ABSTRACT
A Geometry-Based Path Optimization Approach (GBPOA) is devised to solve the motion control of the NC grinding machine. The GBPOA firstly discusses the structure of the DXF and develop a graphical recognition interface based on Java, which can read the graphical information, and can translate the graphical data into coordinate or line information (Section 2); Nextly, a zooming algorithm is proposed to solve the motion path of the tool of the NC grinding machine according to the value of grinding, and presents a path compensation algorithm to solve the
1 INTRODUCTION
A grinding machine, which is also called grinder, is used for processing components by using four procedures of kibbling, fining grinding, extract grinding and polishing. A grinder can be widely used in the areas of glass, stone, metal components, ceramic tile, and so on. It is suitable for grinding the inclined plane of the metal strip with different sizes and thicknesses, such as round edge, straight edge, and duck mouth-shaped edge type. DXF (Drawing Exchange Format) is developed by Autodesk for enabling data interoperability between AutoCAD and other programs. By reading and identifying the DXF file of the workpiece, the machine can generate the track of processing automatically.
