The last few years, make those who reach the field requirement such as accurate and imperceptible treatment as aerospace, mould increasingly extensive, technology of high speed cutting had received very great progress and application. High speed cutting has special demand to system of machine tool, control, clamping apparatus, knife not only, also ask CAM software optimizes strategy of cutting tool method at the same time, of speed of helix or circular arc feed, cutting mix continuously waiting without mutation and contrail of cutting tool of the horn that do not have a needle should be used as far as possible in all sorts of cutting tool courses, in order to assure cutting process mix smoothly fast. Cimatron E is the CAD/CAM comprehensive solution that industry pattern industry offers, offerred a variety of strategy in the light of high speed milling, include intelligence to open feed of thick, intelligence, and fabricating strategy. Additional, cimatron E still offerred helix feed, round horn to walk along rate of interpolation of join of knife, round horn, cycloidal treatment, NURBS, feed to optimize and carry cutting load constant wait for strategy. Be aimed at groovy product or mould, technology of current high speed milling had produced tremendous effect, but be aimed at giant spare parts and miniature spare parts, groovy high speed milling is helpless, and Cimatron software is aimed at giant spare parts and miniature spare parts and mould offerred strategy of brand-new high speed cutting -- insert mill and small milling. Cimatron is aimed at super- model the way that spare parts or mould offerred special high speed cutting -- insert mill. It is one of treatment methods with metallic the most effective cutting. To the curved surface of difficult treatment material treatment, grooving treatment and cutting tool are hanged extend the treatment with bigger length, the layer of the convention of treatment efficiency far outclass of the law that insert mill cuts milling way. Insert mill to be able to reduce workpiece to be out of shape the radial cutting force that reduces milling machine. Inserted mill to offer efficient treatment strategy for rough machining and finish machining. Rough machining can be used tall bear the weight of cutting tool undertakes milling like bore, although feed rate is again high, cutting tool also is axial gets power only. This kind of strategy is usable also will be aimed at perpendicular or adjacent vertical section has precision work. When the bovine bazoo knife that should use big diameter or roundlet part, come to usable and fewer cutter track to finish needs curved surface to machine. The rough machining of very deep to deepness housing also can use the means that inserts mill, when housing is very deep, need very long cutting tool, at this moment cutting tool tigidity is very poor, the cutting tool of cutting course cutting that presses convention is changeful form, and easy also generation is oscillatory, the influence machines quality and efficiency, use the orbit as it happens that inserts mill to be able to solve this one problem. Graph 1 graph 2 Cimatron E offerred a variety of optimizing to insert mill to machine cutter track strategy includes, applicable this can choose is side insert or be the center inserts mill, also can define insert mill the smallest deepness and direction, be aimed at the place of corner, cimatron still can define those who insert mill to include angle, thereby step pitch of self-correcting side direction, avoid cutting to force greatens suddenly in turning point and be damaged to machine tool generation. Small milling (Micro-milling) it is to machine a kind of small part and tall nice spare parts brand-new processing technique. Small milling uses very small cutting tool (the diameter is less than 0. 1mm) the curved surface precision that can acquire very little curved surface common difference and high quality, current NC software cannot achieve this precision. Achieve the CAD/CAM software of small milling level as the first, cimatron E7 offerred hypostatic in machining an environment curved surface to mix formative function, because of the mass of product data model that if guide,joins is bad, repair must have before CAM is operated. A few small hole or person aperture may bring about final treatment workpiece quality is low. Build a model to differ with simple substance, the mixture of Cimatron builds a model to have " to make design " the function uses repair geometry model, through confluence of all sorts of curved surface function aperture becomes entity. To obtain above to ask, small milling technology needs to achieve the following support: Scale of appearance of 100 μ M or smaller cutting tool, high speed cutting tool (L/D) 10 or be as high as 100, main shaft rotate speed is as high as 150, 000 R/min or taller, treatment public errand is amounted to 0.
1 μ M or smaller, mould material hardness arrives 53 HRC, the precision of miniature mould milling<Surface roughness of curved surface of 5 μ M <0.
2 μ M Ra. The flagship product E7 of the Cimatron company that just releases used hypostatic curved surface to mix the technology that build a model, technology of its ACIS kernel offerred the in-house precision that is as high as 1nm, provided technical safeguard for small milling. Cutting of applied high speed is passed in machining a process (HSC) strategy gains even and consistent cutter track, used knowledge of semifinished product remain to prevent a knife, leave with undertaking to miniature antrum thick. The discontinuous miniature curved surface of the generation in preventing to change knife course to reduce a risk, cimatron E offerred a variety of treatment strategy. What NC supports diagonal in strategy or the knife below helix assures cutting tool utmost is smooth and enter work continuously. Graph the small milling technology of 3 graphs 4 Cimatron remains truely through identifying miniature semifinished product and those who have same function thick, open thick, precision work 2 times small leave with cycloid thick wait for treatment strategy to make sure cutter track contrail is efficient and safe. 5 axes dip satisfies the short awl that needs very small diameter knife to have the treatment of the spare parts, and hardness is tall the material treatment that asks curved surface quality is high. To satisfy the requirement of high speed milling, cimatron used strategy of a variety of high speed milling for example: Finish machining of cycloid of join of horny ministry round role, 0 jackknife, S connects knife and snail screw off knife, get used to Z layer finish machining and streamline treatment oneself. Same Cimatron E supports batten to approach treatment and streamline milling, reduce handling time, reduce cutting tool wears away and destroy. Small milling is the future of high speed milling, perfectness the company of mould of tiny essence of life will have greater competition ability, cimatron E7 regards the first commercialized small milling as the product, led the development of high speed milling way.
