Cutting Experiments in Cutting Speeds of up to 200 m/s with a High-Speed Impact Cutting Tester
Key Engineering Materials, 2012High-speed orthogonal cutting experiments with cutting speeds of up to 200 m/s with a high-speed impact cutting tester of air-gun type are attempted. In this tester, a light projectile with a small built-in cutting tool is loaded into a tube, being accelerated by a compressed gas.

Effects of Friction and Cutting Speed on Cutting Force
Manufacturing Engineering, 2001Abstract Observations are made regarding the influence of cutting speed and friction on cutting force by way of finite element modeling. Simulations are validated by comparison of cutting forces and chip morphologies for the A16061-T6. Analysis of cutting forces over a wide range of cutting conditions suggests an important role of the ...

Honing with increase in the cutting speed
Russian Engineering Research, 2008The honing methods with constant tool speed currently employed do not fully utilize the potential of each abrasive grain and the tool as a whole in producing high surface quality [1, 2, etc.]. Variation in speed of the honing head is proposed to permit more complete utilization of the tool’s potential, reduce tool wear, and improve the quality of the ...

High-speed cutting of foods: Cutting behavior and initial cutting forces
Journal of Food Engineering, 2018Abstract The viscoelastic properties of foods determine deformation, fracture and friction during industrial cutting applications and substantially affect the cutting behavior, especially at high cutting velocity. Using a custom-built high-speed test station the cutting behavior of representative foods (either based on a protein network, plant ...

Speed effects in cutting and ploughing
Géotechnique, 1999A significant speed effect occurs when blades and ploughs cut saturated soil. The cutting force increases dramatically with cutting speed, sometimes by a factor of five or more. In some soils, the effect occurs at very low speeds. It has significant practical implications, and has caused difficulties in several projects. The effect is explained by the

A study of oblique cutting for different low cutting speeds
Journal of Materials Processing Technology, 2001Abstract In this paper, the finite deformation theory and an updated Lagrangian formulation (ULF) were used to describe the oblique cutting process. Either the tool geometrical location condition or the strain energy density constant was combined with the twin node processing method to be adopted as the chip separation criterion.

The Effects of Cutting Speed on Continuous Miner Cutting Performance
Advanced Materials Research, 2010In order to study the effects of cutting speed on a continuous miner cutting performance, set up the equations of Cantilever’s swing speed, draw graph of chips in different swing speed and rotate speed, analysis the effects of them on continuous miner cutting performance. In order to reduce the fluctuation of cutting speed and get large lump coal rate ,

In certain contexts, high speed cutting is only defined as machining at high cutting speeds (spindle speeds) and/or at high feed rates in order to achieve short machining- or lead times. However, for a reasonable classification, one has to consider the material to be machined (soft- or hard machining), the cutting materials and the metal removal rate.

Intelligent Speed Planning Based on Cutting Forces
2018 IEEE International Conference on Information and Automation (ICIA), 2018The goal of this project is to use a new method—hinging hyperplane approximation to solve the problem of discontinuities between track segments and track trajectories. Based on this, a new speed planning method is proposed to solve the problem of uniaxial jumps.
