Usually, the surface quality of components produced under turning of particle reinforced metal matrix composites (PRMMCs) is one of the most important factors influencing their practical performance. Keeping good surface quality needs additional manufacturing cost or loss of productivity. In this study, semi-finish turning tests were conducted using high-power diode laser and cemented carbide tools to evaluate the superiority of the laser-assisted machining of PRMMCs and better understand its governing mechanism. The Taguchi method is used to optimize the cutting parameters in laser-assisted machining (LAM) by seeking the smallest surface roughness and the best signal-to-noise ratio. The results of orthogonal experiment revealed that the most significant turning parameter for surface roughness was feed rate, followed by the rotational speed, the cutting temperature, and the depth of cut. LAM provides a larger material removal rates under the same surface roughness compared with conventional machining. The tool wear mechanism for coated and uncoated cemented carbide tools was evaluated, and the LAM provides a maximum 2.31 times improvement in cemented carbide tools over conventional machining. Additionally, an economic analysis reveals significant benefits of diode laserassisted machining of PRMMCs over conventional machining with conventional carbide tools.

“…It has already been shown that LAM makes it possible to machine high strength metals like Ti6Al4V [3,4], Inconel 718 [5], graphite iron [6], AISI D2 tool steel [7] or metal matrix composites [8] and ceramics [9][10][11]. For these materials, it improves workability by decreasing the cutting forces and by increasing the tool life.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Laser Assisted Machining (LAM) improves the machinability of materials by locally heating the workpiece just prior to cutting. Experimental investigations have confirmed that the cutting force can be decreased, by as much as 40%, for various materials. In order to understand the effect of the laser on chip formation and on the temperature fields in the different deformation zones, thermo-mechanical simulations were undertaken. A thermo-mechanical model for chip formation was also undertaken. Experimental tests for the orthogonal cutting of 42CrMo4 steel were used to validate the simulation. The temperature fields allow us to explain the reduction in the cutting force and the resulting residual stress fields in the workpiece.

“…In order to increase productivity certain types of 'assistance' can be used to facilitate the cut. It has already been shown that LAM makes it possible to machine high strength metals like bearing steel [1], Ti6Al4V [2,3], boron [4], metal matrix composites [5] and ceramics [6][7]. For these materials, it improves workability by decreasing the cutting forces and by increasing the tool life.…”
