一、概述 迄今为止在世界各地已经出现的手动仿形雕刻机产品不下三十种。我们对这些不同种类的手动仿形雕刻机进行分析后发现它们都存在一些不足之处: (1)自由度数目较少,不易于实现复杂产品的加工; (2)操作部件惯性大,操作十分费力,雕刻效率较低; (3)采用蜗轮蜗杆传动装置实现工件与模具的同步回转运动, First, an overview So far in the rest of the world have emerged manual copying engraving machine products no less than thirty. We analyzed these different types of manual copying engraving machine and found that they all have some shortcomings: (1) fewer degrees of freedom, not easy to achieve the processing of complex products; (2) operating inertial inertia, the operation is very Laborious, less efficient carving; (3) the use of worm gear to achieve synchronous rotation of the workpiece and the mold,
