A computed tomographic measurement based in sensing the introduced phase changes of a transparent sample is implemented. The interferometry system is composed by a Polarizing Michelson interferometer coupled to a pixelated camera in order to acquire the necessary phase shifted interferograms instantaneously. By obtaining measurements at different angles of rotation, added with computed tomographic algorithms, inner information of the sample is obtained. Characteristics and limitations of the implemented system will be explained and experimental results showing the inner distribution phase change of a high temperature torch will be presented.

In this work we combine optical flow and stereo vision algorithms, for obtaining a three dimensional object tracking system capable two follow changes varying in time. The optical flow algorithms allows the study of displacements varying in time and by using a stereo vision system we can retrieve the coordinates of the objects observed in the three axes (x, y, z) and therefore the reconstruction of such objects. A stereo vision system was implemented in Matlab using two identical webcams placed in parallel geometry. The ultimate goal of this project is to have a portable and affordable system that takes into account the disadvantages intrinsic of the implementation such as limited resolution and distortion presented on it for being webcams. Experimental results and system limitation analysis will be presented.

Inclusions in a bearing steel can cause rolling contact fatigue failure because it leads stress consentration and crack generation. In this study, we focusd on 3D shapes of inclusions and their influences on the fatigue failure. We developed a novel framework of analyzing a 3D geometric shapes of internal micro-structure of steel materials. Our analysis indicated that concavity of inclusion shapes caused crack initiation.

A curved-hole machining method by EDM using an electrode consisting of a metal ball suspended with a lead copper foil from the spindle head of an electro-discharge machine has been proposed and the machining characteristics has been discussed . This report discusses the effects of the diameter and mass of the metal ball on electrical discharge machining. The use of a 5.5-mm-diameter ball electrode may provide stable machining performance under a wide range of electric conditions. On the other hand, with decreased ball diameter and mass, the stably machinable conditions are limited to lower discharge current and higher servo voltage. A smaller diameter hole can be machined by using a 3.0-mm-diameter ball under the optimum conditions. Additionally, a curved hole is successfully machined in this study by varying the tilt angles of the workpiece.

The modeling and simulation of Pulsed Wire Electrochemical Machining (PWECM) is considered in this paper. The electrode kinetics was modeled with Butler-Volmer equation to simulate the transient current response behavior of the PWECM system. The evolution of the workpiece surface was then calculated using the machining speed which derived from the local current density. Examples of PWECM and WECM with DC voltage showed that the PWECM results in much smaller machining rate, and improved machining accuracy could be achieved with PWECM.

Micro-rods have to be prepared for micro electrical discharge machining (EDM) and micro electrochemical machining (ECM) to be used as tool electrodes. In most cases, they are fabricated by EDM. On the other hand, the electrostatic induction feeding method developed by the authors was used to machine micro holes by ECM in the past. Hence, the authors tried to fabricate micro rods using this ECM method. The influence of the voltage amplitude on machining stainless steel rod was investigated. The current flowing through the side gap affected the machined shape of the rod. In some cases, the machining failed unexpectedly due to pitting corrosion because stainless steel was machined with sodium chloride electrolyte.

Machining method by combining EDM and grinding with a rotary PCD disc wheel can be precisely machined to cemented carbide using only a single tool. In this study, when a single PCD segment is mounted to the rotating axis on the EDM machine, we proposed to use this tool as a discharge electrode and a finish grinding wheel. From the processing experimental results of cemented carbide by using this tool, it is clarified that electrodes is non consumable in the case of electrical discharge machining, and furthermore the finish surfaces on the cemented carbide after grinding is improved.
