使用高速銑削進行零件精加工

零件精加工是一種基於曲面的演算法. 對於多曲線模型, 應盡可能減少銑刀的升程. 這就要求產生的銑刀路徑在相同的角度範圍內或需要軸向和徑向不同的餘量.
The parts adopt the strategy of contour CNC machining. Contour CNC machining can generate tool paths of different heights according to a series of curved surface contours formed by the curved surface shape. Like horizontal slicing of part geometry, this machining strategy is the optimal strategy for semi-finishing and finishing of steep areas. By limiting the angle range of contour CNC machining (30°～90°), steep areas are processed, and other flat areas can be processed by other more strategies.

In addition to the strategy of using contour CNC machining, solutions for horizontal machining and parallel machining must also be used. The horizontal processing strategy is to automatically detect all flat areas and offset in the height direction for milling. This machining strategy uses tools with a smooth path similar to roughing. The tool path connection is also the same as rough machining, and it can carry out contour inclined feed, spiral cutting and smooth tool path connection path. If the user requests to process these flat areas multiple times, the result can be obtained by setting different Z offsets. Parallel CNC machining is one of the most widely used finishing strategies. The linear tool path is used for semi-finishing and smooth area finishing after roughing. The tool path is parallel to the X and Y planes and changes with the Z value of the surface. You can select the direction and step distance of the horizontal area. The cross path is 90° from the parallel path to process all areas. The adoption of this strategy can avoid frequent changes of direction.
