    Abstract: The present invention discloses a five-axis flank milling system for machining a curved surface and a tool-path planning method. The method generates a tool path comprising a series of cutter locations by optimization with minimizing machining errors. The tool path planning method includes a reciprocating tool path planning method and a multi-pass tool path planning method. The reciprocating tool path planning method eliminates the “forward only” limitation. The tool is allowed to move backward in certain regions, producing smaller machining errors compared with forward only cutter movement. Furthermore, the multi-pass tool path planning method computes various tool paths applied to finish milling multiple times. Each path can be chosen to be generated by minimizing undercut error, overcut error, or the total machining error. The machining errors are reduced in a progressive manner, resulting in better machining quality than single pass tool path.

  • Patent number: 8010328
    Abstract: Provided is a method performed on a processor for simulating the milling of an object by moving a shape along a path intersecting the object. A composite adaptively sampled distance field (ADF) is generated to represent the object, where the composite ADF includes a set of cells. Each cell in the composite ADF includes a set of distance fields and a procedural reconstruction method for reconstructing the object within the cell. The shape is represented by a shape distance field. The path is represented by a parametric function. A swept volume distance field is defined in a continuous manner to represent a swept volume generated by moving the shape along the path according to a swept volume reconstruction method which reconstructs the swept volume distance field at a sample point. The composite ADF is edited to incorporate the swept volume distance field into the composite ADF to simulate the milling.

  • Patent number: 7184854
    Abstract: A machining data generator generates NC machining data specifying machining operations for shaping the external shape of a piston. The machining data generator uses a machining data sheet (provided by a spreadsheet software) describing noncircular part shape data on the shape of a noncircular part and condition data (machining condition data and shape data on shapes of parts other than the noncircular part necessary for shaping the overall shape of the piston). The machining data sheet is prepared beforehand. A machining data generation program reads the machining data sheet in step S4, recognizes directives “start cell” and “end cell” defining a cell region and described in the machining data sheet and fetches matrix data from the cell region in step S5, and fetches condition data other than the noncircular part shape data from the machining data sheet, and calculates NC machining data to be given to a NC machine tool on the basis of the condition data and the noncircular part shape data in step S6.
