Influence of Cutting Angle on Temperature Distribution of Cutter
Shiyou jixie, 2021 The failure of cutter is closely related to cutting temperature, and the formation of cuttings has an impact on the performance and life of cutter. This article builds a rock-breaking mechanics model to conduct numerical simulation analysis on rock ...

Depth of proofs, depth of cut-formulas and complexity of cut formulas
Theoretical Computer Science, 1994 The standard cut-elimination procedure for classical predicate logic is modified to make alternation of quantifiers (rather than the number of quantifiers) the main complexity parameter.

An Experimental Study on the Depth of Cut of Granite in Abrasive Waterjet Cutting
Materials and Manufacturing Processes, 2011 Many studies investigating the cutting performances of waterjets for several kinds of materials such as steel, brass, glass, or aluminium are available. However, there are few studies focused on the rock cutting in the literature. In the present study, therefore, it is aimed at investigating the cuttability of granite by abrasive waterjet.

The Ratio of Feed to Depth of Cut in Metal Cutting
Journal of the Japan Society of Precision Engineering, 1962 When a metal is cut simultaniously by end and side cutting edges of a tool with the back rake angle i and side rake angle λ, the chip flows to a definite direction determined not only by the rake angles, but also by the ratio of feed to depth of cut.The optimum chip-flow direction of minimum energy can be controlled by choosing the ratio of feed to ...

Cutting Behavior of Cortical Bone in Different Bone Osteon Cutting Angles and Depths of Cut
Chinese Journal of Mechanical Engineering, 2022 Abstract Cortical bone is semi-brittle and anisotropic, that brings a challenge to suppress vibration and avoid undesired fracture in precise cutting process in surgeries. In this paper, a novel analytical model is proposed to represent cortical bone cutting processes.
