A Numeric Investigation of Rectangular Groove Cutting with Different Lateral Micro Textured Tools

Micro textures on the tool rake face facilitate to improve friction conditions at the tool-chip interface, and therefore contribute to decreasing cutting force and cutting temperature. Literature has shown that lateral textures (perpendicular to chip flow direction) on tool rake face have better performance than other texture patterns. In this present study, the effect of different lateral micro textures on cutting force, cutting temperature and chip formation were analyzed via an advanced finite element analysis code in rectangular groove cutting processes. Three cutting tools with different lateral micro textures on tool rake face, one is parallel textured (MT1) and two are non-parallel textured (MT2, MT3), were employed in this study. The results indicate that lateral textured tools have significant advantages in terms of controlling chip curl, reducing cutting forces and decreasing cutting temperature. Synthetically, asymmetrical lateral textured tool MT2 show best performance in chip breakability control, decreasing cutting forces, and lower mean cutting temperature along the main cutting edge.
