Error control of CNC machine tools in automobile injection mold construction processing
Aiming at the ineffective control of spatial errors in the processing of automotive injection molds,which leads to low quality of automotive injection molds in practical applications,an error control method for machining automotive injection molds with CNC machine tools is proposed.Firstly,it establishes a spatial error model to an-alyze the errors generated during the machining of automotive injection molds by CNC machine tools;Secondly,taking mold production quality as the optimization objective and mold process parameters as decision variables,an error control objective function is established based on neural network algorithms;Finally,the white shark op-timization algorithm is used to solve the objective function and achieve error control.The simulation results show that the proposed method has high control accuracy and can reduce the degree of shrinkage during mold process-ing.The warpage deformation is always kept below 0.230 mm,and the error control effect is good.
