Pro/E is in design of figuration lathe tool and the application in making

Model of semifinished product of 1 scale cutting tool is used build hypostatic feature to command " Extrude of → of Solid → Protrusion " command, view is planar before (Front face) for plot plane, scale gives semifinished product of figuration lathe tool fore-and-aft and sectional graph, among them before γ of the horn before knife face and horizontal included angle are equal to cutting tool (γ of the horn before taking cutting tool here is 15 ° ) , α of the horn after face of the knife after making at the same time and perpendicular direction included angle are equal to cutting tool (α of the horn after taking cutting tool here is 10 ° ) , if pursue 2 (A) be shown. The others dimension can decide according to actual condition, the drawing length of cutting tool semifinished product is equal to the length of workpiece. If the three-dimensional model of cutting tool semifinished product pursues 2 (B) be shown. (A)(b) pursues semifinished product of 2 figuration lathe tool pursues 2.

2 establish model of cutting tool substance above all according to be being machined spare parts outline gets curve of blade of lathe tool cutting. If the graph is shown 3 times, inside horizontal form of scale work check pursues, each dimension and part drawing size are same, the distance of blade of the cutting on axes and lathe tool semifinished product is equal to workpiece the smallest circumferential radius. Use build curved surface feature to command Surface → Revolve commands, obtain by curved surface of outline of treatment spare parts. Graph the scale effect that form of 3 work check pursues by build hypostatic feature to command " Use Quilt of → of Solid → Cut " , cut cutting tool semifinished product with workpiece outline curved surface, such advanced knives can get curve of form of cutting tool blade on the face. By " Projected of → of Datum → Curve " command, build curvilinear feature with umbriferous means, curve of form of blade of choice cutting blade is umbriferous curve, it is umbriferous face with underside of cutting tool semifinished product, choose Along Dir option, with cutting tool a crest line serves as umbriferous method, curve of form of cutting blade blade umbriferous go up in the underside of cutting tool semifinished product, if pursue,as a result 4 are shown. Graph the formation of form of blade of 4 cutting blade is used build hypostatic feature to command " Extrude of → of Solid → Cut " , underside of choice cutting tool is plot plane, use Edge command of → of use Geom Tools chooses umbriferous curve to be analyse tangent, cut the spare part of cutting tool semifinished product, can get the three-dimensional and hypostatic model of lathe tool of arris form figuration from this. 2.

3 cutting tool are repaired because form is in when part of B-c of treatment spare parts, the 0 ° of ＝ of R of κ of tool cutting edge angle of cutting tool, make 0 ° of ＝ of α of the horn after here cutting tool, the cutting tool when bringing about treatment thereby wears away acuteness, because this needs,undertake modification to form of blade of here cutting tool. According to normally method, can slant afore-mentioned cutting blade curves upcountry buy an angle, make the appreciably of tool cutting edge angle of here increases. Use hypostatic feature to build Extrude of → of Cut of command Solid → as before, underside of choice cutting tool is plot plane, scale goes out revise curve of blade of the following cutting, use it to cut spare part. Can use this kind of method to make the part of swallow end tenon of figuration lathe tool likewise, the three-dimensional and hypostatic model with figuration ultimate lathe tool is shown 5 times like the graph. Graph the scale of cut contrast figure of 3 figuration lathe tool is in the three-dimensional and hypostatic model of 5 figuration lathe tool after design of three-dimensional and hypostatic model is finished, with respect to the project that can use Pro/ENGINEER the graph makes a function finish 2 dimension project to pursue. Between the project attempt of Pro/ENGINEER and part drawing mutual correlation, after three-dimensional part drawing is revised, attempt of 2 dimension project can be changed automatically, this is one of advantages that use Pro/ENGINEER designs. The making method that 2 dimension project pursues can consult concerned book, here introduces in detail no longer. Pursue in Pro/ENGINEER project the system when tagging is default dimension is according to its three-dimensional substance gets, for the exact size of the spare parts, when because this is in,dimension is tagged, should accept default measure value. Additional, OK still adjust dimension precision according to machining the need of precision. After deciding proper design and scale, the view that chooses need undertakes umbriferous, still should make view of a section plane besides, in order to tags dimension. By meanwhile the F-g curve on cutting blade is hyperbola (see a picture 4) , with be differred completely by curve of outline of treatment spare parts, according to normally method should section tags dimension. Pursue medium in the project, use Edge command of use Tools → chooses the curve that should tag, reuse Divide command breaks up the curve into a certain number of paragraph, tag the measure that gives each a little bit next can. Because Divide command is a basis,arc length breaks up a curve, such making tag the part with the dot is concentrated and small curvature greatly to tag a dot partly in curvilinear curvature few and far between, be helpful for machining the treatment precision that figuration lathe tool raises in the method in the tradition. If the graph is shown 6 times,the form of cut of figuration lathe tool that scale completes pursues. Graph form of cut of 6 figuration lathe tool pursues the profile of the lathe tool of figuration of treatment arris form of profile of 4 figuration lathe tool is the cut form picture that gets is like a graph be showinged 6 times through computation or plot and data value normally, make cutting tool model next, undertake according to example cutting is machined, of the methodological take shape that has precision work on grinding machine of optical curve tool finally. Method of this kind of treatment is put in a lot of malpractice, and still get the limitation of plant equipment condition. At present the gains ground to be in a factory with machine tool of cut of numerical control line wide application of CAD/CAM technology, the treatment that gives figuration lathe tool is made provided quicker means. After use Pro/ENGINEER finishs 3 hypostatic model of figuration lathe tool, can create the numerical control program that is used at machine tool of cut of numerical control line directly, control machine tool has the treatment of cutting tool profile, simplified greatly so the production of cutting tool. Here no longer give uncecessary details. Use Pro/ENGINEER of 5 last words can simplify the design of figuration lathe tool, reduce the hyperbola error of cutting tool, raise the production precision of figuration lathe tool, the finish machining that makes figuration cutting tool is used at the spare parts becomes a possibility. CAD/CAM technology is the development direction of manufacturing industry, a lot of software that produce subsequently brought advantage to machine and be made of the spare parts. To the spare parts that be designed hard before and machines, can use new method and new technology completely nowadays to undertake designing production, can simplify not only so design method, shorten the design is periodic, and the manufacturing efficiency that can improve a spare parts to process precision and business.
