  • Online:2010-06-30 Published:2015-08-11

Abstract: AutoCAD is used as development environment to model Archimedes worm (ZA). Worm blank and cutter models are drawn with the drawing commands provided by AutoCAD. Worm is generated through simulation of the worm generation in machining using the commands including move, rotate and subtract. Program design of 3D parameterized modeling is developed with Autolisp language. The 3D model of Archimedes worm can be automatically generated with load of wlwg.isp program and input of the number of modulus and teeth and other parameters from users. The operation is simple and the design efficiency is improved greatly.

Key words: computer application, 3D modeling, generating, Archimedes worm
