1、附录 1 外文翻译（英文原文） The Surface Quantity While Machine Processes Abstract:The breakage of the machine spare parts, generally always from the surface layer beginning of.The function of the product, particularly its credibility and durable, be decided by the quantity of the spare parts surface layer to a
2、large extent.Purpose that studies the machine to process the surface quantity be for control the machine process medium various craft factor to process the surface quantity influence of regulation, in order to make use of these regulations to control to process the process, end attain to improve the
3、 surface quantity, the exaltation product use the function of purpose. Key word:The machine process the tired strength surface quantity remaining dint Text: A.the machine processes the surface quantity to use the influence of the function to the machine (A)The surface quantity to bear to whet the se
4、xual influence 1. Rough degree of surface to bear to whet the sexual influence A just process vice- of two contact surfaces of good friction, the first stage is rough only in the surface of of the peak department contact, the actual contact area is far small get in touch with the area in the theorie
5、s, at mutually get in touch with of department of peak have very big unit should dint, make actual contact area creation the mold transform, the flexibility transforms to shear to slice the breakage with of the department of peak , cause seriously wear away. The spare parts wear away and can is divi
6、ded into three stages generally, wearing away the stage, wearing away the stage normally in the early years and violent wear away the stage. The rough degree of surface is very big to the influence that the spare parts surface wear away.Say a value of surface generally more small, it wears away sex
7、more good.But rough degree of surface the value is too small, lubricant not easy storage, contact of the noodles easy occurrence the member glues to connect, wearing away to increase on the contrary.Therefore, the rough degree that contact face have a the best value, it is worth to have something to
8、 do with the work circumstance of the spare parts, working to carry the lotus enlargement, wore away the quantity aggrandizement in the early years, rough degree of surface the best value also enlargement. 2. The surface is cold to make to harden to bear to whet the sexual influence Process the surf
9、ace cold to make to harden to make rub the vice- surface layer the metals of show minute details the degree of hardness exaltation, past can make bear to whet the sex exaltation generally.But is also not cold to make to harden the degree more high, bear to whet sex more high, this is because excessi
10、vely cold make to harden and will cause the excesssive loose of the metals organization loose, even appear the crack and surface layer metals peeling off, make bear to whet sex to descend. (B)The surface influence of the quantity upon the tired strength The tired breakage that metals produce after b
11、e subjected to hand over to change to carry the lotus function usually takes place under the cold and hard layer of the spare parts surface and surfaces, therefore the surface quantity of the spare parts affects to the tired strength very greatly. 1. The surface influence of the rough degree upon th
12、e tired strength At hand over to change to carry the lotus function under, the surface part of the cave valley of the rough degree causes easily should the dint concentration, produce the tired crack.A value of surface is more big, the crackle of the surface is more deep, the crackle bottom radius i
13、s more small, the anti- tired breakage bottom ability is more bad. 2. Remaining dint, cold make to harden to the influence of the tired strength Remaining dint is very big to the spare parts influence of the tired strength.The surface layer remaining pull should the dint will make tired crack extend
14、, accelerating the tired breakage；But the surface layer remaining should the dint can keep tired crack from expand, defer tired breakage of creation. Surface the cold and hard general companion contain remaining of should the creation of the dint, can keep the crack creation from combine the arrestm
15、ent already has the crack to expand, to raise the tired strength beneficial. (C) the surface quantity to bear the eclipse influence The spare parts bears the eclipse to be decided by the rough degree of surface to a large extent.A value of surface is more big, accumulating the causticity material in
16、 the then cave valley more many.The anti- eclipse is more bad. Remaining of the surface layer pull should the dint will produce should the dint decay to open the rift , lower the spare parts to bear to whet sex, but Residual stress press should the dint then can preventfrom should dint decay open th
17、e rift . (D)The surface quantity to match with the influence of the quantity A size for be worth of surface will affect the match quantity of the match surface.Match with for the cleft, a value conference make wear away the enlargement, the cleft enlarge, the match property that break the request.Fo
18、r lead the over match, assemble process in a the convex peak of part of surfaces is push even, actual lead the amount of over let up, lowering the match the conjunction strength of the a. B. the influence surface factor of the rough degree ( A)Slice to pare to process to affect the surface factor of
19、 the rough degree 1. The knife has several shapes to reply to reflect The knife have opposite make in to give exercise in the work piece, at processed the surface to leave to slice to pare the layer to remain the area, its shape hour the knife has several the shape replies to reflect.Let up in to be
20、 partial to Cape for quantity, lord, vice- be partial to the Cape and enlarge the point of a knife arc radius, all can let up the height of remain the area. In addition, the mold that the ex- Cape that appropriate aggrandizement knife have slices by let up to pare transforms the degree, the reasonab
21、le choice lubricate the liquid and the exaltation knifes to have the mold that the blade whets the quantity to slice by let up to pare to transform and repress the knife lump, scale to stab born, also is let up a value of valid measure. 2. The property of a material of work While processing the mate
22、rial of mold , have from the knife to produced the mold to transform to the squeeze of metals, the knife that add has to force to slice the tear to pieces of scraps and the work piece separate function, making a value of surface enlargement.A material of work tenacity is more good, the mold of the m
23、etals transform more big, process the surface more rough. While processing the brittleness material, it slices the scraps to present the broken pieces form, because of slicing the scraps to collapse ground but at process the surface to leave many points to order, make surface rough. 3. Slice to pare
24、 the dosage (B)Whet to pare to process to affect the surface factor of the rough degree Just be like to slice to pare to process the surface formation process of the rough degree, formation that whets to pare to process the rough degree of surface also hour from several why plain transform with the
25、mold of the surface metals to decide of. The influence whets to pare the rough main factor of surface to have: The degree of hardness, emery wheel of a degree, emery wheel of the emery wheel fix whole, whet to pare the speed and whet to pare the path to enter to whet number of times, the work a circ
26、umference for quantity and light to enter to the speed and stalks to enter to the quantity and cool off the lubrication liquid. C. affect the factor of process the surface layer physics machine function In slice pare process, the work piece because of being subjected to slice to pare the dint and sl
27、ice the function of pare the heat, make the physics machine the function creation of the surface layer metals change, the variety of the most is variety and Residual stress s that the variety, gold that the surface layer metals shows minute details the degree of hardness organizes mutually should th
28、e creation of the dint.Because whetting to pare to process the mold produce transforms and slices to pare the hot ratio knife blade to slice to pare serious, as a result whet to pare to process to process behind the surface layer variety of above-mentioned three physicses machine function and would
29、be very big. (A)The surface layer is cold to make the hardening 1. Cold make to harden and it assesses the parameter The machine processes the process in because of slicing to pare the output mold of the dint function to transform, make the Crystal grain space distort, mutation, a creation shears to slice to slip to move, grain of Crystal grain drive make longer to turn with fiber, even broken up, these would make the surface layer metals of degree
