The already initiated studies are based on size and forms of abrasive grains, but few studies have addressed the influence on the concentration of abrasive grains. This research has been done to remove some of the mysteries associated in the media "abrasives" or "chips" used in vibratory and barrel finishing, this process included within the functions and characte...

Magnetic abrasive finishing (MAF) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. In this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of Al<...

The effect of cutting parameters and tool parameters on cutting forces and tool wear were investigated in high density fiberboard (HDF) peripheral up-milling using toughened ceramic cutting tools. The results showed that whether at low speed cutting or high speed cutting, the tangential forces Ft and normal forces Fr increased slowly with the increase of cutting length. The tangential forces Ft...

Additive manufacturing by laser-based powder bed fusion of metals (PBF-LB/M) enables the production complex shaped components. High-carbon tool steels tend to cracking during PBF-LB/M due internal stresses caused rapid solidification. Expensive atomization and long lead times for generate high costs in this processing route. In situ alloying blends from conventionally available powders a more f...

This paper presents a review on the problems encountered in machining titanium and application of USM in machining titanium and its alloys. Experiments have been conducted to assess the effect of three factors-tool material, grit size of the abrasive slurry and power rating of ultrasonic machine on machining characteristics of titanium (ASTM Grade I) using full factorial approach for design and...

In automation flexible manufacturing systems, tool wear detection during the cutting process is one of the most important considerations. This study presents an intelligent system for online tool condition monitoring in drilling process .In this paper, analytical and empirical models have been used to predict the thrust and cutting forces on the lip and chisel edges of a new drill. Also an empi...

Abrasive wear is defined wear due to hard particles or hard protuberances forced againts and moving along a solid surface. This defination encompasses several different mechanisms by which material removal occoures. The five types of wear are abrasive, adhesive, erosion, fatigue and fretting. The abrasive wear of polymeric materials is the interest and the subject of quite number of literature....

This study focuses on obtaining regression models for material removal rate and tool wear in rough honing processes. For this purpose, experimental tests were carried out according to a central composite design of experiments. Five different parameters varied: grain size or particle abrasive, density abrasive concentration, pressure the stones against cylinder internal surface, tangential speed...

An experimental investigation into material transfer and wear has been performed for the case of a ferrite probe sliding at high speeds (between 25 cm/set and 1250 cm/set) and low loads (10 gm) on a steel disk, a nickel plated disk, and a polymercoated disk, the latter containing finely dispersed abrasive particles. Autoradiographic methods together with microdensitometer analysis have been app...

Polishing abrasives that have been bound in a solid matrix can offer several potential advantages over loose-abrasive processes with pitch or polyurethane laps for finishing of optics. These advantages include polishing efficiency, temperature stability, cost of consumables, and compatibility with computer numerically controlled generating machines. Unfortunately, little has been published on b...
