The Trajectory Layout And Automatic Programming In The Welding Rapid Prototyping

As a new manufacturing method developed at the end of the last century, Rapid Prototyping , compared with conventional manufacturing methods , has the advantages of timesaving ,precision and complex modeling .and has been applied in more and more manufacture fields wildly. In recent years, Welding Rapid Prototyping at the aim of studying metal material shaped directly has become a international researching focus.In this paper, the development and application of Rapid Prototyping technology at home and abroad are introduced firstly. as well as the working principle , workflow and systematic makeup of Rapid Prototyping equipment. On the base of the comprehending and analyzing Welding Rapid Prototyping in existence, put forward realizing welding shaped metal part on numerical machine tool by automation programming adopting welding process and the idea of cumulating shape in Rapid Prototyping.A monotonous adapting to Welding Rapid Prototyping algorithm of scanning and hatching the delaminating section area is presented in this paper. Expound the whole course of distinguishing the section outlines are inside or outside, are the complex connecting area or the simple connecting area; Then dividing the complex connecting area into the simple connecting area, by monotonous dividing the simple connecting area, several monotone areas are generated. Finally produce numerical control shaped instruction codes.The focal point of the subject is to adopt Windows operation system as the developing platform, Choose VC++, OpenGL as the developing instrument, and adopt target's procedure design method ,Utilize emulation technology of the computer and computer cartoon technology, develop the automatic programming of the Welding Rapid Prototyping and emulation system. this systematic interface is friendly, it is easy to study to operate . Through combining the result of use with HUA ZHONG numerical control machining well. Meanwhile , it should indicate systematically to try out HUA ZHONG numerical control machining: Can comparatively produce correctly , shaping instruction codes in practical numerical control; Numerical control code emulation can trend, ocular one demonstrate that the torque shapes the sport orbit. And can realize that shaping simulation in trends of the metal par. In the article, expound the fact realization course, function module make up and operation method of systems software in detail originally.
