Abstract


Rapid prototyping manufacturing technology driver shaping method to quickly and liberalization of the advantages of forming an arbitrary three-dimensional geometric entities, has a wide range of applications in many areas, because of the add-in and digitized direct metal material forming metal functional parts world rapid prototyping manufacturing technology development direction. Electrochemical deposition technology refers to the metal cations in the bath is continuously deposited on the cathode surface and thus forming part of a precision, increased material processing technology. Its biggest advantage is you can get high-precision, high-finish surface of the part, can be accurate, precise replication complex surfaces and fine lines, but there are also slow deposition, poor uniformity of the deposited layer and heavily dependent on the mother mold, etc. inadequate, therefore, its application is confined in sophisticated microfabrication areas to. This article rapid prototyping manufacturing technology, combine electrochemical deposition technology and CNC technology, good use of the advantages of the three, a direct rapid prototyping technology for manufacturing metal parts - CNC constituency electrodeposition rapid prototyping technology, the technology electrochemical deposition directly molding and manufacturing metal parts, greatly broadens the traditional rapid prototyping manufacturing technology research areas. Rapid prototyping technology CNC constituency electrodeposition theoretical analysis and process test research, this paper studies the content is as follows: (1) The reasonableness based on the analysis of rapid prototyping manufacturing technology, electrochemical deposition technology and CNC technology integrated with each other, CNC constituency electrodeposition rapid prototyping technology provides a new way for the rapid prototyping of metal parts directly. (2) analysis of the characteristics of the CNC constituency electrodeposition process of rapid prototyping, the development of a rapid prototyping machine CNC constituency electrodeposition system hardware structure to build and develop the control software. (3) analysis of CNC constituency electrodeposition rapid prototyping data processing, data interface - STL file, its main defect repair, and laid the foundation for the development of the realization of slicing software and scan path. (4) Research CNC constituency electrodeposition electrodeposition mechanism of rapid prototyping, and start from the anode material, end shape and deposition model, Preparation of core components anode head. (5) rapid prototyping CNC constituency electrodeposition path planning, the existing rapid prototyping commonly used in scanning mode, parallel straight lines staggered gap reciprocating scan, details the realization of the scan path algorithm, combined with test preparation shape rules, a clear outline of the metal copper parts. (6) the analysis of the main factors influencing the molding quality, mainly include two aspects of the the STL model parameters and process parameters, a detailed analysis of the impact of process parameters on the locality, a set of optimized process parameters and improve electric deposition rate, and hierarchical algorithm optimization ways.
