Above all, the design of centrifugal impeller data text guides in UG NX, make a point, according to designing blueprint to make at the same time hub is mixed the sectional line of round of lid. Graph data of 1 blade profile is nodded next round the corresponding dot on lid and hub face is connected point-blank, will form curved surface point-blank, unit process of cargo bandling is: Insert -- FreeFormFeature -- Through Curves. hub sectional line uses rotate shape make hub range unit process of cargo bandling is: Insert -- FormFeature -- Revolve pursues 2 impeller model 3, the alterable axis of the work out UG NX of numerical control program is machined (VARIABLE CONTOUR) geometrical element includes spare parts face, examination face and drive range. Face of the spare parts in the treatment of centrifugal impeller flow path is hub face, examination face is blade curved surface, drive face assists a face for flow path. Appear in three-dimensional visible software previously, the CNC Machining contrail of flow path is discontinuous knife orbit, and the precision of treatment is very low, outline spends the requirement that short of designs. And after centrifugal impeller flow path realizes clipper-built treatment, the streamline treatment of flow path accords with course of air current flow, make the treatment quality of the spare parts got better assurance thereby, function has better improvement. The clipper-built treatment knife to realize flow path orbit, cannot make drive range with whole hub face, and the drive range that needs to assist curved surface to do flow path to machine (see a picture 3) . Graph the reseau line Nextpage 3 of 3 drive face.
Of 1 drive face generate curved surface of will big small lamina to slant toward flow path a side respectively buy, slant the radius R that buy distance is milling cutter, insert -- Feature Operation -- Offset Face, get slanting next of buy curved surface and hub face cross a line, and in flow path go up what end asks to make a flow path is medium branch line, the curved surface of drive of two half part that uses these a few curves and boundary boundary line to be able to make flow path respectively (see a picture 3 in the two curved surface of blue and yellow) . 3.
2 knives of orbit after generating everything to prepare the job to finish, can weave knife orbit. The treatment range that certain good part needs here, interference examination face, drive face (vector of axis of Drive Method) cutting tool (the umbriferous vector of Tool Axis) and drive face. The vector that the crucial point here depends on deciding cutting tool axis namely of cutting tool swing vector. The treatment face of the spare parts chooses whole hub side, interference checks a face to choose the blade curved surface all round flow path, the auxiliary curved surface that the pace on drive face choice makes. The vector of cutting tool axis chooses interpolation way (Interpolate) , when cutting tool axis (after Tool Axis) chooses interpolation way, in drive face all round appear vector of two cutter shaft (4) seeing a picture. Generate a knife if orbit hind appears cutting tool and interference of blade curved surface, can click vector of interpolation of cutting tool axis, choice cutting tool interferes the cutter shaft vector of area, this vector becomes blue, click an editor (Edit) , through adjusting a knife vector will avert interference, the knife that generates finally if orbit pursues 5. Graph interface of treatment of 4 alterable axes pursues vectorgraph of interpolation of 5 cutter shaft contrail of 6 clipper-built cutting tool 3.
The postposition of software of UG NX of application of 3 postposition processing handles compose to build tool Post Builder to build the postposition of Hermel machine tool to handle, be as follows via handling the block format after: %L01 G71 * N1 G00 X+0.

The occurrence of 501 * N6745 G00 Z+200 * N6746 M09 * N6747 M05 * N999999 %L01 G71 * 4, conclusion as UG NX, the clipper-built treatment contrail of the centrifugal impeller flow path that has size blade becomes a possibility. Although still do not have automatic impeller flow path to machine a method in UG NX, but propose the way such as auxiliary curved surface through compose, can weave the numerical control program of complex part.
