How does the factory make good HSM preparation? Plan of Minco of factory of a of Ohio Dayton city large mould installs the first to agree with technically later on this year the machine tool of particularly high main shaft rate and high speed feed, still took all necessary step meanwhile, so that transfer smoothly,arrive HSM. This factory is in in perfect order the ground begins " culture " and orgnaization of two respects change, be HSM come on stage preparative arena. The job of a few preparation that Minco has for HSM place is very rich innovation spirit, among them one is assign the " of " research and development that one person notices cutting cutting tool and its technology centrally, another example is to use existing equipment start off before the others to use HSM technology (the shallow cutting) that undertakes small contrail interval with small cutting tool. The member that design, programmer and machine tool operator are in savour HSM, experience among them a few redound and challenge. Want high-powered machine tool to reach the designated position only, these experience can produce very precious value. Still have, the certain bottleneck that HSM may produce gets exposed beforehand, through new DNC software, computer the network upgrades and new production attempers system and solve. In retain synchronous respect with newest cutting technology, minco is having good outstanding achievement, be in for instance several years before it most bought milling machine of high speed black lead first, in order to simplify the manufacturing technology of electrode. In fact, the to the most new-style machining center and electric spark equipment successive investment inside a few years and the adept government that produce a material to these, make Minco becomes the die manufacturer of large quantities of prominent clients and favour of car product maker. However Minco won't satisfy the current situation, vice-president of no less than holds place of general manager Joe Kavalauskas concurrently to say, "Cannot anchor is on the technology yesterday, although they are very useful today; Must search next outlets. "He and John Levering of Minco technology manager conclude, turning to HSM is next act, but also be arduous one pace, because HSM is met,make many sided from what factory of the influence on the foundation runs. "We feel need has a person to be in charge of an organization technically, all thing method that must learn us and had had are changed, go up again for high speed cutting and other development a step makes good preparation. "Then, it is about two years ago the position that they created " of director of " research and development, amount to long Jon Allen of more than 10 years to hold a post by ministry of responsible Minco program. His duty includes: The special subject meeting that study HSM and holds through attending supplier of machine tool manufactory, tool and college and groom course and gather the information that concerns optimal experience and course of action. Undertake in the workshop experimental cutting is mixed set an example, be familiar with the cutting tool of different form and bit plated film in order to help the validity of technology of process designing of test and verify. The cutting data with the commonly used person that through the assemble programmer etc is used, formula gains HSM knowledge with form. The member that programmer, machine is held to machine person, design inside the factory and tool room administrator grooms class. The evaluation is recommended conduce to the new software that improves manufacturing technology. Programmer ready-made transfers to HSM, sex of may richer to CNC programmer challenge, mr Allen holds the position of the old experience of CNC programmer in Minco according to him, branch of hep process designing before the cutting tool with bigger diameter of choice of overweight of working way side and use multiple process, until process semifinished product to final position. Such means manages from what do not open operator or intervene and need changes a knife for many times. And they are choosing lesser cutting tool in study nowadays, make through comparing little process semifinished product reachs basic figure. The semifinished product that wants cutting to place of these small cutting tool tries to be controlled carefully, can raise feed rate, and reduce the working burden that operator is staring at a machine tool to operate. Return collection additionally criterion of a new-style process designing, go to the lavatory to catch up with and got used to this one process to offer. Content includes commonly used cutting strategy (the optimal method that for instance cutting tool is contacted and breaks away from workpiece) , the computational formula of crucial cutting parameter and use feed rate and main shaft rotate speed are recommended below material of different cutting tool, different workpiece. Write these standard into "HSM programming manual " , make programmer learn each other and be beneficial to the consistency that assures program of work of one by one. The consistency of process designing conduces to machine treatment person as HSM transfer, know to should expect what is mixed what must notice. Graph: Minco uses HSM technology at the standard machining center such as Makino FNC 120, basic skill of this kind of " trains " to be engaged in HSM truly to machine treatment person and programmer very helpful. The software that builds cutting tool way has upgraded, minco company uses Unigraphics and WorkNC software now. the design program with respect to cutting tool method, unigraphics lay particular stress on is mixed at fine mould detail other is complex the process designing of geometrical graph, below these circumstances, need control and the exercise that adjust cutting tool. For instance this software includes feed and the option that cancel a knife. WorkNC more agree with the spare parts with detail particularly much change, because this software has state of surveillant mental allowance, use mental allowance model to create cutting tool method and the function that build data of cutting tool method quickly. Technology of new process designing makes the necessity of method of school nucleus cutting tool more clearly, minco uses the software of Vericut desired result of CGTech company. Program of moving desired result can increase process designing time, but can ensure confidence of machine treatment person runs a program dye-in-the-woodly, meanwhile keep an eye on is other the task. Method of desired result cutting tool is the job of get twice the result with half the effort, can improve the efficiency that manufactures a workshop. In addition return those who consider cutting tool way to optimize, the sheet that produces to Minco place nevertheless for workpiece, optimized value appears finite. Although actual beneficial result uses HSM technology to groovy CNC machine tool, the effect is far however more than training jackarooes, bring a lot of significant results to Minco however, such as: Handling time shortened: Right cutting tool way allows to raise feed rate as far as possible. Exterior luminosity improved: Reduced manual polish time. EDM operation decreased: A lot of detail that use electric spark treatment before are OK now milling. Hard processing reduced the temper by dipping in water that the exterior place after cutting needs. Cutting tool life lengthened: Cutting condition consistency and the improvement that cut bits force stability and use shallow cutting, make cutting tool life is able to lengthen, the effect plays in certain circumstance particularly remarkable. Full automatic change (or unmanned in charge of) the cutting that intervenes artificially rarely with need increased. Although HSM just shows horizon in Minco,HSM foreground is looked into, minco has been in look into new technology. According to the view of Levering, the target of this company is the model that introduces software of 3D hypostatic model to build whole pattern workmanship. This kind of model can include cutting method not only, and the function that the outfit recipe method that can include all parts and finished product mould provide for the client, still emulate through imitate test and school nucleus get below " of " virtual reality, produce better mould design thereby, also produce what coordinate highly to create strategy. "After the technology that uses HSM and so on, want managing cutting time will be more and more difficult, about what improve efficiency research will change other aspect. "Mr Levering says, can so say, the key of research changed, but without the end. Application of horniness plated film analyses cutting tool of plated film cutting to comprise by two main essential factor: Matrix and plated film. To build technology of successful high speed cutting, the combination that chooses optimal matrix, plated film to the data that awaits cutting is a decisive preparative move. In high speed cutting, reduce oscillatory source or cutting tool brace up quiver the source is a main consideration factor, this is why operation of high speed cutting recommends the matrix with use better tigidity normally. When choosing base material, cobaltic content is lower (6 ～ 8 ％ ) , the horniness plated film of micron granuality is a very good start. The 2nd cutting tool element that deserves a consideration is: Most agree with what is the plated film that high speed processes? Important is plated film should assume double function, avoid to bit matrix gives out heat and be reduced namely edge and cut the attrition between bits. The major quantity of heat of high speed cutting is cut bits is carried, because this plated film machines the effect that has to be made namely to high speed,cut bits to eliminate as soon as possible, lest conduct quantity of heat to cutting tool. Reducing the coefficient of friction between workpiece material and cutting tool plated film is the target that discharges bits quickly, some plated film (if TiAIN) contains lubricant part, it is to decrease cut bits optimal to cutting tool tatty plated film. How does treatment choose correct plated film cutting tool for high speed? Next watches can help you match commonly used cutting tool plated film and general use. Black lead of TiN of plated film utility and hardness of aluminous TiCN the steel under 42 HRC (the steel that exterior cutting speed does not exceed 42 HRC of prep above of hardness of 800sfm) TiAIN (exterior cutting speed is more than 800sfm) ZrTiN aluminium, diamond, stone CNC Milling
