Metalworking exercitation is class of base of a practice, it is enginery each major and other a lot of engineering course are professional material of student learning project and the course such as mechanical production foundation are indispensable build a course first, dispute machine kind the important practice education segment in planning about professional education. It to fostering us start work ability has very great sense. And the mechanical workmanship that can make we understand a tradition and contemporary machinery make a technology. Regard automation as a professional student, it is admittedly important to learn academic knowledge, but start work ability also is crucial, present a lot of undergraduates, come from urban classmate especially, at ordinary times the chance that oneself start work is little, the ability that start work is poor, the society is right after suiting very hard the demand of overall person with ability. And metalworking exercitation course is us the student of these manage engineering course brought the opportunity that takes exercise actually, let us walk out of classroom, in the workshop of various workpiece and machine, oneself start work, kiss body check, these are tremendous to our help. Acknowledgment school offers such opportunity for us, also thank the teachers that hardship is guided and coach we learn at the same time. Put on military uniform again we, become a campus to shine in together beautiful scenery, still remember first time, the person that we are taken is curious and excited mood, face start of base of exercitation of Xiamen University metalworking, imagine him move finishs the joy that workpiece machines with one's own hands. However, what time passes is really fast, before you can say Jack Robinson, the metalworking exercitation of 18 6 weeks class hour had ended brief session, in the day when blue collar, we had had hardships, had had awe-stricken, but we are harvested more be happy He Baogui start work experience. With the teacher, classmates gather in the workshop the sort of kind, the sort of experience, the memory that is the eternity in my life. During the exercitation, I joined lathe operator early or late, solder, digital line cut, benchwork, tear open outfit, milling, from which I acquired a lot of precious things, it let me acquire the thing that book does not go to school, those who enhance oneself start work ability. Lathe work of the 1st course, first time metalworking jackarooed on July 1, 2010, feel very fresh to us, one big early, our prep against faces south, in spirits ground sets out to exercitation base, attend a class ahead of schedule today, mr. Deng Guming explains the meaning that metalworking jackarooes to us, curricular arrangement, and the safe problem in exercitation process. Overall and character, the exercitation class on us slants apparently little, this likelihood because the reason of field, after believing nevertheless, exercitation time of the student is met increase gradually. Next, the teacher introduces all sorts of cutting tool in detail for us one by one again, workpiece, the relevant knowledge of lathe, although these knowledge are right we are very unfamiliar, but the teacher's patience explains, let us began to generate interest, those who listen is more serious also, because these knowledge are the basiccest,also be most the most important, next we according to in group, guide by different teacher enter respective type of work in production. My cent is in the 3rd group, the type of work that contacts above all is lathe work. Lathe work is the surface that the shift of the whirl that uses work on lathe and cutting tool will come to machine all sorts of swing tower, include: Whorl of taper seat of inside and outside, inside and outside, end panel, groove, the cutting tool that lathe work place uses has: Lathe tool, boring cutter, broach, when the car sells treatment, the motion that the whirligig of workpiece gives priority to, cutting tool moves for feed relative to the transverse or fore-and-aft shift of workpiece. Facing giant lathe, we besides curiosity, to it very unfamiliar, the teacher gives us the name of each attentive parts that explain lathe and operation detailed rules, we are familiar with car head gradually, feed box, take knife case, the control of the main part such as tray, the teacher asks we do not open motor-car bed first, even if transverse hand is moved,the key undertakes feed practices. The requirement reachs action of advance and retreat accurate, freely, and should accomplish feed movement slow, even, successive. To the exercise can drive after certain level, till every operation undertakes we are familiar with, next, the teacher asks we make the circle outside taking knife car automatically, every time the diameter of the car is 20 Mm, so cutting tool can advance only 10mm, want adroitness control to handle order: Aim tray workpiece zero first, retreat knife adjustment cutting tool to want ongoing 10mm, drive, wait for knife advancement to arrive when 3/4, instead hand moves a knife to arrive exact position, retreat a knife to jockey. Through a few training, we had been familiar with an operation. As a result of the reason of time, we can give this job only, what nevertheless we do is very serious, also see the labor gain that oneself get on in so giant machine tool for the first time, in the heart very glad really, believe oneself are in next the meeting in the exercitation does better more! The 2nd class solders, the electric spark that Ceng Mo saw several times twinkle in construction site on July 8, 2010, I know that solders namely, this class, we also want what bring into contact with makes a lot of classmates awe-stricken to solder, thinking it is very easy that the operation rises originally, however the fact is not however in that way, it is difficult to want than what I imagine much. Today, the relevant operation that to us detailed introduction solders mixes the teacher a few notes, solder the light of the odour of a generation and dazzling is harmful to human body, we should know him protection when the operation, put on coverall, take veil. From the teacher in explaining, I understand: The angle of welding rod is in commonly 70 go to eight, carry speed, the requirement is divide evenly of course fast, in be being operated actually however, we often are unhappy slow, maintain divide evenly very hard fast, the result that comes out because of this solder is very slack, some local retention period are brief good without solder of course, still have flaw, the place with long retention period, the defect that is shown by solder via often can appearing, appeared flaw; The height of welding rod asks to maintain in 2 to 4 millimeter, be in however him inchoate moment also is flaw 100, because carrying while, welding rod is being decreased ceaselessly short, because this wants the ceaseless original height that changes welding rod, this control rises to have some of difficulty, take off arc easily high, and low adhere easily. Every classmate tries 3 welding rod, him person that look the appearance of all kinds of strange things that solder comes out, in the heart that anxious, solder for many times in oneself fortunately hind, begin to find feel slowly, pass with the achievement of fine in final exam. Solder through this, we had mastered the knowledge that spot welding receives, but want worker of take office course of study in that way standard, need the exercise that we relapse, skill comes from practice. Although,solder very tired, very dangerous also, but we had soldered with one's own hands, had experienced, later the opportunity is carried out well again. Cut of line of the 3rd class, on July 15, 2010 today, one of the most advanced type of work in the workshop that we should undertake -- treatment of cut of line of electric spark numerical control. This is more unfamiliar to us, as a result of its are magical and accurate operation, let us generate huge interest. Because this is method of a kind of non-traditional machining, equipment is more precious, operation method is relatively complex also, in case the operation is undeserved, the electrode silk that undertaking cut treatment is used will be broken, produce person and equipment accident even, so the teacher introduces the 4 big component of the machine tool and its main effect in detail to us before begin today: .

Orgnaization of silk of part of numerical control device, machine tool, carry, , filar wearing, , procrastinate board (direction of X, Y) in the computer control falls, make shape harmoniously motion, lathe bed (secure system of each machinery, transmission) composition; High frequency strong power source, action has 2 (offer time cutty pulse to discharge) , (of working fluid system.

Insulation action; Discharge bits and cooling action) . Processing technique of cut of numerical control line is to should use the program that has written, rely on electrode silk discharge to come cut all sorts of little work, the work that we should do designs workpiece namely, had set work, to good knife, other issue gives computer was finished. Accuracy is tall, rate is slower nevertheless, because we have the time morning only, the teacher sets an example to draw the graph that wants treatment on computer to us directly, input its cut machine tool, make its automatic cut. The so much operation on device of numerical control of the person that look is pressed twist, do not know to do it from where really temporarily, the teacher relapses explain to us, just be familiar with a few main operations gradually. We are called from inside graphical library finally give " heart " graph, send cut the system its, add cooling fluid during cut, the scintilla that part of the day of steel wire of the person that look gives, the outline of workpiece is clearer and clearer, can't help of exclaim project technology advanced, when designing a graph as a result of oneself regrettablly, did not adjust good shrink enlarge is small, ended up with a very fine writing, with the classmate of the group very happy. Although be in exercitation process very painstaking, but strong however denounce is worn our melting smile. Benchwork of the 4th class, on July 22, 2010 today, we should undertake the tireddest a type of work, benchwork, the teacher tells us, benchwork is labour of a complete armrest will make all sorts of parts, be can exercise a person to start work most of ability, a few great engineers, they take themselves seriously to be in very much of benchwork respect take exercise, and can very good control benchwork. Heard the teacher's word, we feel benchwork is a very marvelous type of work immediately, the experience should go well during the exercitation. Benchwork is in alone exercitation workshop undertakes, what we face is 3 giant workbench, a lot of table vice were installed above, use clip all sorts of workpiece. There are various tools on left, include: All sorts of hand hammer, handsaw, files, tap, front tooth, and underline a tool to wait. The teacher introduced metalworking to jackaroo to us all sorts of knowledge, as a result of the reason of working hours, the teacher asks we are done only today the basiccest curium and grind, I still am interested in these quite, can master it truly nevertheless, still want to give oneself long effort. From the basiccest beginning, ourselves elected some of board, design the figure that oneself want, five-pointed star goes up with powdery strokes on my preexistence armor plate, place it on vice, the line that with handsaw alignment has drawn has rhythm ground to move back and forth, this is one is compared kind physical strength is vivid, mastering good posture and skill still is laborious really, below the teacher's guidance, we begin to experience " the rope curiums wood is broken " feeling, preexistence curiums on initiative line give small mouth, next the right hand handholds curium handle, left hand tiger's mouth-jaws of death is pinned curium front, divide evenly fast pull use saw blade, the model in looking at him memory gradually clarity rises, happy drive of the heart the ache besides the arm. It is to want the end panel to curiuming to undertake file is versed in next, use rasp first, reoccupy fine file, the 5 horn heart that designs oneself is done brilliantly. Although benchwork is very tired, look at the achievement that oneself work hard hard nevertheless, feeling of a kind of achievement arises spontaneously, had struggled when oneself, pass hard, no matter encounter what difficulty, oneself are faced can hopefully, believe oneself, can go certainly! The 5th class is torn open outfit, metalworking jackarooed on July 29, 2010 now, the dirtiest vivid estimation should calculate tear open installed, two hands are stained with oily dirty, this is the first impression that Bencishi reviews. Tear open nevertheless installing is process of a more important field trip, the interior construction that it can assist us to understand all sorts of parts of an apparatus deeplier and working principle. The main shaft box that the job that the teacher gives us today is pair of lathe and tray undertake tearing open installing, the effect that knows each parts and the working principle with each in-house work. We are divided into a few groups to undertake, I enter of travel is pair of tray to tear open above all outfit, dropping screw to coming back simply do not have any problems, nevertheless the problem depends on how finding the breach that can disassemble, the iteration in oneself observes and the teacher's guidance falls, we a complete tray complete dismember, internal composition more is to rely on gear to come of transmission, if insert steel bar to wait,having some of additional design is to increase the firm sex of tray, reduce the friction of parts interior effectively through lubricant device, increase use flexibility, fumble carefully in oneself below, installation rises true and relaxed. The 2nd work that we do is to tear open box of outfit main shaft, the course that tear open is apparent much simpler than the first, take off main shaft box to build, present the one annulus before us to cover the gear of one annulus and pitch-black benzine, start work in everybody's collective discuss to fall with observation, be clear about understanding of this bloodcurdling device eventually, as handle of the right hand side jolty, gear can have 6 kinds job state in all, smoke gasoline tank to be below the roll of gear, compress cylinder, pump oil from one's store of valuables send, have the effect of lubricant gear, can realize petrolic to be used circularly again. Tearing open the process of outfit is more as dry as a chip, but study parts of an apparatus jointly together with the classmate, collective breath petrolic blames flavour, collective happy to realise the working principle of a certain link. Milling of the 6th class, on August 5, 2010 milling, regard the last metalworking of my university phase as exercitation type of work, oneself have kind of ineffable feeling, last class should throw him the attention of 100% , because had been done not have,issue section class. Today, the teacher introduced the sort of the relevant knowledge of milling and milling machine in detail to us, principle and use method. Milling machine cent is vertical and horizontal two kinds, the work that wants treatment is placed on the smooth clamp of workbench, rely on feed dial to undertake to its transverse, fore-and-aft the control that reachs fluctuation motion, and cutting tool maintains do not move, this and lathe just contrary. After the working principle of familiar milling machine and operation, the job that the teacher gives us is a cylinder cutting becomes square travel, the side of requirement square is long for 29MM, we place workpiece on smooth clamp, turn rotary table will dominate the niche of smooth clamp next, when cutting tool basically when centre position, begin pair of knives, after be opposite, turn two rounds according to requirement set dial half, treatment workpiece can rise 6.

5MM, can begin to process work, not a little while time, below the cutting of cutting tool, the square of a standard was born on milling machine. The treatment efficiency of milling is very tall, it is the commonly used tool that metallic cutting machines. Aborning is having wide application. Him hope can have more opportunities to attend the exercitation of this respect in the following practice, ceaseless him buildup start work ability. 6 the last word is short weeks trainee ended alive, the travel of our blue collar also drew a satisfactory full stop, acknowledgment school offers such opportunity for us, should thank our teacher deeply more at the same time, from them in teaching by personal example as well as verbal instrution, we benefit a lot, whats do not understand from inchoate, know to the profundity of all sorts of machines to now, master a few main operations. This second metalworking jackarooes -- your person hard dismiss from one's mind. 6 metalworking exercitation brings us, it is those operation skill of our place bring into contact with not just, also be a few kinds of ability that ask through place of a few type of work we take exercise not just, more according to oneself cases after needing our everybody to end in the exercitation go comprehending, go thinking over, diligent Shi Zimian, harvest somewhat, make this the exercitation achieved his real goal.
