“…Thus far, there have been a large variety of application fields for FEM using these software programs. (6)(7)(8)(9)(10) Concerning the investigation of the machine structure of tool machinery, many studies on the stiffness of machine tools using experimental, analytical, or numerical methods have been carried out. (11)(12)(13) Specifically, Vivekananda et al (14) used ANSYS software to obtain the natural frequency of vibration for ultrasonic turning in the machining process.…”

For tool machinery design, the type of machine structure plays an important role in its final machining precision. In the marketplace, structure types change very quickly because of different application purposes and customers' requirements. Moreover, to develop new and good machine structures, designers usually pay too much time and money in the work of trial and error. For a quick response to market needs, machine makers should find time-saving and money-saving ways to optimally design and verify their products, and accordingly build a reliable database for further modifying and developing new models. In this study, we propose a hybrid design procedure that uses experience and know-how as initial design bases and, together with an optimal Taguchi-based finite element method (FEM), rapidly and efficiently obtains a highly rigid structure. To verify the simulation results, experiments using displacement sensors are also performed. Specifically, in this study, we chose a long-based computer numerical control (CNC) grinding machine as the target because it is a challenge to attain machining precision owing to its weakness feature of a long and narrow structure. With this proposed methodology, machine designers may efficiently and quickly determine the optimal structure of similar types of CNC machine tools.

“…FEM has been successfully applied in many areas, (14)(15)(16)(17) and many FEM programs have been developed, e.g., ANSYS, SOLIDWORKS, NASTRAN, CREO, and INVENTOR. (18,19) SOLIDWORKS has the feature that one may directly use the constructed 3D sketch of the target product to perform FEA. Therefore, we adopt this software program to perform the FEM calculation in this study.…”

New methods of optimizing the design of machines with high stiffness have attracted much attention. Conventionally, machine designers have carried out optimization by attempting to minimize static deformation or maximize static stiffness. Nevertheless, the dynamic behavior of the machine structure plays a deterministic role in the final machining precision. Therefore, we propose in this study an integral-stiffness-based optimization method for designing the optimal structure of a computer numerically controlled (CNC) grinding machine. The proposed novel optimization methodology includes a prototype designed on the basis of know-how and the determination of control parameters based on the mode shape, Taguchi's experimental method based on finite element analysis (FEA), and grey relational analysis (GRA). The target parameters in the optimization are static stiffness, first natural frequency, and dynamic stiffness. Results reveal that the optimal structure of a CNC grinding machine obtained by merely considering the static stiffness exhibits good performance when applying static forces but inferior performance when applying dynamic forces. A good optimization approach for designing a high-precision machine should integrally consider the static stiffness as well as the dynamic stiffness. With our proposed methodology, machine designers can design an optimal high-stiffness structure of a CNC grinding machine more efficiently and accurately.

The paper deals with selection and evaluation of milling strategies, available in CAM systems and applicable when complicated shape parts are produced, such as forming dies. A method to obtain samples is proposed and this stems from real forming die surface machined by proper strategies. The strategy applicability for the whole part -forming die -is reviewed by the particular specimen evaluation. The presented methodology has been verified by machining model die and comparing it to the production procedure proposed in other CAM systems.
