摘　　要：通过对脆性材料切割工艺过程的剖析,结合感应子式步进电机的结构、原理和特点,并从电机实际应用的角度,阐述了一种节拍发生器的构造方法,在总速率可调节的基础上,引入了方式控制,即"四拍"方式和"八拍"方式,后者是前者的二分之一步距,采用"八拍"方式,可使"进刀量"更小,控制更精细,材料切面更细腻、平整,但效率相对要低些。考虑到在回程和移位过程中,并无实质性切割动作,这时采用"四拍"方式运行,可显著提高效率。因此,在硬件和软件设计时,充分考虑材料易解离的特性,采用两种方式切换的办法,既照顾到速度,也保证了质量,事实证明,这种解决方案是实用、有效的。Based on the analysis of the brittle material cutting process,combining with the structure,principle and characteristics of the induction sub-stepper motor,and from the practical application of the motor,a method of constructing the beat generator is described.On the basis of the total speed adjustablity,the mode control is introduced,namely ＂four-beat＂ and ＂eight-beat＂ modes,in which the latter is 1/2 step distance of the former.By adopting the ＂eight-beat＂ mode,the amount of feed is smaller,and the control is finer,with the more delicate and smoother material cutting aspects but relatively lower efficiency.Considering that there is no substantial cutting motion in the process of return and shift,the ＂four-beat＂ operation can significantly improve the efficiency.Therefore,in the design of hardware and software,fully considering the material characteristics of easy dissociation,using two modes to switch,it can ensure both the speed and the quality,and this fact proves that the solution is practical and effective.
