The Profile Error Compensatation Of Globoidal Indexing Cam And The Movement Simulation Based On Solidworks

This paper briefly deduces the profile equation of the globoidal indexing cam by the means of space mesh theory and method of rotating transform tensor,it also analysis the cause of the error of cam profile deeply and gets the resolvent to the problem: a new control method of the tool. Based on Solidfforks2000, the paper also completes the parameteric entity proplasm to the cam mechanism and give the machining and mesh simulation about it, such of them will become a beneficial probe to CAD/CAM. The main work are as follows:Firstly, in order to resolve the problem that the complex deduction of the globoidal indexing cam are difficult to understand for most of the engineers, this paper have deduced some design parameters about the cam by the use of some new methods , such as profile equation-, pressure angle . The paper also did some deep research works about mesh characteristic.Secondly, this paper mainly discuss the profile error about the globoidal indexing cam and the various affect factors during the machining process, and obtained a important conclusion , i. e. when tool error occurs,no matter what kind of compensation method are used , the error exist on the machined profile will not disappear. Based on it, the paper put forward a new control method of the tool, and this improves the manufacture precision greatly, and this also provides an economical and feasible referenced solution for the grinding of any curve in the space.Thirdly, this paper obtained the error value between the manufactured curve and theoretical curve by means of Newton iterative method. The paper also programmed the error analysis programme by VC++6.0 so as to quantitatively analysis the relations among the theoretical profile, practical profile and the compensated profile, and this give a powerful prove for the new control method of the tool.At last, this paper completes the entity proplasm to the cam mechanism based on SolidWorks2000. At the same time, the paper also perform some thesecond development to SolidWorks2000 by VC++6. 0 so that the manufacture and mesh process can be simulated.
