Technology Research of Front-end Module Based on Online Measurement and Dynamic Forming Process
Through the design of the optical online measurement system and with the Profibus field bus applied as the communication protocol,the actual measurement deviation data of the BIW is used to adjust the molding process parameters of the front-end module installation point in real time and dynamic.The cumulative tolerance of the front-end module is corrected online to make it return to the theoretical position of x,y,and z,which realizes the secondary molding of the front-end module installation point.Tolerance simulation and actual production confirmation are carried out.The designed method greatly improves the accuracy and adaptability of the dimensional control method,has good feasibility in terms of the dimensional accuracy of the front facial and is of promotion value.
