On-line monitoring of depth of cut in AWJ cutting

International Journal of Machine Tools and Manufacture, 2004
Monitoring of the abrasive waterjet (AWJ) cutting process has become increasingly important. The present paper proposes a model for on-line depth of cut monitoring based on the acoustic emission (AE) response to the variation in AWJ depth of cut, instead of the expensive and impractical vertical cutting force monitoring.

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 ...

NanoTags for Improved Cuttings Depth Correlation

Petrophysics – The SPWLA Journal of Formation Evaluation and Reservoir Description, 2021
During a drilling operation, rock cuttings are often sampled off a shale shaker for lithology and petrophysical characterization. These analyses play an important role in describing the subsurface, and it is important that the depth origin of the cuttings be accurately determined.

Reserch on Cutting Depth Effect in Cutting Process

Applied Mechanics and Materials, 2011
In the cutting procedure, the cutting depth influences cutting forces, chip breaking, chip shaping, and the distribution status of residual stress. The two-dimension heat-mechanic coupling orthogonal cutting model is established with the FEM analysis software by use of the Lagrange quality point coordinate system description method in this paper.

The Depth of Cut in Drilling Mode of Rock Cutting

Applied Mechanics and Materials, 2017
Drilling and lateral cutting are two cutting modes used by roadheaders in rock cutting. Accurate estimation of the depth of cut (DOC) of the cutterhead of a roadheader is critical for improving the performance and reliabilityofthe roadheader. Some models have been developed for calculating the DOC of a cutterhead in lateral cutting mode.

Cut-Elimination with Depths

2020
In this chapter we first introduce a standard cut-elimination procedure for the first-order logic and the \(\omega \)-logic, by which we see that the tree-height of the resulting cut-free proofs is bounded by a tower of exponential functions. Such a control of the tree-heights in cut-elimination is one of the most important results in ordinal analysis.

Intermittent metal cutting at small cutting depths—2. Cutting forces

International Journal of Machine Tools and Manufacture, 1988
Abstract Cutting forces in intermittent metal cutting at small cutting depths were investigated by single edge experiments. Single cutting strokes were performed in a modified Charpy pendulum tester which offers cutting and thrust force measurement and accurate selection of cutting speed and feed in ranges typical for many intermittent high speed ...
