Turning with shallow cuts at high speeds
Bureau of Standards Journal of Research, 1929 Abstract In this paper a method is described for testing lathe tools under shallow cuts and fine feeds. The relations are determined between the cutting speed, feed, depth of cut, and tool life for carbon and high-speed tool steels. Comparisons are made of tools of different forms and of tool life when cutting dry and with water or lard ...

Experimental study of coated carbide tools behaviour: application for Ti-5-5-5-3 turning [PDF]
, 2011 The goal of this paper is to study the relation between the input data (conditions and geometry of cut) and answers (wear of tool, forces and cutting temperatures) when machining the Ti-5-5-5-3 alloy treated. This study has shown that the cutting process

Influence of cutting speed and feed on burr formation
, 2022 S.340-346Current results show that there is no practical, suitible, basic approach for estimating and characterizing burr formation. Especially for high speed cutting, several key issues, such as tool wear, influence the friction, residual workpiece ...

Behavior of Cutting Heat in High Speed Cutting.
Journal of the Japan Society for Precision Engineering, 1998 (1) 切込みや逃げ面接触長さを変化させることにより, 切屑, 被削材, 工具への切削熱の流入割合を求めることができた.(2) 切削熱の切屑への流入割合は, 切削速度の上昇とともに増加し, 被削材, 工具へは減少していく.(3) 高速切削になるにつれて, 逃げ面での摩擦による発熱は無視できなくなる.

Investigation of Cutting Tools and Working Conditions Effects when Cutting Ti-6al-4V using Vegetable Oil-Based Cutting Fluids [PDF]
, 2015 Power consumed in metal cutting is typically converted into heat near the cutting tool edge. Cutting fluids are then provided to a cutting zone in order to improve the tribological characteristics of machining processes and to dissipate the generated ...
