Influence of Cutting Compound on Critical Cut Depth of Glass BK7

Key Engineering Materials, 2013
In diamond cutting of optical glasses, the magnitude of critical depth of cut for brittle-ductile transition is an important factor affecting the machinability of the work material in terms of production rate and surface quality. In this work, scratching tests with increasing depths of cut were conducted on glass BK7 to evaluate the influence of the ...

Cutting planes and constant depth Frege proofs

[1992] Proceedings of the Seventh Annual IEEE Symposium on Logic in Computer Science, 2003
The cutting planes refutation system for propositional logic is an extension of resolution and is based on showing the nonexistence of solutions for families of integer linear inequalities. The author defines a modified system of cutting planes with limited extension and shows that this system can polynomially simulate constant-depth Frege proof ...

Lubricant Applying Effect Mechanism in Inconel 718 Cutting - Effects of Cutting Speed and Depth of Cut -

Advanced Materials Research, 2011
Applying materials on the precut surface of ductile metal cuttings can greatly improve their machinability, due to the reduction in friction between the lamella of the chip. We refer to this effect as the lubricant applying effect. This paper investigates the influences of the lubricant applying effect on the cutting of the super alloy Inconel 718. The

Effect of Cutting Tool Properties and Depth of Cut in Rock Cutting: An Experimental Study

Rock Mechanics and Rock Engineering, 2018
The current paper is designed to investigate the effect of worn (blunt) polycrystalline diamond compact cutter properties on both the contact stress ( $$\sigma$$ ) and friction coefficient (μ) mobilized at ...

Depth image in-loop filter via graph cut

2016 IEEE International Conference on Image Processing (ICIP), 2016
With the ability of representing 3D scene geometry, depth maps are used to synthesize virtual views in free view video (FVV) or 3DTV. However, compression artefact of the depth images always lead to seriously geometry distortions in synthesized view, which severely affects the visual perception of 3D display.

Stereo estimation of depth along virtual cut planes

2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011
Stereo vision is broadly employed in robotics and intelligent vehicles for recovering the 3D structure of the environment. The scene depth is typically estimated by triangulation after associating pixels between views using a dense stereo matching approach. In the last few years, the image resolution has steadily increased due to the advances in camera

In-process control of cutting depth during turning

SICE Annual Conference 2007, 2007
During the turning process of a ring, the clamping force of the chuck causes circumferential deviations in the ring wall thickness and diameter. In order to minimise the wall thickness deviations, an experimental set-up for an in-process control of the cutting depth during turning is being developed. The set-up comprises a fast tool unit, an ultrasonic

Depth of cut models for multipass abrasive waterjet cutting of alumina ceramics

International Journal of Abrasive Technology, 2010
Predictive models for the depth of cut in multipass abrasive waterjet (AWJ) cutting of alumina ceramics are presented. Cutting operations both with and without nozzle oscillation are considered. The modelling process starts with the single pass cutting using a dimensional analysis technique and the particle erosion theories applied to alumina ceramics,
