Machining Center

The theory of structural dynamic analysis is put forward firstly. Then the dynamic performance of HMC80 high-speed precision machining center column is analyzed by means of finite element method. The dynamic performance of the column is analyzed using structural dynamic optimization theory and variation analysis with the thickness of wall plate and the inner rib plates as the parameters thirdly. Based on the analysis results, the structure optimization scheme of the column is obtained. The structure optimization scheme is analyzed and the analysis results show that the dynamic performance of the column optimization scheme is improved obviously.

Machining Center

The high-speed electric spindle is the key part of the machining center which performing high speed precision machining. In order to ensure the electric spindle running under the smooth and steady state, it is necessary to prevent and discover the abnormities during the running process of the electric spindle by the experimental test and analysis. In this paper, the vibration order analysis method combined with the experimental modal test is utilized to measure and diagnose the abnormities of a high speed electric spindle.

Development Approach

Manufacturing fields in high-income countries have tended to pursue high quality and high productivity together. In conventional machining, however, machine tools, cutting tools, machining process, and measurement technologies have progressed individually rather than together -- mainly due to the production industry configuration. With society’s needs growing and diversifying, however, development approach that combines distinct technologies without integration no long ensures competitiveness. In a world where knowledge and ideas regarded as know-how and used implicitly, knowledge and ideas should be integrated into explicit software with adequate hardware. The important issues are as follows:<br /> (1)Process monitoring technology providing sufficient information for systems to make decisions based on economical investment<br /> (2)Process control technology based on a deeper understanding of processes themselves and of the nature of control<br /> (3)Motion control technology for precise, high-speed, versatile movement in support process control This special issue provides the latest topics related to these issues, and we are sure readers will enjoy reading about and sharing ideas toward a new machine tools and manufacturing technology paradigm. We thank the authors for their contributions to this special issue and the reviewers and editors for their ongoing efforts.
