| 摘 要： | 以微机为平台，使用通用的传感器及普通数控机床对汽车覆盖件等零件进行实物采样，获取空间三维坐标点集，对数据进行数字滤波、线性化及光顺处理，清除随机误差、系统误差，保证造型精度。采用Ａｕｔｏｄｅｓｋ公司的造型软件ＭＤＴ及自编程序在计算机中生成实物模型。这对ＣＡＤ技术在企业中的运用具有重要意义，促进了微机ＣＡＤ／ＣＡＭ系统在国内的推广应用。

| Abstract: | This article describes the process of making samples of real object for complex automobile parts by ordinary sensor and ordinary numerically controlled machine tool on the base of computer. The coordinate data from real object are obtained and error measuring is eliminated through digit filtering,linearization and smoothness for restricting the precision of construction. The modeling of real object is obtained by using self made program and surface modeling software MDT.The work herein is important for technology of CAD to be exerted in general factories and is helpful for CAD/CAM system to be spread in the whole country. |
