The quality of a machined surface is becoming more and more important to justify the increasing demands of sophisticated component performance, longevity, and reliability. Usually, any machining operation leaves its own characteristic evidence on the machined surface in the form of finely spaced micro irregularities (surface roughness) left by the associated indeterministic characteristics of t...

Titanium alloys have been widely used in the aerospace, biomedical and automotive industries because of their good strength-to-weight ratio and superior corrosion resistance. However, it is very difficult to machine them due to their poor machinability. When machining titanium alloys with conventional tools, the tool wear rate progresses rapidly, and it is generally difficult to achieve a cutti...

Nowadays, the demand for high product quality focuses extensive attention to the quality of machined surface. The (CNC) milling machine facilities provides a wide variety of parameters set-up, making the machining process on the glass excellent in manufacturing complicated special products compared to other machining processes. However, the application of grinding process on the CNC milling mac...

The goal of this project is to build and deploy the model based control strategies for machining processes and systems of these processes. With the advances in sensing and real-time control technology coupled with Open Architecture Control (OAC) CNC systems, there is a great potential of deploying such control algorithms for various aspects of machining process. Some of these areas include work...

Abrasive machining is one of the most non-conventional processes for finishing. It is widely used in industry to machine the materials like mild steel, aluminum, copper, titanium, glass, hard rock material, graphite, composite material, ceramics etc.Like in abrasive jet machining. This technique uses jet which contains abrasive material. Now a day water-magnetic abrasive machining is one of the...

An aspherical supermirror is one of the most useful neutron-focusing optics. We aim to develop multiple aspherical supermirror devices using high-precision figured aspherical focusing supermirrors to focus neutron beams with high intensities, because multiple mirrors collect a very large beam divergence. Thin mirrors with a millimeter thickness are required to minimize the absorption loss of in...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

High speed machining of hardened steels for manufacturing dies and molds offers various advantages, but the productivity often limited by mainly tool life. This study investigates the influence of edge preparation in cubic boron nitrite (CBN) cutting tools on process parameters and tool performance by utilizing practical finite element (FE) simulations and high speed orthogonal cutting tests. T...

The main aim of this work is to investigate the actuator driving force variations of a parallel kinematic machine (PKM) for different cutting paths. To meet this aim, a TRR-XY Ž ve-degrees-of-freedom (5DOF) PKM was selected and built for this research, and a dynamic analysis model of the PKM was developed. Here, ‘T’ stands for translational DOF and ‘R’ stands for rotational DOF of the platform....

In this study, three different vegetable-based cutting fluids developed from raw and refined sunflower oil and two commercial types (vegetable and mineral based cutting oils), were carried out to determine for thrust force and surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool. The uses of vegetable cutting oils was investigated in reducing thrust force and ...
