Research On Nc Forming Grinding Thechnology Of Spiral Rotor

The subject of the text is the form grinding processing technology on the complexsurface. The text focuses on the study of the spiral curved surface on spiral rotor, whoseaccuracy of the processed surface is directly related to the working accuracy and efficiencyof the working device.Currently，the major manner of the curved surface processing on spiral rotor ismilling，whose efficiency, however, is not good enough，so is the accuracy. Therefore, tosearch for a new processing method on how to improve to process the spiral rotor surfaceefficiently and accurately has been a focused subject.The text, which is based on the meshing movements between the form grindingwheels and workpieces in form grinding process, works out the outlines of the grindingwheels with mathematics, also, analyses the solutions of discrete point derivative and theoptions of setting angle. In addition, according to the profile of the grinding wheel acquiredby example calculation in this method, I use the software to do the simulation analysis.Based on the introduction of the form grinding technology, combined with thecharacteristics, the text focuses on the superiority of the CNC grinding technology in thespiral surface processing.This paper, molding cutter machining helical surface toothed computing researchengagement theory and mathematical methods to calculate the form grinding wheel profileof use, according to the basic parameters of the spiral rotor end face type line of discretepoints and helical rotor lead, and in such a calculation process of the preparation of aspiral rotor end face type line of discrete points, including input to display easy molding ofthe rotor end line point coordinates and sand contour-shaped point coordinates grindingsand contour calculation software, combined with the machine control system so thecomputer as a terminal with CNC system closely integrated effectively improve processingefficiency and accuracy. According to the current domestic situation that the form grinding technology onspiral surface has not been applied widely,the text has a profound practicalsignificance,which provides a basis for the development of the CNC grinding technologyon spiral rotor, also,offers a new direction for the study of processing equipments oncomplex curved surface.
