In this paper, performing experiment on abrasive belt grinding of glass reinforced plastic, the reasons why belt is slipping is analyzed under such circumstances when glass reinforced plastic is grinded by wet abrasive belt, a basis for the fiber reinforced plastic properties of an effective method of grinding is proposed, a solution that belt is slipping in the process is proposed too. At last, a basis is given to choose the correct hardness which on depend different parts of the hardness of the round of contacts.
The roundness error is researched in the process of coordinate polishing crankshaft crankpin with abrasive belt by measuring online. A detailed study on the tracing motion equations of the measurement system is made,so the mathematical model is obtained in this paper. In order to improve the in-situ measurement precision, the two-sensor tracing roundness error separation principle is proposed under motion stage. Finally, the conclusion that the source of errors could be determined initially according to online measurement of roundness errors is obtained, and then improving the accuracy by changing processing conditions timely.
The method of abrasive belt finishing slender piston rod was proposed in this paper, which based on low surface roughness weaknesses of low rigidity slender piston rod in the grinding process. And the ralation between the surface roughness and the grinding parameters was analyzed by the experiment research. The research result has a reasonably guidance for the actual manufacturing process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
