摘 要
本文从解决步进电动机的速度控制设计的软件和硬件的问题上，使步进电动机能更好的配合数控机床的运转特点，使数控机床能发挥更好的性能。在此我基于本性质设计了一套合适的速度控制的方法，并灵活的运用数控的软件来运行数控程序来检验所设计的方法的正确与否。因此我主要从以下三方面进行介绍。 1. 数控软件的学习和应用
在这部分，主要学习Mach2软件的运行界面和操作界面的学习、软件设置的要点和电机的设置和软件的使用等一些内容；还有Mach3数控软件的综述和Mach3的控制和运行工件程序的相关知识。通过这部分学习，加深认识了数控知识的加工过程和编程的相关知识。熟悉了数控软件的安装和应用的相关操作。 2. 步进电动机的设计
通过这项内容，复习步进电动机控制方式和驱动方式、步进电动机的类型和结构、工作原理、主要特性和步进电动机的驱动控制线路的设计等相关内容 3. 步进电动机的速度控制的设计
在这部分，对步进电动机的速度控制的情况进行设计，包括步进电动机的选型、步进电动机的速度控制的软件设计和硬件设计两大方面，并且对速度控制的软件设计是运用C语言来控制，此程序比较简单，易懂，学会运用C语言来控制数控机床，也学会了C语言和汇编语言的联系。

ABSTRACT
In this paper,to solve the speed of stepper motor control software and hardware design issues,we should that stepper motor to enable better co-ordination of the functioning of the characteristics of CNC machine tools to CNC machine tools can play a better performance..I designed based on the nature of an appropriate set of speed control,and flexible use of the software to run NC,NC program designed to test the correctness of the method.Therefore,I mainly introduce the following three aspects.
1.
the application and learning of NC software
in this part,the main study is Mach2 software interface and operation interface,the key of the software settings,the settings of moter and the use of the software and other content.there are the summary of the software of Mach3 CNC,the controlling of Mach3 and the knowledge of procedures for running the workpiece.Through the part of the study,we will have a better understanding of the CNC machining process and programming knowledge.we are familiar with the installation of CNC software and the application of the operation.
2. Stepping Motor
The adoption of the content,review the driving mode and control of the stepping motor,the type and structure of stepper motor,working principle,the main characteristics of the drive and stepper motor control circuit design and other related content.
3. Stepper motor speed control design
In this part,tocontrol to the speed of the stepper motor’s design ,incloding the selection of stepper motor,the two major aspects is software design and hardware design to controlling the speed of stepper motor.And controlling the speed of software design is to use C language ,this procedure is relatively simple ,easy to understand ,it can tell us how to use C language to control the CNC machine tools, and I can understand the related of C language and assembly language links.
