塑模的逆向工程及NC加工

Reverse Engineering of Plastic Die and Its NC Machining

本文以电话机外壳复杂曲面及模具造型为背景,利用接触式三坐标测量机,准确、快速地测量出电话机外壳曲面的若干数据。通过数据处理,传给大型的Pro/ENGINEER曲面造型系统。探讨在Pro/EN-GINEER环境下,塑模的逆向工程框架及实现模具复杂曲面—曲面重构(建模)—加工一体化方法。

Based of research on the complex surface of phone shell an d its die design,the main data rapidlyand accu-rately obtained from the surfaces of the phone shell by3D measurement machine.With processing the data have be en transferred to Pro/Engineer curved surface designing system for probing int o plan of reverse engineering and method of integrated representation of the com plex surface and NC machining.
