Abstract
The study deals with 5-axis control micromilling of such a complicated small shape as a human head by use of a diamond pseudo ball end mill. In the fields of micromachining, the milling with diamond cutting tools plays an important role due to the capability of creating 3-D complicated shapes with high accuracy. A wide variety of microstructures have been created with ultraprecision machining centers. Nevertheless, these structures seem to consist of a simple shape. Thus, the study proposes a CAM system for 5-axis control ultraprecision machining to create complicated microparts. 5-axis control micromachining of a BOSATSU was conducted to verify the practical effectiveness of the developed system. Based on the 3-D restored data of BOSATSU, the system can create the complicated statue, taking account of the collision between a tool and a workpiece. From the experimental result, it is found that the CAM system for 5-axis control ultraprecision machining has the potential of accurately producing 3-D small complicated shapes.
