| In recent years,the modern manufacturing and numerical control technology is gradually developing,is now almost universal access to the three axes linkage numerical control processing technology.But the traditional three axis NC machining can’t solve some complex parts.This topic research the ellipsoid parts,impeller shaft and blade part is a typical use of multi-axis linkage NC machining technology.Therefore,according to the current actual situation,hard machining process,from material,clamping and cutting tools,processing technology,such as comparative analysis in detail.First of all,these parts must be part drawing process is analyzed on the basis of sufficient structural analysis on the process,can be more specific to determine the technical requirements,to choose more appropriate processing method,and to formulate a reasonable technological process,final implementation process,this way can the unity between efficiency,productivity,and quality fully reflected.Second,according to the related principle of NURBS curve,established the mathematical model of the NURBS curve interpolation method,and implements the dynamic variable step adaptive interpolation method,not only meet the demand of the machine tool error,but also to maximize the metal parts of feed speed interpolation processing,eventually greatly optimize the interpolation speed and accuracy,makes the processing efficiency and quality have been greatly ascend.Finally,according to build complex parts interpolation calculation,the mathematical model with the method of manual programming and automatic programming software to verify the algorithm,so as to verify the feasibility of the algorithm.The parts processing,although only a fraction of them,but whether high efficient and high quality to ellipsoid parts processing,will embody the processing technology of high and low.We for ellipsoid parts CNC processing technology is studied,and comprehensive in the numerical control processing technology has improved. |
