| Summary: | 碩士 === 國立成功大學 === 機械工程學系碩博士班 === 98 === Turning is one of the most popular and important machining processes. Turning tools are tools which are used for turning. Turning tools are single-edge tools, and their shapes of edge are wedges. The characteristic angles which will effect cutting performance are rake angle, wedge angle and clearance angle.
First we will introduce the design of turning tools. We can built the math models of turning tools and grinding wheels by homogeneous coordinate transformation matrix. Then we’ll introduce two kinds of characteristic angles of International Standards Organization (ISO). They are tool-in-hand system and tool-in-use system. Because that tool-in-use system can reflect the condition of real process, we will analyze the characteristic angles of tool-in-use system by Fortran.
In order to grind the turning tool we have designed, we must derive the pose of grinding wheel relative to turning tool. We can derive the pose of grinding wheel relative to turning tool by homogeneous coordinate transformation matrix and surface movement law. We also use Fortran to calculate the pose of grinding wheel while grinding the face and the flank.
At last we’ll introduce the six-axis machine tool. By using modified Denavit-Hartenberg (D-H) notation and homogeneous coordinate transformation matrix, we can model the multi-axis machine tool.
