Reverse yougurt shape of a barrel
ABSTRACT: This paper presents how to use UG and surfacer software on the reversing design of the mold problem, the issue raised for the following reasons: 1. In the CMM we can be able to quickly and accurately measuring a large number of products already on the surface coordinates. 2. Points in a dedicated software surfacer can be easily handled more accurate will be adjacent to the point of curves and surfaces. 3. UG software products to be able to recover entities, and to further reverse the reverse die design and manufacturing integration.
Point cloud data and pretreatment of surface reconstruction is the reverse engineering of key technologies, while UG software has powerful features of surface modeling, but the point cloud data pre-processing functions quite weak. Surfacer to this paper as an intermediary software, the completion point cloud data preprocessing, the increase in the UG reverse engineering software on the efficiency and accuracy. This paper on the work are as follows: 1.The CMM on a variety of methods and the development of the status at home and abroad. 2.Point cloud sort of way, the initial establishment of point cloud relations between the topology, to a certain point cloud the integrity and remove noise points. 3.Surfacer use development tools to sort and the completion point-to streamline and point-fitting curves and surfaces, and to achieve a fitting surface interface displayed on the UG. 4.UG to the surface processing and modeling software as a tool for physical rehabilitation and reverse model.
