Enter in engine, in the treatment unit process of cargo bandling of vent, the PowerShape design software of Delcam company and PowerMill treatment software helped manufacturer of component of this high-powered racing bicycle achieve mix accurately efficient treatment target. One of relatively difficult operations that manufacturer of component of high-powered racing bicycle comes up against are to enter, the treatment of vent, namely engine air cylinder processes an operation into the machine of gas mouth and vent. The geometrical form of these mouths that take energy of life and vent is complex, contain certain curve and vertebra to spend, its interior is close to hard, and its surface is bright and clean degree of demand is higher. Accordingly, execute this special application order effectively, involve the special treatment facilities of certain type normally, what include to be able to achieve these mouths that take energy of life and vent among them is certain the sucker that nears area hard cutting tool and machine tool of treatment of 5 axes linkage. However, the software tool that before still beginning what have likewise important sense to machining efficiency to be machined actually, uses, the software that is used at designing gas mouth and vent namely and the software that provide method process designing with Yu Dao. For this, lid of MBE air cylinder and manifold production company rely on the PowerShape that comes from Delcam company to design software and PowerMill machine program to undertake machining production. The presiding process designing of this company member Mr Mark Olson says, of the engine of powerful surface treatment of PowerShape software and PowerMill software enter, vent is automatic machine program is to get place to need precision and surface bright and clean spent key, can hold inferior treatment cycle time at the same time, avoid to add man-hour happening collision and other issue. "Ever had used a lot of programs in my professional career, but this is a the smallest program that I had used. " he says. MBE company founds 1997, found by Mr Matt Bieneman, be located in American north to block the center of kingdom of motorcycle race of city of Mooresville of Luo Laina city. Mr Bienenman is close since this group a batch of elite chose in course of study, established an expert team, and with same way, choose and buy specific treatment facilities and software. The credit of MBE company builds the alternative base in its quality and project level over, the cycle racing team that makes this workshop can precede from whole United States, Australia and Canadian first selection thereby and engine manufacturer. Its client includes to come from mud racing bicycle and tensile contest and tractor and lorry pulling force to surpass cycle racing team of the competitor. Enter, the design that the first pace of vent treatment craft is manifold, this company uses handmade means to undertake designing. Once this design is satisfactory, the company can is opposite into, the place that with etc any need machine has vent, studio digitlization processing, in the PowerShape software that mixes data input molding process to the CAD of Delcam company next. Over, process designing member the face that uses this software machines engine, perfect its to design further. "I am too other without discovery still the figure that any software can cut the ground to need completely according to my place truly, undertake to exterior data so effective operate. " Mr Olson says. After there are the mouth that take energy of life and vent model to be perfected further above engine air cylinder, process designing member this design move arrives in PowerMill software, this software can be used at undertaking entering on hypostatic material already, the immediate treatment of vent, also can use at the finish machining of engine cast. Mr Olson says, the transparent interface between system of these two software, can make its undertake fast cutting is machined easily, and appearance of a geometry stickup arrive over another geometry appearance, need not undertake normally input and output operation. To MBE company, the main benefit of PowerMill software depends on his having optimize treatment sequential ability. Mr Olson explanation says, to entering, the treatment of vent, process designing member adopt 3 old strategies: Treatment of 3 axes cutting, successive 5 axes cutting is machined and locate 5 axes cutting is machined (also call treatment of 3 + 2, but locate treatment of 5 axes cutting is different from successive treatment of 5 axes cutting, in a 3 axes in machine program process, former cutting tool passes two runner shaft coming back with certain angle locking. ) to major machine tool, 3 axes and locate machine program often has 5 axes bigger tigidity, it can reduce vibration, can undertake with higher rate more accurate cutting is machined. In view of this one reason, as long as likely, job shops likes to use these option. However, engine is entered, the certain area of vent needs to use successive 5 axes treatment. Mr Olson says, powerMill software will be accessible to 3 axes treatment the craft between area and the area that need 5 axes treatment undertakes differentiating automatically. This aux will be able to is machined through 3 axes quite and locate 5 axes process an operation, ensure excision as far as possible much material, just use in necessary place successive the method that 5 axes cutting machines. Accordingly, the workshop can shorten machine periodic time, can satisfy the surface again at the same time bright and clean spent requirement. To rough machining cutting, should enter, the machines order to use helix to move means of vent. And to finish machining, operator can choose a kind of interpose the treatment method between screw type or inverse type. Method of screw type treatment is met generation and into, the pointed horn with vent perpendicular air current, what increase air current thereby is queasy. As contrary as this, the way that the pointed part that uses inverse type technology to machine a generation and air current run is parallel. This can quicken gas mixture through. Mr Olson says: "PowerMill software has very powerful into, vent is automatic machine program, this is why one of main reasons that we buy it. " his complement says, the add function of PowerMill software gains high grade face for MBE company bright and clean spent process capability made contribution, this is entered to engine, the effect with the particularly main move since the function of vent. "This can make edge maintains with into, the contact of vent, make its are in as opposite as point of a knife position. Because use edge cutting, the appearance with can make you are obtained better is bright and clean degree. " in addition, he returns an explanation to say, of this software into, vent machines strategy to be opposite each a little bit distributing have very large control capacity. Increase the amount that cutting tool method nods, can make treatment more stable, reduce vibration, make the negative charge of cutting tool more uniform. Besides improve the appearance bright and clean degree beyond, such doing wear away that what still can reduce cutting tool. This software still can differentiate automatically CAD model, found thereby from into, any one aspect of the matter undertake vent the surface of treatment. The user can appoint the jackknife length between method of two cutting tool, transfer smoothly between two area in order to ensure. Finally, mr Olson explanation says, since since using PowerMill software, although this workshop is being handled ceaselessly all the time small to 0. The treatment clearance of 015in, but never had produced mutual interference or collision phenomenon. On one hand, this is in view of a such fact: Be in namely of cutting tool method in establishing a procedure, this software can " see " this model. In addition, this software can be together comprehensive groove and collision examination union, in order to ensure safety is machined. Still module of a test and verify can offer bigger assurance, ensure the program undertakes strictly operating according to the requirement of the workshop. "No matter how its form is complex, I can believe firmly, it can is opposite in first time into, vent undertakes correct cutting is machined. " Mr Olson is summed up. Besides very high exterior quality demand, engine is entered, the form of vent interior is more complex, this meeting brings a few issues to the clearance of cutting tool. Of PowerMill software enter, vent is automatic machine program, the operation between the area that can near through be being machined to 3 axes and the area that need 5 axes treatment undertakes differentiating, optimized treatment craft. The presiding process designing of MBE company member Mr Mark Olson says, the surface inside PowerShape software machines engine, simplified the unit process of cargo bandling of exterior data, make its are gone to by the input in the model before PowerMill software, optimized its design further.
