文档介绍：基于PC的二维数控实验台的设计与实现
[摘要]
本论文课题是基于PC机的二维数控实验台的设计与实现,目的是为了了解二维数控实验台的设计方法和特点,以及如何用PC机控制数控实验台的动作,将所学到的理论知识运用到实际设计之中,理论和实践相结合。
本文首先通过对怎样用PC机控制数控实验台的介绍加深人们对PC机控制的了解。然后对实验台进行分析,最终确定PC机对数控实验台的速度与位移的控制。
在对实验台机械结构进行设计的过程中,主要对滚珠丝杠螺母副和电机进行了计算、选型、校核,确保了机械传动部件的精度和刚度,使之满足系统的要求:通过计算,选择了步进电机驱动。
本设计结合机电一体化课程教学环节需要,设计用微型计算机作为控制系统的X-Y工作台。通过论述X-Y工作台机械结构设计和控制电路接口设计,,使操作更简便。

PC-based two-dimensional test-C Design and Implementation
Abstract:
In this paper, the subject is based on the PC of the two-dimensional test-C Design and Implementation, In order to understand the purpose of test-bed two-dimensional numerical control design method and characteristics of, PC control, as well as how to test the action of NC, Learned to use the theoretical knowledge to practical design, combination of theory and practice.
In this paper, through the PC to control how the introduction of NC test-bed to deepen people's understanding of PLC control. And then an analysis of the test-bed, CNC PC to finalize the test-bed for the speed and displacement control.
In the mechanical structure of the experimental design process, Vice-principal of the ball screw and motor calculated, selection, checking to ensure the accuracy of mechanical ponents and stiffness, So as to meet the system requirements: through the calculation, select the stepper motor driver.
Originally bining electromechanics' integrated course teaching link to need , design the X-Y workstable which use puter as the control system.. Through expounding the design of the of the X-Y workstable’s mechanical structural and the interface of the control circuit, have explained the generality and the key technology in the electromechanical integrated design. And design one control interface of the experimental systenm with the VB sofeware, which make operating more simple and more convenient.
Key words:The X-Y workstable;puter;electromechanical integrated design
