Electrochemical micromachining (ECMM) is a non-conventional manufacturing method suitable for the production of microsized components on a wide range of conductive materials. ECMM improves dimensional accuracy and simplifies tool design for machining hard, high strength, heat resistant, and conductive materials into complex shapes. Extremely small interelectrode gaps of the order of few microns...

Silicon carbide (SiC) is one of the advanced engineered ceramics materials designed to operate in extreme environments. One of the main reasons for the choice of this material is due to its excellent electrical, mechanical and optical properties that benefit the semiconductor, MEMS and optoelectronic industry respectively. Manufacture of this material is extremely challenging due to its high ha...

In order to machine the complex free surface, in this paper, NC interpolation of any complex surface is realized used the recursive reconstruction algorithm. The interpolating errors of this algorithm are controllable, and its applicability is relatively wide. Then, these NC codes of the complex human’s free surface are obtained with data exchange of the manufacturing module in the software UG,...

Laser micromachining has the capability to fabricate very small and basic 2.5 D geometric features on a range of materials in the form of laser ablation or irradiation. Short pulsed lasers that can achieve wide range of wavelengths in the form of harmonics of infrared laser beam at 1064 nm wavelength have been a very effective micro-machining tool used for hole drilling, cutting, scribing, trim...

In this Research, the desktop micro forming manufacturing system has been developed. A micro forming system has been achieved in Japan and its developed micro press is limited to single forming process. To coincide with the purpose to be more practical, research and development is necessary about the press which the multi forming process is possible. Micro patterned metal components are used in...

In the current context of miniaturization, micro-machining processes are in full expansion. One of them is micro-milling. Although micro-milling is based on the same principle as macro-milling, the phenomena of micro-cutting are not a simple scaling of macrocutting. A significant difference is the chip formation involving the phenomenon of minimum chip thickness. In micro-milling the depth of c...

In this study, micro fluid channels are machined on fused silica glass via powder blasting, a mechanical etching process, and the machining characteristics of the channels are experimentally evaluated. In the process, material removal is performed by the collision of micro abrasives injected by highly compressed air on to the target surface. This approach can be characterized as an integration ...

Waterjet technology has been extensively used in machining processes since 1970’s, and in the last years it has evolved to a precision machining tool for micro workpieces, namely micro abrasive-waterjet blasting (μAWJB); nevertheless, as a finishing process to remove micro-burrs it has not been yet developed. Our experimental studies on low-pressure μAWJB showed that conventional nozzles which ...

In the field of Abrasive Water Jet (AWJ) machining, the current focus is on the fabrication of complex threedimensional features. The current work is aimed at using this strategy to manufacture micro-tools for machining arrays of square holes using Electric Discharge Machining (EDM). Based on selected parameters of AWJ process(step over, traverse speed, path strategy),micro tools were fabricate...
