Topic: Research and design tasks and contents of virtual machining and virtual forming simulation technology (the main problem to be expounded in this paper) Virtual machining and virtual forming simulation technology is an important means adopted in the field of mechanical machining and material forming. The reliability and feasibility of the scheme are verified by making a digital model on the computer and simulating the virtual machining process. For machining, simulation can directly generate machining codes, which can be used for NC machine tools to finish machining parts. The simulation of material forming can verify the feasibility and reliability of the forming method, thus shortening the design cycle and reducing the production cost. This graduation project mainly requires students to master the application of virtual machining and virtual forming simulation technology in this industry, and look forward to its development. The content is as follows: 1. Generation and development of virtual machining and virtual forming simulation technology. 2. Introduce the commonly used virtual machining and virtual forming simulation software in the field of material forming. 3. Brief introduction of key technologies of virtual machining and virtual forming simulation technology. 4. Application examples of virtual machining and virtual forming simulation technology (one for virtual machining and one for virtual forming simulation). 5. Application prospect analysis of virtual machining and virtual forming simulation technology. 6, the other according to the relevant provisions of the "2009 graduate design (thesis) specification requirements".
