Abstract:
The cutting force and tool deflection models of ball-end milling cutter are established for the problem of tool deflection-induced error. The machining error model is proposed for the tool deflection-induced error of the ball-end milling cutter and the model is integrated into the NC machining geometric simulation prototype. The simulation prediction function of tool deflection-induced error is realized. Various experiments verify the validity of the proposed error model. The result shows that the proposed error model can accurately predicte the machining error in the NC mill machining.[著者文摘]
