摘要： A method for determining machining instructions for flank milling of a workpiece which reduces the undercut by analyzing the cutter orientation at a plurality of orientations to determine an orientation which results in a minimum undercut, smooths the machining instructions by analyzing the movement of the cutter and the workpiece in spherical coordinates and improves machinability by analyzing for near-axial conditions and selecting a modified cutter orientation for such near-axial conditions using a multi-criteria weighting factor.

摘要： A method for determining a smooth machining course for a cutting tool during machining of a workpiece. Each possible cutting tool position, with respect to the workpiece, is defined by a separate reference vector. A progression of points are defined as a tool path. A first specified portion of the reference vector will follow the tool path during machining of the workpiece. A series of reference planes are generated, each plane defines a planar set of all possible reference vector positions for each point. An acceptable range from eahc set is established which defines acceptable reference vector positions within each plane for each point. A tool course is generated, which will be followed by a second portion, distant from the first portion, of the reference vector utilizing an algorithm to minimize irregularities of the course, and to contain the course entirely within the acceptable range.
摘要翻译：一种用于在加工工件期间确定切削工具的平滑加工过程的方法。每个可能的刀具位置相对于工件由单独的参考矢量定义。点的进展被定义为工具路径。在加工工件时，参考矢量的第一个指定部分将跟随刀具路径。产生一系列参考平面，每个平面为每个点定义了所有可能的参考矢量位置的平面集合。建立了eahc集合的可接受范围，其定义了每个点每个平面内可接受的参考矢量位置。生成工具课程，其后面将是距离第一部分的第二部分，参考矢量使用算法来最小化课程的不规则性，并且将课程完全包含在可接受的范围内。

摘要： A computer generated tool path interference check including a method of checking for interference between a workpiece and a cutting tool during the numerical control machining of the workpiece by the cutter tool. Computer simulation is utilized to determine at least a portion of the workpiece that is desired to be checked for possible interference with the path of the cutter tool. The spatial relationship between the workpiece and the cutter tool during the machining are modelled as the relative positioning of the computerized images of the portion of the workpiece and the cutter tool, respectively. The relative positioning of the computerized images of the portion of the workpiece and the cutter tool are observed to check whether an interference will occur between the workpiece and the cutter tool during the machining.
