摘      要：The equipment used in various fields contains an increasing number of parts with curved surfaces of increasing ***-axis computer numerical control(CNC)milling is the main parts machining method,while dynamics analysis has always been a research *** cutting conditions determined by the cutter axis,tool path,and workpiece geometry are complex and changeable,which has made dynamics research a major *** this reason,this paper introduces the innovative idea of applying dimension reduction and mapping to the five-axis machining of curved surfaces,and proposes an efficient dynamics analysis *** simplify the research object,the cutter position points along the tool path were discretized into inclined plane five-axis *** cutter dip angle and feed deflection angle were used to define the spatial position relationship in five-axis *** were then taken as the new base variables to construct an abstract two-dimensional space and establish the mapping relationship between the cutter position point and space point sets to further simplify the dimensions of the research *** on the in-cut cutting edge solved by the space limitation method,the dynamics of the inclined plane five-axis machining unit were studied,and the results were uniformly stored in the abstract space to produce a ***,the prediction of the milling force and vibration state along the tool path became a data extraction process that significantly improved *** experiments were also conducted which proved the accuracy and efficiency of the proposed dynamics analysis *** study has great potential for the online synchronization of intelligent machining of large surfaces.
