摘要
描述了鞋楦CAD/CAM的系统结构 ,并介绍了系统输出设备—数控刻楦机的加工原理。着重分析了利用直接数字定义进行加工编程的方法 ,对圆整误差和步进电机的运行频率作了特别处理 ,不仅避免了误差的累积 ,而且使步进电机始终运行在最佳工作频率段上 ,从而提高了鞋楦的加工精度和速度 。
System structure of last CAD/CAM is described. Then machining principle of system output device named numerical controlled Last Carving machine is introduced. Furthermore, we lay stress on analyzing machining programming method making use of direct numeric definition. Special disposal is taken on step error and working frequency of step motors so that not only error accumulation is avoided but also step motors always work in the best frequency range. As a result, machining precision and speed of last are both enhanced as well as step motors' working safety is guaranteed.
