Develop increasingly in mould technology today, beg a project to be able to shorten instead design and make cycle of the mould, it is the strong tool that helps an architect realize collateral project to wait for contemporary design technology, received wider and wider application consequently. Applicable is in by foregone appearance request mould antrum appearance instead, what already had a pattern is duplicate and of attaint mould reductive wait for a respect. Beg a project to basically have technology of two respects key instead: It is objective appearance exterior data collects a technology; 2 it is curved surface reframes technology. The article basically uses PC-DMIS to measure software to combine software of CopyCAD converse engineering to realize fast curved surface to reframe. The 3 coordinate with inchoate introduction of software of software introduction PC-DMIS are measured machine can output coordinate to nod only. And can fasten next jobs in machine coordinate only. When be being measured so, need to search artificially first workpiece, mix the datum line of workpiece namely measure the make level of reference axis line of machine. The invention of the computer and application introduce digitlization technology survey engine system, was born from now on 3 coordinate measure software. PC-DMIS is based on 3 coordinate to measure namely of machine measure software, have: Geometry is measured, a variety of evaluation of public errand of new feature construction, behavior, scanning, off line or online generate a spare parts to detect program, imitate measures a process, off line is corrected measure program mistake, reduce the loss that the collision in measuring a process causes. Of implementation and CAD system software without seam join, read the CAD model data that takes work directly, decrease turn interpret error, raise process designing precision, shorten the process designing time, super report that offers interactive form. Pass VB interface, the user can design his program at will on PC-DMIS platform, finish special spare parts to measure with data analysis and evaluation. Delcam CopyCAD of introduction of Delcam CopyCAD software is the software of converse project system with the powerful function that manufactures by British Delcam company, it but from three-dimensional CAD model already produced in some component or actual model, this software provided a kind of integrated tool that can produce CAD appearance from digitlization data, accept 3 coordinate to measure machine, flaw-detecting apparatus and the data that laser scanner measures, simple and easy user interface makes the user masters its function and operation inside the shortest time. CopyCAD user can compile digitlization data quickly, can make high quality, complex appearance. This software can control the option of exterior border completely, form the flowing, many face piece curved surface that accords with formulary public errand automatically, still can assure photograph adjacent surface between tangent successional. Graph 1 be measure the data of machine to guide with 3 coordinate guide, the measurement with more real original report data. CopyCAD has friendly input to output interface, the data nodding the cloud that backs a variety of formats is read in. The example CAD that converse applying is begged instead is to pass scanning to nod the cloud (if Point Cloud) pursues 3 are shown, generate digital-to-analogue of CAD curved surface directly. The CopyCAD appropriative that passes Delcam company is converse engineering software, rebuild digital-to-analogue and revise make brand-new product. Nod the collection of cloud data: PC-DMIS software can realize editor window and graphical window to coexist to metrical element, the pattern that shows with three-dimensional graph shows an element. When having relevant computation and element of the choice in analysing a process, can choose a figure intuitionisticly from graphical window, improved work efficiency, if the graph shows 2 times: The user is OK and custom-built the graphical report of need, measuring a result to go up directly, scale graph. Will measure the information such as data and theoretical value and error to be tagged directly at the same time go up in the graph, can choose view way freely, with the most reasonable umbriferous square all along expression measures an outcome, absolved measure data aftertreatment to work. Measure must rise with modelling union consideration, the data that so that make,measures is nodded can the contented modelling need of utmost. The basis wants the part of scanning, choose to scan one-sidedly in PC-DMIS software, choose scanning strategy, install corresponding dialog box to found next: The speed when scanning puts 2 division, step pitch 0. 5mm, apply UV one-way scanning. If the graph shows 3 times: Nod the input of cloud data. CopyCAD offerred data of use dot cloud to establish the exact measure that trigonometry model place needs, and offer guide mode, can raise processing rate, reduced the menu function that need chooses, and under cover makes multiprocessing function below each measure. The tremendous to such amounts data that nod the cloud has capacity of efficient operation, editor. Concrete step shows 4 times like the graph: Trigonometry model generates the last pace of oriented dialog box to also can become the operation that data deletes, optimize below the premise that assures curved surface quality reduce point of disperse of the amount that nod the cloud, purify, assure the accuracy of triangular data. The geometrical construction that because wait for,measures a model to differ at the same time and use different device, achieve different measurement purpose, decided those who measure process and measurement technique is different, copyCAD converse software has the capacity that handles in the light of these different classification. The data in this exemple is contact measures a head, choose " contact " the diameter measuring a head that when CopyCAD inquiry digitlizes data, uses is the actual diameter that measure a head, use pair of data to undertake slanting buy, in order to get more true face. Guide is generated in trigonometry model in, the strategy of the use method that appoints scanning, scanning, most decimal according to changing row spacing to wait option measures software PC-DMIS with 3 coordinate organic union rises, truer reflected metrical primitive data. Generate guide to undertake to nodding cloud data trigonometry is changed through trigonometry model, a new model was built in CopyCAD browser, the name has a prefix is Tri_ , make clear had undertaken trigonometry is changed, if pursue,5 are shown. Trigonometry model can turn in PowerMILL to undertake curved surface turns an operation machine and do not needing directly. When PowerMILL undertakes machining to generated trigonometry model, can accurate become cutting tool way according to trigonometry model a future life. The compose of the curved surface in CopyCAD software builds: Curved surface is founded to a variety of methods will come true in CopyCAD, the user can choose suitable method according to the actual state of the model. The method that curved surface establishs divides roughly for: 1, through quadrilateral the law will found curved surface (this method will be strict become) of UV curved surface according to trigonometry model a future life; 2, extract diagnostic curve through the triangle, in turning diagnostic curve into PowerSHAPE, undertake to direct modelling; 3, locate directly through PowerSHAPE the body element feature of a few standards, leave out by measure, the error that produces in converse process. CopyCAD and PowerSHAPE are the product that Delcam company is based on research and development of Windows kernel place, on the expression of compatibility can says perfect. Well-known, the work of converse project is simple will come true through converse software is more difficult, the partial section of the model can pass the curve in PowerSHAPE to perhaps locate standard system always is finished directly, through to, converse photograph union gave converse engineering work to bring huge advantage, the memory with frequent leave out and read take, those who replace is a pushbutton only, needing one key switch only to converse working environment, true implementation is not being had conversely seam compositive. Traditional quadrilateral the law founds curved surface also is very handy in CopyCAD, need 4 end points of model of ordinal choice curved surface only, immediately of curved surface model arises. To attrib border and complex area, ctrl key can be pressed when choosing end points, OK and aleatoric accretion the reference point among end points, with the better attrib border outline that controls curved surface. If pursue,6 are shown. Better to still having at this model the method that establishs curved surface: Extract diagnostic curve through the triangle namely; To this model analysis, discovering the curved surface that carry a department is become by circumgyrate of a curve, we need to extract diagnostic curve in converse project only, turn to producing circumgyrate curved surface to the middle of the environment, so OK and fast acquisition carries the curved surface model of the ministry, reduce operation measure, simplify unit process of cargo bandling. If pursue 7, the graph shows 8 times: Curved surface is founded after finishing, the curved surface that we need to be founded to place undertakes the error is analysed, examine curved surface is eligible, copyCAD offerred intuitionistic error ribbon to analyse a function, can the error value that set allows, control the color range that the error shows thereby. If pursue,9 are shown. While the error is analysed, copyCAD still offerred exact error to be worth, such facilitating users are accurate control error cost. CNC Milling
