    摘要： A polishing machine is described in which a surface treatment tool is moved across the surface of a workpiece in accordance with a predefined tool-path, in order to carry out the desired treatment process. The tool-path is non-periodic and preferably pseudo-random. Various techniques are described for generating data representing the tool-path to be followed. A technique is also described for determining optimum control parameters used to control the polishing machine for a given tool-path. The surface treatment may be a shaping technique in which material is removed from the surface, or a technique for adding material to the surface of the workpiece, or a technique for modifying the surface or a region under the surface of the workpiece.

    摘要： An area machining method capable of generating tool paths with no insufficient cut portion. First, a part profile contour indicating a profile contour for area machining and various machining conditions such as tool radius, depth of cut and the like are preset. Then the outmost offset contour and other subsequent offset contours are obtained, the outmost offset contour being offset along the part profile contour by an amount of the sum of a tool radius and finishing allowance, and the other subsequent offset contours being offset repeatedly from the outmost offset contour in sequence by an amount of depth of cut in the inside direction. Next, contours of insufficient cut portions which are produced between adjacent offset contours are obtained. Subsequently, tool paths each of which connects between offset contours and between an offset contour and a corresponding insufficient cut portion contour are outputted. At this time, insufficient cut portion contours are added to tool paths by changing a tool path to an insufficient cut portion contour if the insufficient cut portion contour is present near the current path while outputting an offset contour as a tool path.

    摘要： Improvements in a high speed smooth tool path is presented where the high speed smooth tool path to be used for primarily finishing for finishing any type of walls (negative/positive drafted) for any given bounded region be it 3, 4, 5, . . . n sided shape. The tool path incorporates a combined strategy for finishing the walls while removing any excess material leftover from a previous larger diameter cutter. This tool-motion can be utilized for roughing the regions by approximating the walls by offsetting the regions inwards. The finished boundaries are offset inwards and then cut using these methods. This is optimized as opposed to moving the cutter at a consistent speed in the cutting path. This is performed to eliminate the wasted tool-motion to the maximum extent. This technique is implemented for roughing any closed or open bounded areas regardless of the walls being straight, drafted (negative/positive or both).

    摘要： A machine tool 10 to fashion objects from blocks of material having a material-remover 16 able to move in at least two degrees of freedom and having the material 18 controlled by processing circuitry. The processing circuitry 18 determines a path along which the material-remover 16 should move, allowing the depth of a cut made by the material remover to vary. The movement of the material-remover 16 is so controlled to improve bulk material removal when compared to prior art machines.

    摘要： A cutting shape (Q1) is approximated to a polygonal shape (Q3). Division points are obtained by dividing line segments linking each vertex of this polygonal shape (Q3) with the cutting start point (PS1) by the same number. Corresponding division points on each line segment are then linked to obtained a plurality of polygonal closed paths (PH2-PH4). Here, the innermost closed path (PH2) is devised such that at least a portion thereof passes outside the cutting starting hole centered on the cutting start point (PS1).
