This paper describes the structure and technology of intelligent manufacturing systems for electrical equipment oriented to industry 4. 0,introduces the theoretical approximation algorithms of the size of the sheet- metal expansion in the automatic production process for the cabinet,derives the mathematical expressions of the bend compensation values,establishes the experimental model to determine the bending compensation coefficients,calculates the expansion coefficients of sheet- metal made from different materials by different bending mold based on the method of regression analysis,then converts them to the bending factor for digital design platform Creo. The results show that the experimental analysis method based on the regression analysis can be used to accurately count up the compensation coefficients of the sheet- metal expansion. The important data is provided for automatically expanding the sheet- metal by the design platform of the intelligent manufacturing systems for enterprises.
