Abstract
In order to effectively control the machining error of globoidal cam profile, an adaptive tool position error compensation algorithm is proposed. According to the space meshing principle and the rotation transformation tensor method, the actual working profile equation of the non-equalization diameter machining globoidal cam is established. The objective is to minimize the maximum deviation of the actual tool axis, and search the optimal tool offset and direction during machining to achieve adaptive compensation of the tool position. When the tool radius compensation amount Δr=3mm, the theoretical value of the maximum normal error of the cam profile is close to the simulation value. The result validates the effectiveness of the tool position control technique of the adaptive algorithm for machining error compensation, thereby the machining accuracy of the globoidal cam is improved greatly.
