| Abstract: | In this paper a method for expanding a moldboard surface is introduced. This method is based on MDT. Two procedures have been used in the method: (a) the method of straight lines projected on three dimension model of plow bottom is applied directly on MDT platform to get template curves; (b) the method of front view projected on three dimension model of plow bottom is applied directly to get realistic length of element lines.The method has the advantages of a convenient operation and reduction in time of calculation. A satisfied result can be achieved by using this method on the design of the two wing turning anti missplowing bottom. |
