Three dimensional design and the rapid prototyping process
for a pistol barrel
Abstract
Based on the three-dimensional computer model,this issue mainly apply the rapid prototyping technology to make the shape into physical models. Firstly, a pistol barrel is specificly analyzed on actual samples to understand the structural characteristics of a pistol barrel, then applying Pro / E three-dimensional computer-aided design software to desvise the modeling of the pistol barrel；Through the design process, familiar with some basic functions of the Pro/E, I can devised it independently. Based on the three-dimensional modeling,then doing rapid prototyping process to make real production, including transforming three-dimensional model into STL format,then I import the STL format graphics into the computer.Using rapid prototyping machine HRP2004 system to pretreat the graphics,to formulate the right overall size arrangement and scaling of the three-dimensional shapes; Then in the HRP-ⅡB Rapid Prototyping System,I make the pistol barrel model, in this process,controlling the process and techniques of model preparation in the rapid prototyping mechanism; Finally，post-processing the model, including stripping, gluing and grinding process.Thus, a real pistol barrel is made out, and we basically complete the entirety of this design. The whole process fully demonstrate the application of rapid prototyping technology in practical production.
