description | The feasibility of laser-assisted machining (LAM) and its potential to significantly reduce fabrication costs and improve product quality have been shown experimentally for various ceramic materials. However, no systematical investigation has been performed to expand LAMs capability to parts with complex features, although such capability is essential for industrial applications. This paper presents a transient, three-dimensional thermal model developed for LAM of workpieces with complex geometric features and its validation by in-process surface temperature measurements with an infrared camera. It is shown that the LAM experiments designed based on the predictions by the thermal model successfully produced silicon nitride parts with complex features, thus demonstrating the capabilities of LAM in fabricating ceramic parts suitable for industrial implementation. |
