Research on automatic machining method of large-size thin-wall machinery parts based on lom technology

In order to solve the problems mentioned above,LOM technology is introduced to design and study the automatic processing method of large-scale thin-walled mechanical parts.According to the characteristics of large-scale thin-walled machine parts processing,LOM technology is used to solve the processing target surface.On this basis,the information of the processing target surface is extracted by cross-section method.According to the information of the processing target surface,a three-dimensional steady cutting force model is established.Based on the three-dimensional steady cutting force model,the NC machine tool processing program is compiled by UG software.With the implementation,the automatic processing of largescale thin-walled mechanical parts is realized.Compared with the existing automatic processing methods for large-scale thinwalled mechanical parts,the proposed automatic processing method for large-scale thin-walled mechanical parts greatly improves the processing efficiency and quality,fully demonstrating that the proposed automatic processing method for large-scale thin-walled mechanical parts has better processing performance.
