Research on Compensation Technology of Automobile Panel Die Surface Based On Reverse Engineering

Aiming at the problem of the automobile panel die surface compensation technology which are difficult to guarantee quickly and occupies most of the processing cycle, the method of data analysis based on reverse engineering is put forward. The main steps first point cloud acquisition by non-contact measurement, Secondly point cloud pretreatment, And data model comparison in Geomagic qualify, Section deviation value obtained by 3D and 2D compared. Fitter to compensate the deviation values and rules are obtained. Die face compensation equation are established to achieve rapid acquisition mode of the compensation amount. This method is used to determine the compensation amount of the car door. The results show that the method can quickly and accurately determine the amount of compensation which provide theoretical basis for the new mold in the future development.
