The paper proposes multi-operation blank localization to fit final product geometries into near net shape blanks. Groups of machining features are located subject tolerance intervals on their relative positions and a lower bound the allowance which accommodates for uncertainties measurement machining. error, i.e., deviation resulting dimensions from center is minimized. problem formulated as co...

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...

Conductive ceramics like cobalt bonded tungsten carbide which is categorized as with high mechanical and physical properties are usually known to create major challenges during conventional and non-conventional machining. Electrical discharge machining (EDM) which is very prominent amongst the non-conventional machining methods is expected to be used quite extensively in machining it due to the...

Surface roughness is considered as one of the most specified customer requirements in machining processes. For efficient use of machine tools, selection of machining process and determination of optimal cutting parameters (speed, feed and depth of cut) are required. Therefore, it is necessary to find a suitable way to select and to find optimal machining process and cutting parameters for a spe...

Abrasive flow machining also known as abrasive flow deburring or extrude honing, is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a work piece. This fluid is typically very viscous, having the consistency of putty, or dough. In this paper, the main purpose of the process is to investigate the surface finishing of die steel with the use of abrasiv...
