【Abstract】 This paper deals with a theory and methods for the Computer Aided Design of machine element tolerance and introduces an approach to design interface between the data and the AUTOCAD. Based on the theory and methods, the author has developed a system of the CAD of tolerance for command machine element and a it’s interface to foe AUTOCAD. It has ben proved, that the system has right principles, conforms to the National Standards, the theory is correct, and is convenient for use. It is significant to popularize the method in the machine CAD.更多还原
