| Abstract: | A new process for hybrid rapid prototyping,which combines the advantages of deposition and milling,was proposed herein,and used ABAQUS finite element analysis software to test the temperature field distribution and the milling force,then manufactured a Multi-feature metal resistance piece successfully based on the analysis and experiment result.The measurement shows a dimensional accuracy of the test part within ±0.03 mm and a surface quality of Ra≤0.869 μm,which meet the requirements.The experimental results show that the technology can produce precision and full density of complex shape metal parts directly without die,shorten the development cycle and reduce the cost greatly. |
