In the operations of grinding of profiles [1], a wrong selection of the grinding machine grinding wheel affects greatly as a whole and the profiles of the stator sheets. For this reason, the diameter of the grinding wheel depends primarily on the spokes of the profile of the stator. The consideration and analysis of this unit is required to avoid deformations on the surface of the profile during the grinding process, which may arise as a result of the uncertainty in the dimensions of the grinding wheel [2]. Also, the roughness on the surface of the profile of the stator leads us to search for a method suitable for the selection of this. A procedure that allows the optimal selection of the diameter will be displayed in this work.
2 tools employed
The program Matlab and Qbasic to simplify results and extraction graphs [3] has been used in this analysis.
3. Results and discussion
The results obtained are indication of accuracy of the analysis made in this work. In the table I different radii are obtained to select the grinding wheel. Take the child and is rounded up to the next integer. The mathematical expression for the obtaining of these radios, this given by the function of the characteristic of curvature RADIUS for the role of the analyzed profile.
4 Conclusions
1. The method used in this work, for determining the diameter of the grinding wheel to carry out the grinding of the profile, is the most appropriate method to reduce the roughness in the rectified surface of stator.
(2) If the diameter of the grinding wheel is inappropriate for the grinding of the profile of the stator, this will influence the geometric integrity of the profile and, as a result, will produce great vibrations in the fluid of the stator. For this reason, your selection should be conducted in such a way that guarantees a correct grinding.
