This chapter first describes the robotic CAM system proposed from the viewpoint of robotic servo controller for an industrial robot RV1A. Then, a reverse post-processor is proposed for the robotic CAM system to online generate the original CL data from the NC data post-processed for a five-axis NC machine tool with a tilting head. Next, an application of the industrial robot with incorporated t...

A study comparing the electrophoretic separation performance attainable from microchips molded by masters fabricated using conventional CNC machining techniques with commercial microchips, wire imprinted microchips, and microchips from LIGA molding devices is presented. An electrophoresis-based detection system using fluorescence microscopy was used to determine the analytical utility of these ...

Silicon micromachined terahertz passive components such as silicon washers, waveguide blocks for W-band (75-110 GHz) power amplifiers, and waveguides for 325-500 GHz band have been designed, microfabricated, and characterized. Based on these results, an integrated 600 GHz silicon micromachined RadiometerOn-a-Chip (ROC) has been demonstrated for the first time. It reduced in mass by an order of ...

There is a huge demand in the production of microstructures by a non-traditional method which is known as Micro-EDM. Micro-EDM process is based on the thermoelectric energy between the workpiece and an electrode. Micro-EDM is a newly developed method to produce micro-parts which in the range of 50 μm -100 μm. Micro-EDM is an efficient machining process for the fabrication of a micro-metal hole ...

The most emerging needs of the modern metal cutting operation are to increase the material removal rate with better surface finish and high machining accuracy. These objectives can be achieved by reducing cutting temperature in the cutting zone. In metal cutting process, high cutting temperature and its detrimental effects are generally reduced by proper selection of process parameters, proper ...

An overview of issues concerning current methods of rapid prototyping (RP) processes is presented. This paper establishes a basis for categorizing the models developed by both commercial RP systems and conventional means, in particular, CNC machining. Model accuracy in both representation and testing capability is described based on a set of three defining levels, Form, Fit, and Function. This ...

Advanced ceramic materials are gradually becoming very important for their superior properties such as high hardness, wear resistance, chemical resistance, and high strength to weight ratio. But machining of advanced ceramic like Al2O3-ceramics is very difficult by any well known and common machining processes. Normally, cleavages and triangular fractures generate when machining of these materi...

Non-oriented electrical steel (NOES) laminations are commonly used to manufacture the rotor and stator core of electric machines. To achieve high machine efficiencies, it is desirable for these NOES be able a saturation magnetisation whilst incurring minimal losses. It known that inappropriate machining could cause significant deterioration in their magnetic properties. However, mechanisms by w...

The selection of optimum process parameters is crucial for advanced machining processes, as these processes incur high initial investment, tooling cost, and operating and maintenance costs. In this paper, a review of machining process parameters for different materials is done in ultrasonic machining (USM). Machining of Different materials like ceramics, Glass Porcelain, Titanium, is done by di...
