Abstract: In order to solve the complexity of the problem, through the uneven processing technology, processing technology, cutting surface, etc., the optimization design of this path of vibration-assisted cutting is studied in all aspects, a path optimization model, in the transition zone planning circle, the mathematical plug-in method is used to demonstrate the method as the optimized position of the roadmap. For specific research objects, the simulation software path is used to simulate, and the results are initially formed. The proposed site design re-expands the earlier algorithm and the algorithm is reduced by 27%; for the complex technology transition area, the small program that optimizes the transition area through the proposed path planning is available, and does not involve overcutting phenomenon; The transition zone analysis; the obtained surface topography was carried out, and the calculation results showed that the surface roughness Sq of the optimized path decreased from 0.0059 to 0.0045, and the surface roughness Sa of the optimized path decreased from 0.0067 to 0.0038, and the surface quality of the optimized path algorithm was improved.
