| It is easy to plug the surface of the traditional grinding wheel with the swarf for the abrasive is very small. As a result, the grinding wheel is hurt by the grinding thermal and it is disabled prematurely. The processing quality and efficiency of the components has been hindered to be improved. To solve the shortcomings of the traditional grinding wheel, one of the most effective methods is that the abrasives or micro-stacks of abrasive and abrasive spacing is arranged on the grinding wheel surface with the requirement of the scientific.To solve this problem, this paper bases on National Natural Science Foundation and Liaoning Provincial Natural Science Foundation's research claim, do a series of optimize researches about technics of grinding wheel with controlled distributing abrasives and its grinding performance. To be specific, it contains that the effect of different type of electric current on the growing speed of Ni-Co deposit has been researched by doing some tests, and obtain account parameter about the growing speed of deposit in definite electric current range, test the plating liquor's decentralization and its adaptive current bound by using Hull trough experiment. And this paper also do some changes about technics of grinding wheel ,in order to make the abrasive is easy to adhere to the surface of the grinding wheel. Base above researches, can produce the controlled distributing grinding wheels with controlled abrasive embedding depth and same highness micro-stacks of abrasive.According to which kind of micro-stacks of abrasive distribution on grinding wheels is more reasonable, and has a better processing performance. The author based on the actual grinding process, educing the course track equation of any micro-stacks of abrasive on the surface of the grinding wheel. And by using MATLAB software to analog simulate course track equation of the micro-stacks of abrasive to educe validate the rationality of micro-stacks of abrasive's distribution rule, and the advantage and disadvantage between different diameters of micro-stacks of abrasive. The result is that the micro-stacks of abrasive which has a less diameter and close distribution can have a good performance in the grinding process.Basing on above researches, according to the CFRP, which is hard to process and easy to jam to do some actual grinding experiments by using the controlled distributing grinding wheels, and use controlled distribution and random grinding wheels to do the grinding contrast experiment,come to the conclusion that the controlled distribution grinding wheel's grinding performances are much better than the traditional ones. And investigate that the grinding technics parameter which is suit for this kind of grinding wheel. Comparing with different distribution of grinding wheels' grinding performance, come to the conclusion that when the grinding wheel's X is 40% ,and each micro-stack has 4-6 abrasives, it have the best grinding performance. |
