摘　　要：针对现有螺旋切削轨迹对曲面形状适应性较差,无法直接应用于复杂曲面的局限,提出一种基于曲面重构的螺旋曲线切削法。对于复杂曲面根据各自的特点分别采用曲面提取、修补、延伸等方法重构目标曲面,以重构后的曲面作为圆柱螺旋线的投影对象获取驱动曲线,在CAM软件中以曲线驱动方式生成螺旋曲线轨迹并进行优化。VERICUT软件仿真和实际加工的结果表明:复杂曲面采用曲面重构螺旋切削法可以获得满足高速加工要求的光顺切削路径,扩展了先进螺旋切削方式的应用范围。Against the issue that existing spiral cutting is not adaptive to surfaces and cannot be applied directly to complex surfaces,a spiral curve cutting method based on surface reconstruction is proposed. In accordance with the characteristics of complex surface,the methods of surface extraction,repair extension and so on are used to reconstruct the target surface. With the reconstructed surface as projection target of cylinder spiral curve,the driver curve is obtained. In CAM software by curve-driven approach spiral curve path is generated and optimized. VERICUT simulation and practical machining results show that complex surfaces machining using surface reconstruction spiral cutting method can generate smooth cutting path to meet high speed processing requirements and extend the application range of advanced spiral cutting method.
