T, and the analysis and theoretical research, which are the most important issues in LAT.
