Research on Position and Orientation Algorithm of Precision Helical Groove Grinding for End Mill Based on Standard Grinding Wheel
In order to improve the grinding accuracy of the helical groove structure parameters of the integral end mill,the calculation method of helical groove contour forming is improved,an improved algorithm for solving the grinding wheel position and orientation of end mill helical groove is proposed.Parametric modeling of the grinding wheel and the movement relationship in the helical groove grinding process is built.Use the analytical space envelope principle and the discrete method to calculate the contact relationship between the continuous and discontinuous points of the grinding wheel profile and the workpiece,obtain the complete contact line between the grinding wheel and the workpiece,and calculate the helical groove cross section profile.According to the geometric definition of the helical groove's rake angle,core thickness,and groove width parameters,the functional relationship respect to position and orientation of the grinding wheel is estab-lished.The grinding wheel position and orientation solving problem is transformed into a mathematical optimization prob-lem,and the intelligent algorithm is used to solve quickly.Through simulation experiments,the accuracy and adaptability of the algorithm are analyzed,and the effectiveness of the algorithm is verified.
