3、that utilize both mechanical and electronic dis- </p><p>　　cipplines. Mechatronics,however ,specifically refers to a multidisciplined ,integrated approach</p><p>　　to product and manufacturing s

4、ystem design .It represents the next generation of machines,</p><p>　　robots ,and smart mechanisms necessary for carrying out work in a variety of environments-</p><p>　　primarily ,factory autom

5、ation ,office automation ,and home automation as show in Figure 1.</p><p>　　By both implication and application ,mechatronics represents a new level of integration </p><p>　　for advanced manufac

6、turing technology and processes .The intent is to force a multidisciplinary </p><p>　　approach to these syetems as well as to reemphasize the role of process understanding and </p><p>　　control

7、.This mechatronic approach is currently speeding up the already-rapid Japanese process</p><p>　　for trasforming ideas into products .</p><p>　　Currently ,mechatronics describes the Japanese prac

8、tice of useing fully intefrated teams </p><p>　　of product designers ,manufactring, purchasing, and marketing personnel acting in concert with</p><p>　　each other to design both the product and

9、the manufacturing syestem.</p><p>　　The Japanese recognized that the future in producdtion innovation would belong to those who </p><p>　　learned how to optimize the marriage beween eletronic a

10、nd mechanical systems.They realized,in</p><p>　　particular ,that the need for this optimizatong would be most intense in application of advanced manufacturing and production systems where artificial intellig

11、ence ,expert</p><p>　　systems ,smart robots, and advanced manufacturing technology systems would create the next </p><p>　　generation of tools to be used in the factory of the future.</p>

12、<p>　　From the very beginnings of recorded time ,mechanical systems have found their way into every</p><p>　　aspect of our society .Our simplest mechanisms ,such as gears ,pulleys, springs,and wheeles.

13、</p><p>　　have provided the basis for our tools .Our electronics technology,on the other hand ,is completely</p><p>　　twentieth-century ,all of it created within the past 75 years.</p>&l

14、t;p>　　Until now ,electronics were included to enhance mechanical systems' performance ,but the </p><p>　　emphasis remained on the mechanical product .There had never been any master plan on how the &l

15、t;/p><p>　　integration would be done .In the past ,it had been done on a case -by-case basis .More recently</p><p>　　,however,because of the overwhelming advances in the world of electronics and it

16、s capability </p><p>　　to physically simplify mechanical configurations ,the technical community began to reassess</p><p>　　the marriage between these two disciplines.</p><p>　　The

17、most obvious trend in the direction of mechatronic innovation can be observed in the </p><p>　　automobile industry .There was atime when a car was primarily a mechanical marvel with a</p><p>　

18、　few electronic appendages.</p><p>　　First came the starter motor ,and then the generator ,each making the original product a bit </p><p>　　better than it was before .Then came solid-state elect

19、ronics,and suddenly the mechanical marvel</p><p>　　became an electro-mechanical marvel .Today's machine is controlled by microprocessors ,built by</p><p>　　robots ,and fault-an-alyzed by a c

20、omputer connected to its "external interface connector".</p><p>　　Automotive mechanical engineers are no longer the masters of their creations.</p><p>　　The process that describes the

21、evolution of the autimibile is somewhat typical of other </p><p>　　productds in our society.Electronics has repeatedly improved the performance of mechanical </p><p>　　systems ,but that innovati

22、on has been more by serendipity than by design .And that is the essence</p><p>　　of mechatronica the preplanned application of ,and the efficient integration of,mechanical</p><p>　　and electron

23、ics technology to create an optimum product.</p><p>　　A recent U.S. Department of Commerce report entitled "JTECH Panel Report on Mechatronics </p><p>　　in Japan"compared U.S and Japan

24、ese research and development trends in specific areas of mechatronics </p><p>　　technology.Except for afew areas ,the technology necessary to accomplish the development of</p><p>　　the next gene

25、ration of systems embodying the principles of mechatronics is fully within the </p><p>　　technological reach of the Japanede .</p><p>　　Comparisons were made in three categories :basic research

26、,asvanced development, and product</p><p>　　implementation.Except for machine vision and software ,Japanese basic research was comparable </p><p>　　to the United States,with the Japanese closing

27、 in fase on macchine vision system technology.</p><p>　　Japanese artificial intelligence research is falling behind ,primarily because the Japanese do</p><p>　　not consider it an essential ingre

28、dient of their future systems ,they appear capable of closing </p><p>　　even that gap,if required .In the advanced development and product implementation areas,Japan</p><p>　　is equal to or bett

29、er than the United States,and is continuing to pull ahead at this time .</p><p>　　The Department of Commerce report concleuded that Japan is maintaining itsposition and is</p><p>　　in some cases

30、 gaining ground over the United States in the application of mechatronics .Their</p><p>　　progress in mechatrinics is important because it addresses the very means for next generation</p><p>　　o

31、f data -driven advanced design and manufacturing technology. In fact ,the Department of Commerce </p><p>　　repert cincludes that this has created a regenrative effect on Japan's manufacturing industries.

32、</p><p>　　TO clese the gap ,we will need to go much further than creating new tools .If we accept</p><p>　　the fact that mechanical systems optimally coupled with eletronics components will be t

33、he wave</p><p>　　of the future ,then we must also understand that the pipple effect will be felt all the way back</p><p>　　to the university,where we now keep the two disciplines of mechanics an

34、d eletronics separated and</p><p>　　allow them to meet only in occasional overview sessions .New curricula must be create fir a new</p><p>　　hybrid engineer a mechatronics engineer .Only then ca

35、n we be assured that future generations </p><p>　　of product designers and manufactuiing engineers will full seek excellence in these new techniques.</p><p>　　We need to rethink our present day

36、approach of separating our engineering staffs both and</p><p>　　from each other and from the producting engineers .Living together and communicating individual</p><p>　　knowledge will be the ke

37、y to optimum designs and new product development .</p><p>　　The definition of mechatronics is much more significant than its combined words imply .</p><p>　　It can physically turn engineering a

38、nd manufacturing upside down. It will change the way we </p><p>　　design and produce the next generating of high technology products.The nation that fully implements </p><p>　　the rediments of m

40、gt;<p>　　Mechatronics may sound like utopia to many product and manufacturing managers it is often presented as the solution to nearly all of the problems in manufacturing . In particular ,it promises to increase

41、productivity in the factory dramatically.Design changes are easy with extensive use of mechatronic elements such as CAD; CAP and MIS systems help in scheduling ; and flexible manufacturing systems ,computer-aided design

45、t;/p><p>　　Typically , the throughput for a set of machines in a mechatronics system will be up to three times that for the same machines in a stand-alone job shop environment . The mechatronic system achieves

46、 high efficiency by having the computer schedule every part to a machine as soon as it is free , simultaneously moving the part on the automated material handling system and downloading the appropriate computer program

47、to the machine . In addition , the part arrives at a machine already fixtured on </p><p>　　Reduced Capital Equipment Costs</p><p>　　The high utilization of eqipment results in the need for f

48、ewer machines in the mechatronic system to do the same work load as in a conventional systenm . Reductions of 3:1 are common when replaceing machining centers in a job-shop situation with a mechatronic system. </p>

49、;<p>　　Reduced Direct Labor Costs </p><p>　　Since each machine is completely under computer control ,full-time oversight is not repaired . Direct labor can be reduced to the less skilled personnel

50、who fixture and defixture the parts at the work station ,and a machinist to oversee or repair the work stations ,plus the system supervisor . While the fixturing personnel in mechatronic environments require less advance

52、;　　The reduction of work –in-process in a mechatronic system is quite dramatic when compared to a job-shop environment . Reductions of 80 percent have been reported at some installations and may be attributed to a variet

53、y of factors which reduce the time a part waits for metal-cutting operations. These factors include concentration of all the equipment required to produce part into a small area ;reduction in the number of fixtures requi

57、or more machines fail . This is accomplished by incorporating redundant machining capability and a material handling system that allows failed machines to be bypassed . Thus , throughput is maintained at a reduced rate.&

66、in office automation and home automation .</p><p>　　System Concept </p><p>　　Mechatronic production systems include all aspects of product design , manufacturing , and plant management , in a

70、“give the customer what he wants ,not what you think he wants .”</p><p>　　Sharing the design process with customer is an interesting process that , when considered as part of the mechatronic philosophy , b
