在机械制造行业中,普遍采用靠模加工方法加工盘形凸轮、单体活塞环等平面曲线外廓零件。该加工方法的关键之一,是设计制造正确外廓形状的靠模凸轮。因此直接计算出靠模凸轮外廓形状,不论对评定或修正靠模凸轮都是十分必要的。下面以反靠法为例,用解析法建立数学档型,应用计算机计算靠模凸论以一定角度步长变化的极角所对应的极径值。 In the machinery manufacturing industry, commonly used by the processing method of processing disc cam, single piston ring and other parts of the plane curve contour. One of the keys to this machining method is to design and manufacture a cam with the correct profile. Therefore, the direct calculation of the shape of the profile cam profile, regardless of the assessment or correction cam is very necessary. The following to counter-law as an example, the use of analytical methods to establish the mathematical profile, the use of computer calculations by the convex model to a certain degree of angle of the polar angle corresponding to the diameter value.
