Facing SiCp/Mg metal matrix composites with carbide tools

Hybrid Reinforced Magnesium Matrix Composites (Mg/Sic/GNPs): Drilling Investigation

“…Micro-cracks formed due to the strain hardening of the matrix material (Mg). Generally, the performance of coated drill bits is better compared to the uncoated drill bits at the different feed rates and cutting speeds used in this investigation study [6,19]. However, coated drill bits show the smoother machined surfaces, and uncoated drill bits present additional BUE than the coated drill bits, which participate to coarsely-drilled surfaces.…”

Ultra-precision turning of electroless-nickel: Effect of phosphorus contents, depth-of-cut and rake angle

“…The specimens (denoted as (2) in experiments, only one of the above parameters was varied while others were held constant to observe the effects of variation of an individual input parameter on the output parameters.…”

“…However, the main weaknesses of aluminium alloys are their poor high temperature performance and wear resistance. To overcome these problems, aluminium alloys reinforced by ceramic particles, known as metal matrix composites (MMCs), have been developed [2][3][4][5][6][7][8][9]. Nevertheless, the incorporation of the hard particles makes the machining of MMCs difficult [10,11], and diamond tools are often necessary [8,[12][13][14].…”

Prediction of 3D chip formation in the facing cutting with lathe machine using FEM

“…Most of published studies concerning on cylindrical turning despite there are some the other process cutting on a lathe i.e facing, threading, grooving, cutting off. Research on facing cutting (face turning) in experimental has done with by some researchers to investigate the performance of lathe machining process [1][2][3][4][5]. It starts from mild and alloyed steel material [1] then growing very fast on machining metal alloys [2] and most recently using of manufacture part material such Metal Matrix Composites [3][4] and Powder Metallurgy steels [5] The Johnson-Cook plasticity model is used to simulate the cutting process in lathe machining.…”

“…Many researchers have been simulated Orthogonal cutting with the use FEM simulation by using the Johnson-Cook plasticity model. Most of them were investigated tool wear, cutting force, temperature, heat transfer, deformation tool or workpiece material, chatter vibration during cutting process in lathe machining [1][2][3][4][5][6][7][8]. The HSS tool material was simulated where the model used in [6] for analysis bending occurring on material C1060 cutting process under constant conditions.…”
