CAD/CAM Integration For Rubber Overshoes

Up till now , in some middle - small production enterprises of rubber overshoes in our country, the level in designing and manufacturing rubber overshoe mould is still relative backward, main mode of manufacturing mould is manual operation and its quality and grade is not high . Its production period is long, which more and more difficultly meets the needs of market. In order to change the backward situation, it is very neccessary to apply CAD/CAM technology in production for rubber overshoes . Based on a real applying project, the deep study has been made theoretically on " CAD / CAM integeration for rubber overshoes " in this paper, which will raise the level of designing and manufacturing rubber overshoe mould.First of all , proceeding from actual condition of middle - small production enterprises of manufacturing rubber overshoes , the overall developing plan of the system has been worked out. Using economic NC milling machine tool and two classes computer control, and taking full advantages of software, this system can perform the main function of full function NC system and supply a set of CAD / CAM technique suited for the enterprises of manufacturing rubber overshoes, which can bring economic benefit for these enterprises.Secondly, to counter contour curve for large sole of rubber overshoes , the way of linear circle arc spline of two dimensions curve fitting has been raised in this paper and AutoCAD has meanwhile been applied in CAD / CAM integeration system of rubber overshoes mould, and also a whole set of software and hardware technique developed , and the selecting way for optimizing tool path worked out . This way may make NC machining free running minimun. Its NC command system is not only simple and convenient but also of complete function. It can effectively control the movement of machine tool.Finally, a number of tests have been made in order to examine the function of whole system, and its functions have been improved through the tests, and the reference values for some machining process parameters given , and some gujiding opinions for using the system put forward , and myself s view point for the shortcomings of the system and how to improve it in future has been made .
