Abstract

Laser assisted micro milling (LAMM) is one of the techniques used to enhance the ability to manufacture microscale products. Laser is used to preheat the workpiece materials prior the machining process. Compared with conventional machining, LAMM is a green manufacturing method due to reduction in cutting force during machining process. However, it needs to be controlled to avoid the melting and changing of materials properties. Determining the processing parameters and their effects on the processing characteristics, temperature measurement and the laser spot-tocutting tool distance are crucially important. In this study, finite element analysis using ANSYS software was used to predict the heat distribution to characterise the melting and heat affected zone formation. The data at the centre of laser spot were recorded to obtain the appropriate distance between laser spot-to-cutting tool. From the results, the estimations of laser spot-to-cutting tool distance of Inconel 718 together with the allowable depth of cut were determined and applied in the actual LAMM experiment. Meanwhile, the analyses of cutting force and tool wear as an evidence in conjunction with the laser heating application to reduce the materials strength were performed.
