To improve surface accuracy of the work-piece and obtain potentially valuable information, a dynamic milling force prediction model was proposed based on data mining. In view current obtained through finite element simulation analytical calculation, in modeling, built is inevitably different from actual working conditions, calculation slightly cumbersome complex, mining proposed. The establishe...

Pistachio paste is produced from ground roasted kernel. This study focused on the influence of the milling process on colloidal stability, rheological behavior and color of pistachio paste. The colloidal stability of pistachio paste samples increased with a reduction of particle size from 31.4 to 15.10µm. The Herschel-Bulkley model was found to be the best model to describe the flow behavior of...

A strain-type three-component table dynamometer is presented in this paper, which reduces output errors produced by cutting forces imposed on the different milling positions of a workpiece. A sensor structure with eight parallel elastic beams is proposed, and sensitive regions and Wheastone measuring circuits are also designed in consideration of eliminating the influences of the eccentric forc...

The installation of suitable sensors close to the tool tip on milling centres is not possible in industrial environments. It is therefore necessary to design virtual sensors for these machines to perform online fault detection in many industrial tasks. This paper presents a virtual sensor for online fault detection of multitooth tools based on a bayesian classifier. The device that performs thi...

The high demand for carbon composite in many industries results in an increase in the embodied energy footprint of carbon composites. Recycling technologies for carbon composites are being developed to reduce the embodied energy footprint of the material. The purpose of this research is to analyze and estimate the specific energy consumption from mechanical recycling method, specifically a ball...

Highly reflective magnetic powders have been available commercially for latent fingerprint development on dark background surfaces for a few years, however there are needs of a superior darker variety of the magnetic powder which would be ideally suitable for obtaining good contrast on light background surfaces. A novel dark magnetic powder is therefore suggested for the application in latent f...

A New Geometric-and-Physics Model of Milling and An Effective Approach to Medial Axis Transforms of Free-form Pockets for High Performance Machining Qiang Fu, Ph.D. Concordia University, 2010 Mechanical part quality and productivity depend on many parameters in CNC milling processes, such as workpiece material, cutters, tool paths, feed rate, and spindle speed, etc. To pursue high performance m...

Top-down approach has been viewed as an efficient and straightforward method to prepare nanosized zeolites. Yet, the mechanical breaking of zeolite causes amorphization, which usually requires a post-milling recrystallization to obtain fully crystalline nanoparticles. Herein we present a facile methodology to prepare zeolite nanocrystals, where milling and recrystallization can be performed in ...

This paper presents cutting force prediction algorithm for low immersion end-milling, using an efficient dynamic force modeler. The geometric simulation of milling process was performed, using the B-Rep solid modeling techniques. For predicting stability lobes, two methods were used for prediction of stability lobes: the frequency domain technique and the time finite element analysis (TFEA). Th...
