Abstract: |
This paper introduces the current status of digital manufacturing, and describes the design and manufacturing modeling methods for the parts with partial tolerances. The reasons why the design model can’t be used directly for CNC machining is analyzed, and the corresponding measures are proposed with verification examples. The method can break the barriers between design model and manufacturing model, and accelerate “nice” to “useful” in the integration manufacturing process of the three-dimensional model. |
