Volume 4, Issue 3, May – June 2015 Page 106 ABESTRACT In recent years, various researchers have come up with different ways and means to integrate CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing). The selection of machining parameters is an important process planning function for manufacturing processes.Typically, machining parameter selection is done manually. The user still ...

ABSTRACT The objective of this investigation is to obtain an optimal setting of process parameters in turning for maximizing the material removal rate of the manufactured component. The material removal rate has been investigated in this analysis while machining practically used components. As per Taguchi’s “Design of Experiments”, the number of experiments to be conducted in this analysis is c...

A new dynamical modeling of Active Magnetic Bearing Spindle (AMBS) to identify machining stability of High Speed Milling (HSM) is presented. This original modeling includes all the minimum required parameters for stability analysis of AMBS machining. The stability diagram generated with this new model is compared to classical stability lobes theory. Thus, behavior’s specificities are highlighte...

WEDM process is used extensively where the conventional machining process shows their limitations. Wire Electrical Discharge Machining is used to manufacture geometrically intricate shapes with higher accuracy and better surface finish. In the present study, the performance parameters i.e. cutting speed and surface roughness were investigated. The experiments were conducted under the constant c...

Abrasive waterjet machining (AWJM) is one of the modern machining process for difficult to cut materials. It is an environment friendly and relatively inexpensive process with reasonably high material removal rate. In all the machining processes the quality of the work piece is depends on various design parameters. The process parameters which mainly affect the quality of cutting in AWJM are Hy...

Influence of machining parameters, viz., spindle speed, depth of cut and feed rate, on the quality of surface produced in CNC end milling is investigated. In the present study, experiments are conducted for three different workpiece materials to see the effect of workpiece material variation in this respect. Five roughness parameters, viz., centre line average roughness, root mean square roughn...

Purpose: In this paper, the effects of various process parameters of WEDM like pulse on time (TON), pulse off time (TOFF), gap voltage (SV), peak current (IP), wire feed (WF) and wire tension (WT) have been investigated to reveal their impact on material removal rate of hot die steel (H-11) using one variable at a time approach. The optimal set of process parameters has also been predicted to m...

Today one of the top priorities in the machining industry is to increase or retain the profit margin through cost reduction. In addition, consumers are becoming increasingly aware of the impact that the life cycle of products has on the environment, at the time of their choice. So companies are required to research and develop sustainable processes or adapt existing ones. This research has been...

The reliability of machining accuracy is of great significance to performance evaluation and optimization design of the machine tools. Different geometric errors have various influences on the machining accuracy of the machine tools. The main emphasis of this paper is to propose a generalized method to distribute geometric accuracy of component for improving machining accuracy reliability under...

Background: Electrical Discharge Machining (EDM) is a well-established non-conventional machining process for the machining of electrically conductive and difficult-to-machine materials. But its applications are limited because of the slow machining rate and poor surface finish. Powder mixed EDM (PMEDM) is unitary of the recent progresses in the EDM process in which powder particles mixed in th...
