“…The profile connection is formed while the wheel hub and shaft are fitted by smooth non-cylinder surface, and which belongs to no-key connection and the isometric polygonal profile connection is one kind of no-key connection. Compared with the connections of key joint or spline joint, isometric polygonal profile connection has much more advantage in the technology and using as following [1,2]:…”

Because of the problem of key joint or spline joint, the isometric polygonal profile connection was put forward, and the mathematical model of isometric polygonal curve was analyzed in this paper. Based on the periodicity characteristics of equivalent effective stress and total displacement in the whole structure through preliminary analysis, 1/3 structure of isometric polygonal profile shaft and hub was adopted during geometry model being established. The shearing strength in isometric polygonal profile hub and shaft, the main stress in hub and the total strain in shaft were calculated and analyzed based FEM.

“…To take account of dimensional accuracy, surface roughness and processing efficiency requirements, in general, grinding can be taken as end procedure of machining work surface of IPP shaft or hole. However, because the forming movement of IPP is complex, it usually has need to be completed in the CNC machine tools, but CNC grinding machines which can be to meet the technological requirements of machining IPP are rare [1][2][3][4][5][6]. The problems of grinding IPP with CNC vertical machining center is discussed in combination with the structural characteristics of IPP in this paper.…”

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.

“…In 1990s, Germany's professor W.Beitz indicated, "The development of CNC numerical control grinding technology would give promise of paving the road for the further application of polygonal profile connection." In recent years, a successive attention of the study on high speed and high accuracy NC manufacturing technology of non-circular parts was attracted internationally [1,2,3]. The machining and application research on IPP in our country started fairly late.…”

In order to study the grinding technology of Isometric Polygonal Profile (IPP), NC grinding accessory of IPP is developed, which is driven by Program Logic Controller (PLC) and step-motors. On the basis of the principle of coordinate conversion and envelope curve, formative motions of IPP are discussed in detail. Because the relationship between the rotation of parts and synchronization motion in both x and y axes of coordinates frame is of the proportional transmission, and the synchronization motion is harmonic motion in both x and y axes of coordinates frame, the relationship of them is of the proportional transmission too, but the frequency of the synchronization motion is low and the displacement is small, so the eccentric mechanism is used in the grinding accessory. The grinding process of three axes linkage of IPP can be translated into process of two axes linkage between three coordinates on machine tools by means of combination of PLC and the eccentric mechanism. It has been found by grinding experiment that the NC grinding accessory is available used for grinding IPP and other polygonal profile.
