To solve this problem, this investigation provides a CAD model which is established by the method of feature modelling, and deals with the description method of parts in the model, the modelling method of basic geometrics, database Construction and its application in the HTD-CAD/CAPP integrated system.
By deep research on NURBS modelling method, a new modelling function in NURBS for skinning surface bidirectional interpolating via complex curves is realized in SuperMan CAD/CAM integrated system, completely based on NURBS method.
Because of the ability to settle the problem of modelling of 3-D discrete data curved surface for the products with complex configuration and irregular shape and boundary,the triangle curved suface modelling method has become the central issue in the research of CAD/CAM technology.
Through the comprehensive analysis of various factors that affect the mine operatoin results and by the systematic modelling method and the fuzzy comprehensive evaluation method,optimizatoin study was made on the cut off grade,industrial grade,loss rate,dilution rate and beneficiatoin feed grade.
This paper gives an account of the principle and modelling method of the electric model experiment on machine end-winding magnetic fields with conductive paper and two groups of experiment and analyses their results as well.
