Analysis of critical negative rake angle and friction characteristics in orthogonal cutting of AL1060 and T2 [PDF]

Science Progress, 2020
The stagnant region often appears in front of the tool cutting edge, which is caused by mechanical inlay and excessive pressing in plastic metal cutting with large negative rake angle tools at a low speed.

Investigation of the effect of rake angle on main cutting force

International Journal of Machine Tools and Manufacture, 2004
Abstract This paper presents a study of comparison of empirical and experimental results for main cutting force during machining rotational parts by unworn cutting tools. A dynamometer was designed and produced for measuring the forces. Two strain gauges were placed at the correct position on the machine tool and cutting tool at the design stage ...
