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
