Editorial:: Special Issue on \Multiaxis Control and Multitasking Machine Tools vspace{15pt}\; vspaceYoshimi Takeuchi, pp. 77-77; Machine tools using numerical control (NC) devices are typical mechatronics products and a powerful way to automate plant production.
The introduction of multiaxis control and multitasking machine tools to workshops is growing to meet the requirements of highly efficient, precision machining of a variety of complex products and mold dies. The increase in the number of control axes and multitasking capability in one chucking process enable machine tools to manufacture complex products efficiently and accurately.
Given the strong attention and interest multiaxis control and multitasking machine tools are attracting, it is about time to introduce the current state of the art of these tools and their practical and applicable technologies, especially in Japan. This special issue covers the development of 5-axis control machining centers, machine tools having multispindle heads with 5-axis control, 5-axis control CAMs, accuracy evaluation for 5-axis control machine tools, and more.
We thank the authors for their interesting papers to this special issue, and are certain that both general readers and specialists will find the information they provide both interesting and informative.; Full Text (PDF21KB)
