摘　　要

本課題結合現代教學和生產實踐的需要，從教學方式的改變（從板書課堂向多媒體教學方向轉變）和模擬調試系統帶來的方便和調試可能性出發，利用多媒體方法開發一種集教學與實踐性于一體的數控仿真軟件，使以生動的動畫形式將主軸進給系統演示給學生，使單調的數控機床課堂不再單調，使學生增強對數控加工過程和滾珠絲杠傳動原理的認識，較快的掌握所學知識。此外，進一步通過學習西門子S7-200可編程控制器，對主軸的PLC程序控制進行設計，并采用AutoCAD 2000繪制。設計的主要任務包括：完成主軸和進給動作的仿真設計及軟件設計，調試，了解主軸控制的數控PLC硬件設計。本設計主要是仿真立式數控銑床的加工過程。工作臺左右運動為X軸運動方向。工作臺底座帶工作臺前后運動為Y軸方向。Z向進給為主軸頭的上下運動，并且Z向電動機是帶制動器的，當斷電時，Z向剎緊，以防主軸頭因自重而下滑。

ABSTRACT

　　This topic combines the modern teaching and the demand of the manufacture fulfillment, adjusting to try the convenience that the system bring and adjust to try the possibility to set out from change (change toward the multi-media teaching direction from the writing on the blackboard classroom) and emulations of the teaching method, make use of the multi-media method to develop a kind of numerical control emulating software which makes the teaching and fulfillments into a integral whole. That means we will show the students a vivid animation of the feed of the spindle. It makes the numerical control lather monotonous classroom no longer monotonous, make student to build up the understanding of logarithms control process and the transitional principle of the roll bead sink pole, make students learn it quicker. In addition, by means of learning the programmable controller of Siemens S7-200, finish the design of the PLC control procedure of the spindle, and adopt AutoCAD 2000 to draw the PLC diagram .The main mission of design are as follows: Complete imitation design and software design of the spindle feed, adjust again and again, understand the numerical control of the spindle and the PLC hardware design. This design mainly is to imitate the manufacture process of the sign numerical control miller. The table moving left and right for is X. The table base with the table back and forward is Y. The spindle head going up and down is the direction of Z axis feed. The Z motor takes with brake. when the power is cut off, the motor stops in order to prevent the spindle head fall down because of self-gravity.

Key words：The numerical control machine The programmable controller of series S7-200 Multimedia of manufacture using Authorware6.5 software Soft ware to imitate working procedure of the numerical control machine The electricity principle diagram of the tool machine
