Polygonal Profile

On the basis of analyzing the structure characteristics of the Isometric Polygonal Profile (IPP) hole, equations of the track for grinding wheel center and the formula of calculating node coordinates according to equal-error linear approximation method are established and the determination method of grinding technology parameters value and problems to be attention at grinding process are discussed. Grinding experiments show that both processing precision and surface roughness can reach with the fit requirements of IPP connection according to these principles. It is available for reference that grinding complex non-circular column surface is ground by CNC machine tools.
