The Xin Liang of small milling CimatronE 7 is nodded

1mm) the curved surface precision that can acquire very little curved surface common difference and high quality, current NC software cannot achieve this precision. Small milling besides facing tiny part, still can undertake to the petty geometry feature of groovy large perhaps mould tall nicety is machined. Small milling can machine a precision to be as high as 5 micron above, hardness is more than the spare parts of 45 HRC, curved surface quality is achieved 0.

2 micron or smaller, the ply of fine muscle spare parts is small to 0.

5 micron or smaller. Small milling needs the software of high accuracy to try to support, computational common difference is little at be equal to 0.

1 micron, the requirement of likewise small milling to machine tool and cutting tool is quite strict also: Cutting tool diameter is small to scale of appearance of 100 micron, cutting tool (length / diameter) be as high as 10 to arrive 100, rotate speed of machine tool main shaft asks 150, 000 PRM or taller. Small milling basically is used in need to make the special trade of dinky tall nice spare parts, for example biology - the treatment of the miniature mould of medical treatment equipment, optical, microelectronics and tiny and plastic products and tiny metal spare parts. 2. Cimatron company releases the first NC software that accords with small milling: The admiral that Cimatron company released in September 2005 is produced implement E7, it is the first accords with small milling process designing commercialize NC software. Cimatron E offerred unique algorithm and special treatment strategy, traditional NC software place cannot realize these. The feature of this solution model includes: Treatment of the model of inferior quality curved surface that high accuracy, small fair poor treatment, efficient processing guides, direct curved surface and 3 axes the cutting tool method of 5 axes, satisfy and surpassed the demand that miniature cutting tool machines. The small milling of Cimatron E is the achievement of the project of small milling research that Cimatron participates in, this project falls in the support of Europe community by Germany inferior the institute of Fraunhofer product technology of treasure (IPT) leader, its assemble the world's banner mould makes a supplier, passed structure of complex high accuracy 3D to undertake test and verify to the production process of mould of tall accurate inject. Small system technology had stridden one stride to effective treatment from scientific research, the say of chief engineer Thomas Bergs of IPT: We are very glad see the gain that studies a project as European small milling, cimatron had realized special small milling function in its new version. 3. The application of process designing of CimatronE small milling reachs a characteristic: Below the NC module that enters CimatronE, build cutting tool way, tick off next choose Micro Milling option to be able to enter environment of small milling process designing, following plan institute are shown. The small milling of Cimatron supports 3 axes to arrive the cutting tool method of 5 axes, the kernel technology of ACIS offerred the in-house precision that is as high as 1nm, provided technical safeguard for small milling. Cimatron is seamed through notting have shrink put computational environment will raise precision, in computational environment according to enlarge have consideration, any pair of inputs or output model, view, emulate, code of NC report, G won't from generation any influences. The small milling technology of Cimatron remains truely through identifying miniature semifinished product, have the strategy such as mill of a horn of thick, 2 a thick, finish machining, Qing Dynasty like be the same as common process designing, streamline and cycloidal treatment, assure the efficient safety of cutter track contrail. 5 axes dip satisfies the short awl that needs 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 small milling, cimatron can use the strategy of a variety of high speed milling, for example: Be based on to take semifinished product from circle of ministry of horn of computation, method horn joins, finish machining of 0 jackknife cycloid, S mixes even the knife the knife below helix, get used to Z layer finish machining and streamline treatment to wait oneself. Such achieving reduce handling time, reduce the effect that cutting tool wears away and destroys. To make sure the treatment of high accuracy asks, need to have the mathematical model of high quality surely, the mass of product data model that if guide,joins is bad, a few small hole or person aperture is sure to affect real treatment quality, because of location, repair must have before CAM is operated. The Cimatron E that has CADCAM unifinication offerred hypostatic in machining an environment curved surface to mix formative function, this kind " to make design " the function is very convenient use repair geometry model, oversew the curved surface of all sorts of damaged into close hypostatic model, satisfied the precision requirement of small milling. 4. Small milling uses case: The following spare parts is the treatment example that rotor of a miniature notes model model pitch, the least circle horn of the model is 150 micron, 53 HRc of mould material hardness, milling machine tool is Kern, cutting tool Zuo uses Magafor. The treatment strategy that uses to finish machining place from rough machining, cutting tool and treatment parameter express place to show as follows: Machine the mould milling precision that go out finally<5um, curved surface surface roughness <0.

2umRa, following plan institute are shown. 5. Summary: Current and many product relies on pair of small systems establish, spare parts and child constructional demand is bigger and bigger, generate the demand of pair of tiny moulds subsequently, and these challenges that will make maker place be faced with again, huge success is scored on the market that because this researchs the forward position technology of small milling,is sure to grow in high speed.
