RAPID MANUFACTURING OF THE MASTER MODELS OF PDC BIT BASED ON FDM TECHNOLOGY
Flexible die forming is the main technology in manufacturing matrix PDC bits presently. In order to solve the problem that manufacturing process of the first moulds strictly relies on handmade, complex fixture and high precision machines, a method based on FDM technology to manufacturing the master models has been put forward. Through the 3D modeling and die design of bit under PRO/E circumstances, STL document of basis master model was obtained, it could realize the rapid modeling of master model by driving FDM equipment directly. It is proved that, this method could improve the precision and efficiency of the bit master models and reduce its costs.
