Improving the quality of surface molds after electrical discharge machining is still being considered by many researchers. Powder-mixed dielectric in showed that it one processing methods with high efficiency. This article reports on results mold steels powder-mixed using titanium powder fine machining. The process parameters such as electrode material, workpiece polarity, pulse on-time, off-time, current, and concentration were research. These materials are most commonly used die-sinking...
This paper aims to analysis the effect of coolant parameters on surface roughness in internal cylindrical grinding annealed 9CrSi steel. The concentration and flow rate are investigated thirteen experiments by central composite design response method. each parameter their interaction analyzed regression model. From that model, optimal determined obtain minimum roughness. measured matches with predicted from proposed is proven it can be further applied for optimizing other machining processes.
Abstract This study aims to optimize the dressing parameters of grinding wheel for 9CrSi tool steel minimize roughness average and flatness tolerance using Taguchi method Grey Relational Analysis (GRA). These objectives are minimized by optimizing four four-level two two-level in sixteen experiments based on an orthogonal array L 16 (4 4 ×2 2 ). GRA combined solve multi-objective optimization problem determine optimal parameter level combination. Results show that, obtain minimal coarse...
In electro-discharge machining (EDM) with mixing powder, it is called powder mixed (PMEDM), then performances- i.e. material removal rate(MRR) and tool wear rate (TWR) has great significance in evaluating the effectiveness accuracy of method. Therefore, this study, response surface methodology (RSM) was utilized for estimating functions process variables {comprising peak current (Ip), pulse on time (Ton), concentration (Cp)} performances processing SKD61 steel during EDM tungsten compound...
Enhanced productivity and workpiece surface quality after electrical discharge machining (EDM) is a concern of many researchers. In this study, the effect powder concentrations on material removal rate (MRR), roughness (SR) topography in mixed EDM (PMEDM) was investigated. The experimental studies were conducted keeping various parameters like current, voltage pulse time constant while using varying titanium powder. Experimental research methods employed to study performance characteristics...

Vietnam is on its way to becoming a more developed country and integrated into the global community.One of most important key factors for development science technology.Scientific publications bring up-to-date information scientists, researchers, society.The quality Vietnam's scientific journals should be increased international level.Also, number high articles published in from limited compared researchers Vietnam.There still no Vietnamese journal indexed Web Science up January 2015; while,...
The vacuum pump usually used traditional curves such as the circular, cycloidal and their combinations to construct tooth profile. However, increase efficiency design flexibility for pump, a novel rotor profile Roots of pumps is proposed. Which named “CEIEC” orderly composed five significant segments, circular arc tip, an epicycloid curve with variable extension, involute, enveloped conjugated root. A numerical example presented evaluate performance indices proposed including hermeticity...
