Effect of Interparticle Interaction on Particle Deposition in a Crossflow Microfilter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies show that interparticle interaction can affect particle trajectories and particle deposition causing fouling in the microfilters used for metal working fluids (MWFs). Interparticle interaction depends on ...
Effect of Dielectric Conductivity on Micro-Electrical Discharge Machining Plasma Characteristics Using Optical Emission Spectroscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electrical conductivity of the dielectric liquid has been shown to play main role in discharge initiation and electrical breakdown as revealed by several modeling and experimental studies on electrical discharges in liquids. ...
Microscale Drilling of Bulk Metallic Glass
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The microscale drilling performance of a Zrbased bulk metallic glass (BMG) is investigated in this paper. Crystallization, drill temperature, axial force, spindle load (SL), acoustic emissions (AE), chip morphology, hole ...
Model Based Prediction of Plasma Resistance, and Discharge Voltage and Current Waveforms in Micro Electrodischarge Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In electrodischarge machining (EDM), the thermal energy causing material removal at the electrodes is given by the electrical energy supplied to the discharge. This electrical energy, also known as the discharge energy, ...
Effect of Dielectric Electrical Conductivity on the Characteristics of Micro Electro Discharge Machining Plasma and Material Removal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In micro electrodischarge machining (microEDM), it is believed that electrical conductivity of the dielectric modified by additives plays an important role in discharge initiation and electrical breakdown, thereby affecting ...
Study of Film Formation on Grooved Tools in an Atomization-Based Cutting Fluid Delivery System for Titanium Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to study the effect of cutting tool surface geometry and the atomization-based cutting fluid (ACF) spray parameters on the characteristics of the thin film formed in an ACF delivery system. A ...
A Study on Native Oil Components Depletion of Industrial Metalworking Fluid During Microfiltration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The depletion of native oil components from semisynthetic metalworking fluids (MWFs) during microfiltration is caused in part by the deposition of the MWF components on the pore walls, a mechanism that also results in the ...
On Cutting Temperature Measurement During Titanium Machining With an Atomization Based Cutting Fluid Spray System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The poor thermal conductivity and low elongationtobreak ratio of titanium lead to the development of extreme temperatures (in excess of 550 آ°C) localized in the tool–chip interface during machining of its alloys. At ...
Modeling of Melt Pool Formation and Material Removal in Micro Electrodischarge Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a microelectrodischarge machining (EDM) meltpool model to predict workpiece (anode) material removal from a single discharge microEDM process. To model the meltpool, heat transfer and fluid flow equations ...
Finite Element Based Study of the Mechanics of Microgroove Cutting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an earlier paper, a highspeed microgroove cutting process that makes use of a flexible singlepoint cutting tool was presented. In this paper, 3D finite element modeling of this cutting process is used to better understand ...
