Experimental investigation of the effect of cutting tool rake angle on main cutting force
Journal of Materials Processing Technology, 2005 This paper presents a study of the influence of tool rake angle on the main cutting force for machining rotational parts by sharp cutting tools. A special dynamometer was designed and produced to measure the forces for this purpose. Two strain gages were

Summary Experimental orthogonal machining results are given which show that the ratio of the force normal to the cutting direction to the force in this direction increases with decrease in undeformed chip thickness as well as with increase in negative rake angle.

A Study of Metal Flow Ahead of Tool Face With Large Negative Rake Angle
Journal of Engineering for Industry, 1982Although the chip formation mechanism by a tool having a large negative rake angle is not well known, it is very important to make the process clear in order to get high quality in finished surfaces. In this paper, the behavior of material ahead of a tool face with a large negative rake angle is examined by means of low speed machining on lead.

The Application of the Uncorrected Tool with a Negative Rake Angle for Tapered Thread Turning
2019Based on geometric modeling and FEM, it is developed a technique for choosing the values of geometrical parameters of a threaded turning tool (rake angle, clearance angle, inclination angle of the cutting edge). This technique depends on the allowable values of kinematic rake and clearance angles at different points of the cutting edge and reliability ...

Adiabatic shear fracture prediction in high-speed cutting at various negative rake angles and feeds
Advances in Manufacturing, 2018The critical characteristics of adiabatic shear fracture (ASF) that induce the formation of isolated segment chip in high-speed machining was further investigated. Based on the saturation limit theory, combining with the stress and deformation conditions and the modified Johnson-Cook constitutive relation, the theoretical prediction model of ASF was ...

Abstract A comprehensive demonstration of fictional behaviors at the chip-tool interface promotes better understanding about cutting force, stress distribution and heat generation. However, previous attention was paid mainly on the positive rake angle cutting, while the study on large negative rake angle cutting is still limited and challenging due ...
