摘要:
利用圆盘锯在粗加工方面具有切削深度较深和线速度大的优势,扩大石材桥式切割机的加工范围,研究其在多边形区域中的切削加工优化问题.首先,研究圆盘锯的切削几何特性,根据圆盘锯切触面特性,计算避免干涉现象的多边形内轮廓;然后,对多边形区域进行走刀方向优化,以减少进退刀次数,从而缩短加工时间;最后,为进一步缩短加工时间,采用最邻近点法对加工轨迹进行优化.通过对多边形区域加工的仿真研究,验证了提出方法的有效性.
Abstract:
Taking advantage of the deep cutting depth and high linear speed in rough machining of circular sawblade, to enlarge the machining range of stone bridge cutting machine, the optimization of machining in polygon region was studied. First, the cutting geometry characteristics of circular sawblade were studied, and the polygonal inner contour was calculated to avoid interference according to the characteristics of the circular sawblade engagement. Second, the cutting direction of polygon region was optimized to reduce the number of approach-retract of sawblade for shortening the processing time. To further shorten the processing time, the machining path was optimized by the nearest point method. The effectiveness of method was verified by the simulation study of polygon region machining.
