考虑刀具底刃切削的CFRP铣削力精确建模研究
Research on Precise Modeling of CFRP Milling Force Considering Bottom Edge of Tool
摘要
Abstract
A mechanistic based cutting force model was proposed for predicting forces in milling of carbon fiber reinforced polymer composite (CFRP),in which the effects of the cutting edges on the tool periphery and bottom were both considered.Through experiments,the force contributions by peripheral edges and bottom edges were recognized and analyzed.The influences of the instantaneous chip thickness,fiber cutting angle and cutting speed on the specific cutting forces were recognized and modeled based on BP neural network.The proposed approach shows better agreement with the experimental.The result shows the prediction accuracy of force can be improved when the bottom of cutter blade was incorporated in the model.The feasibility of BP neural network for cutting force modeling was also verified.关键词
