Tool Life in High Speed Turning with Negative Rake Angle
Advanced Materials Research, 2011 The present work studies some aspects of turning process applied on mild steel using cermets tools at high speed cutting (1000mm/min) by using negative rake angle (0 to-12). The influence of increasing the cutting speed and negative rake angle on flank tool wear, cutting forces, feeding forces and tool temperature were analyzed.

The critical negative rake angle of negative rake angle tool is the critical criterion for the state of cutting and plowing in micro-cutting. It affects the flow characteristics of cutting material, the deformation state of chip, the quality of the machined surface, and the amount of tool wear. Meanwhile, a stagnant region often appears in front of the

Extreme negative rake angle technique for single point diamond nano-cutting of silicon
Precision Engineering, 2001Experiments were conducted to evaluate cuts made with the rake face of the tool and the clearance face. The technique involved cutting in the corresponding opposite directions, i.e., forward with the rake face and backward with the clearance face. Cutting of single crystal silicon with both the rake and the clearance face resulted in a smooth ductile ...

Since the uncut chip thickness is comparable to the cutting edge radius, in fact, micro cutting is a negative rake angle cutting process. The minimum chip thickness has great effect on the cutting process. This paper presents an experimental investigation of specific cutting energy and surface quality based on the negative effective rake angle in micro

Adiabatic shear in chip formation with negative rake angle
International Journal of Mechanical Sciences, 2005The mechanics of chip formation in grinding is investigated based on thermo-elastic-plastic finite element simulations of orthogonal cutting with a large negative rake abrasive-grits. The modeling is coupled with temperature and strain-rate-dependent flow stress characteristics of a work material SK-5 (0.93%C carbon steel). The shape of chip calculated
