Abstract

The authors have been carrying out investigations on the fabrication of micro-tools such as medical devices. Until now, demands for higher productivity of micro tools have been overcome by applying molding technologies. On the other hand, demands for higher shape freedom have been satisfied by the use of cutting technologies. Generally, machining processes using the end mill are applied for creating complicated shapes. However, the minimum size of an ordinary end mill is about 0.1 mm, and grooves smaller than this size cannot be machined. In the previous report, the authors proposed a special oblique-cut mill. This tool has a very simple shape made by diagonally cutting a cylindrical tool material. It can be made even more miniature easily. However, in return for the simplification of the tool fabrication process, the cutting performance drops. To avoid this, optimum cutting conditions must be selected. In this study, the appropriate cutting conditions were reviewed based on the measurement results of the cutting force. At the same time, 3D shapes were also created using the special oblique-cut mill.
