Research On The Influence Rule Of Dry Milling On Machining Environment Based On Groove Optimization

With the development of green manufacturing technologies and increasedattention to the environmental protection, dry cutting is the effective way toeliminate the pollution of the cutting fluids, reduce product cost, and realize cleanproduction. However, in dry milling, cutting noise, dust and chips flying haveeffect on the machining environment, and cause damage to the operator. Drycutting must be reasonable selection of cutting tool material and the toolparameters. The milling cutter performance greatly depends on the material of theinsert and groove. Application of complex three-dimension(3D) groove millinginsert is increasingly broad, but, until now, there has very little research on theinfluence of different groove inserts by dry milling on machining environment.Therefore, in order to improve machining environmental quality in dry millingprocess of different groove, aim at heavy cutting to discuss the effect principle ofdifferent groove milling inserts by dry milling on the machining environment, soto provide a theoretical and experimental basis for the deep research onimproving the machining environment of different groove milling inserts by drymilling and groove development technology.First of all, the different groove milling insert cutting noise experiment iscarried out, and the collected data are analyzed and processed. And thedistribution of cutting parameters and cutter groove type on the noise emitted bymilling is further studied. By adopting the method of stepwise regression analysis,the milling noise model is established. Cutter-workpiece system geometric modeland finite element model are established, analysis cutter-workpiece system modaland calculation vibration response based on the modal, prediction the cutter-workpiece system radiation noise through the direct boundary elementmethod, so to provide a certain basis for improvement the workshop environmentand optimization groove of the milling insert.Secondly, different groove insert milling dust experiment is performed. Testdata are handed and analyzed, and the influence rules of cutting parameters, toolangles, cutting deformation on the dust produced during milling are analyzed.Dust distribution theory model is given preliminarily, and dust distributioncharacteristics are studied, contour map which can intuitively reflect thedistribution of dust concentration is get. Dust diffusion conditions are studiedfrom the perspective of energy transformation.Again, different groove milling chip splash experiment is completed.Through the analysis of test data, it is concluded that the influence of cuttingparameters on chip flying. Chip theoretical model is given in the space splashwith different sports, but also points out that the influence of tool rake Angle onchip flow.Finally, on the basis of research on the law of noise, dust, chips produced inthe milling process using different groove milling inserts, noise distribution filed,dust dispersion field, chip splash field during the milling are fuzzy evaluated,using the theory of comprehensive evaluation which lay to a certain foundation oftheory and practice for the groove technology development of further research.
