Mini Special Issue on Machine Tool Structure and its Design Optimization

Demands for machine tools that are highly accurate, productive, flexible, and compact have been growing in the aerospace, automotive, energy, factory automation, and other industries. Rationally meeting these severe, complex requirements has led to numerous research and development activities involving machine tools. Few machine tool technologies have been established, however, despite the machine tool industry’s long history. Within the next several years, the rapid change and enlargement of the This mini special issue on machine tool structure and its design optimization features 8 papers classified under the following themes: - Enhancing high static and dynamic rigidity - Minimizing and optimizing thermal deformation - Proposing new structural analysis methods for machine tools - Selecting and applying new structural materials to the machinetool structure - Applying new structural designs and mechanisms These papers present new design concepts, design methods, and innovative examples in machine tool development. I believe that successfully combining these core technologies will provide machine tool compatible with future manufacturing environments. In closing, I would like to express my sincere gratitude to the authors and reviewers for their interesting and dedicated contributions to this special issue.
