Abstract:
Poor machinability of
Al2O3
particle reinforced aluminum matrix composite (Al2O3p/Al) leads to severe tool wear with conventional mechanical machining methods and makes it difficult to ensure fine surface quality and efficiency. In order to solve this problem, laser-assisted hot machining method (LAHM) is adopted in this contribution to study the cutting of
Al2O3p/Al. Good machining results are achieved by optimizing cutting and laser parameters, in which the cutting forces especially radial and axial forces are reduced by nearly 50%, tool wear is reduced by 30% and fine surface is attained. Detailed analysis and study are presented and a cutting process physical model is set up in this contribution which acts as theory fundamental of the research.
