INTRODUCTION The North American manufacturing industry has seen a growing demand for precision machined components in recent years. Biomedical devices, micro-optical moulds, and automotive parts are examples of precision manufactured components. Traditional milling practices have reached the limit of the machines’ accuracy and cannot achieve high tolerances now demanded in the micro-machining f...

A machining operation is basically termed a material removal process, where material is removed in the form of chips. In a machining operation, the output parameter is achieved by controlling various input parameters. This paper discusses the effects of various input parameters in abrasive Jet machining (AJM) on the output parameter(Metal Removal Rate [MRR).This paper presents an extensive revi...

This research proposes an optimized magnetic abrasive machining process that uses an ultra-high-speed system to perform precision machining on a workpiece. The system can process several microns of material, either for machining surface roughness or for machining a workpiece for a precise micro-diameter. The stainless steel workpieces have been machined using an ultra-high-speed magnetic abrasi...

One of the major difficulties in extracting machining features is the lack of a systematic methodology to generate alternative ways of manufacturing a machined part. Most of the early research in feature extraction and process planning has not considered this aspect, and has focused on the generation of a single interpretation. In this paper, we propose a featurebased approach to generating alt...

The e-glass fibre epoxy composite is a nonconductive ceramic material hence it is difficult to machine by any well known non-conventional machining methods like electrical discharge machining, wire electrical discharge machining etc. This material can be machined with conventional machining but compromise with accuracy, surface texture even not possible to micro slicing etc. Keeping in view, a ...

The purpose of cutting fluid in a machining operation is to cool the workpiece, reduce friction, and wash away the chips. The cutting fluid contributes significantly toward machining cost and also possesses environmental threats. In the past, there have been some attempts to minimize the amount of cutting fluid in machining. This chapter reviews some prominent ways to minimize the application o...

This paper introduces machining of optics, presenting some of the history of machining progress, critical machining variables, material and geometrical capabilities, and some new results on optical evaluation of machined surfaces. A most significant development is electroplating of materials that are otherwise not presently machinable. For example, molybdenum has been electroplated with silver ...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...

Today's forging die manufacturing process must be adapted to several evolutions in machining process generation: CAD/CAM models, CAM software solutions and High Speed Machining (HSM). In this context, the adequacy between die shape and HSM process is in the core of machining preparation and process planning approaches. This paper deals with an original approach of machining preparation integrat...

Condition monitoring and diagnosis systems capable of identifying machining system defects and tiieir location are essential for unmanned machining Unattended (or minimally manned) machining would result in increased capital equipment utilization, thus substantially reducing the manufacturing costs. A review of tool monitoring systems and techniques and their components and the Multiple Princip...
