设计的三坐标数控铣床,首要是三个坐标方向的移动均由步进电机带动,主轴电机采用交流电机,所有电机均由单片机进行控制。设计主要对数控铣床的机构进行设计,了解单片机的工作原理,主要有以下几个方面:X、Y,Z工作台的传动机构设计,主要是滚珠丝杠的运用;机床整体结构的设计,了解优缺点,充分考虑主要矛盾,择优选取;单片机控制系统的设计,进一步熟悉其应用。 The design of three-coordinate CNC milling machine, the first is the movement of the three coordinate directions are driven by a stepper motor, the spindle motor AC motor, all motors are controlled by the microcontroller. The design of the main CNC milling machine body design, understand the working principle of the single-chip, mainly in the following areas: X, Y, Z table drive mechanism design, mainly the use of ball screws; machine tool overall structure of the design, understanding Advantages and disadvantages, give full consideration to the main contradictions, choose the best; microcontroller control system design, to further familiar with its application.
