Serrated Chip Morphology and Comparison With Finite Element Simulations

Manufacturing Engineering and Materials Handling Engineering, 2004
The complexity of chip formation in machining processes stems from the confluence of several physical phenomena — mechanical, thermal, and chemical — occurring at very high strain rate. The prediction of chip morphology depends on a fundamental understanding of these phenomena and is of industrial importance for cutting force prediction and surface ...

Evaluation of chip morphology during machining of ECAE titanium

2016 International Symposium on Flexible Automation (ISFA), 2016
Titanium (Ti) and its alloys are currently used extensively in medical and dental applications due to their superior mechanical and physical properties compared to coarse-grained (CG) Ti. However, the presence of alloying elements such as aluminum and vanadium has raised concerns about Ti alloy biocompatibility.

A chip design for binary and binary morphological operations

Proceedings 1999 International Conference on Information Intelligence and Systems (Cat. No.PR00446), 2003
A design for a chip to perform binary and binary morphological operations is provided. The chip is intended to be a part of a pipeline machine controlled by a general purpose processor. It could process 25512/spl times/512 pixel frames per second in one pixel per clock cycle rate. In real time application an array of this chip could be used, leading to

Micro chip with nanostructured membranes for cell morphology monitoring

2007 7th IEEE Conference on Nanotechnology (IEEE NANO), 2007
We present a novel nanostructured micro cell chip with impedance spectroscopy for monitoring cell morphology change non-invasively, in real time and independent of any fluorescent or radioactive probes. The key strategy is to integrate the nanoporous alumina membrane with silicon based microfluidic devices for the impedance monitoring.

FE Study of the Chips Morphology when Drilling Process

Applied Mechanics and Materials, 2015
The finite element modeling allows manufacturers to reduce the cost of machining operations. During a drilling operation, the chips morphology their sizes and thicknesses have a great effect on the process, whatever the material to be machined. One approach to a 3D simulation of a drilling process with the finite element program Abaqus/Explicit is ...

A morphological filter chip using a modified decoding function

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2000
This paper proposes a new very large scale integration architecture for cost-effective morphological filters and presents its design and chip implementation. The proposed architecture can reduce the hardware cost by using a feedback loop path and a decoder/encoder pair comparator. The feedback loop path can reuse partial results to reduce the number of

Chip Morphology and Forces in End Milling of Elastomers

Journal of Manufacturing Science and Engineering, 2004
This paper describes chip morphology and forces in end milling of elastomers. A classification system that identifies elastomer chips based on their size and morphology is described. Optical pictures and Scanning Electron Microscopy (SEM) micrographs were used to examine and classify chips.

Cutting Theory and Chip Morphology

1985
Machining is a mechanical process where excess material from a workpiece can be removed by cutting action to produce a part of specified geometrical shape and surface finish. Machining can be performed on virtually all solid materials even though the term commonly applies to the cutting of metals and alloys, less frequently to plastics and wood, and ...
