The software can design many conventional type of cam , concluding cam - plate with middle follower , cam - plate with offset follower , cylindrical cam , dividing cylindrical cam , and cylindrical cam with space curve , etc . in forming working curves of cam - plate , used the approximation by arcs which can lessen the nodal points on curves of cam uttermostly in same error , so it reduce the computation time and relieve the chattering of principal axis . in former times , to cam mechanism , the follower only has one direction motion
本软件可以设计的凸轮类型较多，包括了对心移动从动件盘形凸轮、偏置移动从动件盘形凸轮、圆柱凸轮、圆柱分度凸轮和空间曲线柱形凸轮等，其中对盘形凸轮的工作曲线采用了难度较大的圆弧逼近算法和等误差算法，这样就可以在相同的允许误差内最大限度的减少生成曲线的节点数，减少计算时间，同时可以大大减轻加工中的振动现象。
