Evaluation of the cutting performance of micro-groove-textured PCD tool on SiCp/Al composites

The cutting performance of textured polycrystalline diamond (PCD) tools on SiCp/Al composites is studied using an orthogonal cutting experiment. Micro-grooves with rounded corners are machined on the tool. Two texture parameters, namely the distance between the texture and main cutting edge and the texture spacing, were varied to investigate their influence on the cutting performance. The former is found to play a more important role in machining. Compared with non-textured tools, textured tools reduce the cutting force and tool wear, improve the surface quality, and change the chip flow direction to produce an anti-adhesion effect during cutting. To elucidate the cutting mechanism of textured tools, the cutting performance of tools with different micro-groove shapes is numerically studied using the finite element method. The simulation results indicate that a microgroove-textured PCD tool with rounded corners reduces the interaction between the tool texture and chips, and the particles in the interface play a supportive and rolling role between the chip and tool surface.
