An Array Of Micro-cylindrical Plunge Cutter Design And Processing Technology

An array of micro-cylindrical parts such as a spinning plate electrodes, medical biomicroneedles,damping plate, optical storage, light guide, micro chemical chips have parts as atypical array of tiny structures，which are widely used in micro-mechanical, high-tech medicalequipment, nuclear power plants, electronics and other fields. The array of micro cylindricalstructure forming part mainly by traditional machining, discharge, and other micro-pressingmethod, but the low prevalence of efficiency, quality of instability, complex process and otherissues. In view of the domestic manufacturers need an array of micro-machining cylindricalinnovation process，this article will conduct research on an array of micro milling insert cylinder.Firstly, This paper describes the processing method of the domestic and foreign researchstatus tiny structures and plunge milling；Analysts believe that the plunging technology is aneffective means to create an array of micro-column structure. For this reason，the design of thecorresponding cutter-wings plug cutter.Secondly, the wings plug cutter geometry，the cutting insert milling parameters to meet therequirements in the cutting process:(1) high cutting efficiency;(2) high precision;(3) symmetry.On this basis，established parametric model of the tool，and the use of UG expressions in thecontrol parameters of the tool, in order to draw and modify faster cutter model.One more time, According wings plug cutter model on trial cutter grinder, grinding processto explore, test the plug cutter precision，Experiments conducted at machining center cuttingforce (DMG), the cutting force model and the establishment, By UG Advanced simulationmodule，analysis of centrifugal force and cutting force and deformation effects on the tool.Finally, under the premise of cutting force of the tool does not affect the shape of theworkpiece deformation accuracy, plunge milling micro-array analysis of the efficiency andaccuracy of the cylinder, thereby producing spinnerets electrode, damping plate and otherproducts, depth of field in the ultra microscope and NANOVEA3D surface topography andsurface shape precision instrument detects tiny cylindrical array roughness. Summary andprospects in the wings plug cutter plunging cylindrical part of the follow-up micro-array content.
