Abstract This paper presents the machining process of the complex copper electrodes. Machining of the complex shapes in copper is difficult because this material is soft and sticky. This research presents the main steps for processing those copper electrodes at a high dimensional accuracy and a good surface quality. Special tooling solutions are required for this machining process and optimal process parameters have been found for the accurate CNC equipment, using smart CAD/CAM software.

The design, modeling and simulation are one of the key technologies of CAD/CAM software system. The mathematical model of the CAD/CAM system for machining spatial surface was given firstly. After the design idea of the CAD/CAM system was describe in detail, the workflow of the CAD/CAM software system was illustrated, and then data exchange mechanism was determined and detailed steps were given simultaneously. Under MFC framework, the CAD/CAM software system was finished using OpenGL, and the configuration and machining process simulation were carried out. All these works provide an effective approach to raising the productivity and precision of machining spatial curve surface part by WEDM-HS.

The future development of the manufacturing is using VR technology to make the machining simulation before the actual machining process made. The machining simulation of Ultra High-speed Grinding Machine Tool is researched in this paper. Firstly, using UG/NX software and VRML, the geometric modeling of machine tool is modeled. Secondly, through using Java and Javascript language, the operation and display of machining process of ultra high-speed grinding are realized. The main technologies include NC codes compiling, collision detection and material removal. Thirdly, the example of machining simulation using virtual ultra high-speed grinding machine tool can be obtained in the paper. Compared to other CNC machining simulation methods, the method in the paper has reality display, rich features, a good man-machine interaction, etc., and it does not rely on expensive CAD/CAM software. The system files generated by the machining simulation have the small size and can be transferred on the network easily.

Lamp System

Even though the machining process has been integrated to the Multi-Axis Laser Aided Manufacturing Process (LAMP) System in order to get good surface finish functional parts [1], the quality of parts produced by the LAMP system is still very much dependent upon the choice of deposition paths. [2] Raster motion paths are replaced by offset spiral-like paths, which are discussed in this paper. Most commercial CAD/CAM packages are feature-based, and their use requires the effort and expertise of the user. The shape has to be decomposed into manufacturing features before the software packages can generate the paths. [3] Path planning has long been studied as discussed in this paper. There are still some problems associated with the previous algorithms and also assumptions are usually made. [6, 7, 27] An algorithm for directly generating offset edges, which can be developed to be the deposition paths, is presented in this paper. The skeleton of a layer or a slice of a 3-D CAD drawing is first generated. Based on that skeleton, the offset edges are incrementally constructed. This paper focuses on the characteristics of skeleton and offset edges as well as the construction algorithm for those edges. Simulations are used to verify this method.

Disappearing mould casting is a new accurately processes with nearly free margin and precision forming, in which is no modulus, no parting, no sand core, so the casting without splash, burr and taper angle. It can improve the dimensional accuracy of the core portfolio for complex surface of the key compose of the disappearing mould. It has completed the design and manufacturing of these by the three-dimensional CAD/CAM technology, and obtains a series of effective methods and experience for the development of the products. The researched results have important directive to production practices for the design and machining process for the expendable pattern casting.

Analysis of a formed metal sheet shows the data of the incremental forming process. Variation in sheet deformation results from the process and shows how forming occurred. Another important result is the surface roughness of the sheet, which reports the parameters of the process, machine and tool used. Incremental forming of the titanium CP-Ti grade 2 sheet was performed in the SPIF modality – forming without a point of support, in order to look at the thickness deformations. SPIF incremental forming is characterized as forming that does not use points of support, and therefore simple tooling is used in the process. The following resources were used to perform the practical tests: CAD/CAM software, CNC machining center, incremental die, incremental forming tool and a sheet press device. The results obtained were the finish of the formed surface, measured by the roughness parameter RZ, and the measurement of the true strains ( ) and thickness (s1). Practical tests showed that the limit wall angle ( ), for the CP Ti grade 2 sheet, 0.5 mm thick, is 47º.

This paper highlights the detailed procedure for preparation of biocompatible sensors and transducers by CAD-CAM assisted investment casting (IC). Along with the properties such as biocompatibility and bioactivity, the presented materials possess good surface finish (required for aesthetic sense), acceptable dimensional accuracy (required for assembly purposes) and good surface hardness (required while chewing). In this paper efforts were made for improving surface hardness, finish, and dimensional accuracy of biocompatible materials by controlling composition/proportion of Ni and Cr in IC process. In this case study stir casting (SC) assisted Ni and Cr based metal matrix composites (MMC) has been prepared and composite prepared were poured in the investment mould. The result of study reveals that different material composition influenced the microstructure and the hardness of the MMC prepared. Further with change in weight percentage of Ni and Cr, different microstructures with particle clustering was observed. The employment of nickel and chromium composites for the fabrication of novel sensors and transducers is discussed.
