Abstract： The surface of the track board requires extremely high flatness to ensure the smoothness of train operation. When using a single layered unit vector for mold forming，it cannot fit well with the complex asymmetric surfaces and thickness transition areas of the track plate， resulting in obvious step marks on the surface during cuting or construction processes. Causing unevenness on the surface of the track board， affecting the overall quality of the track board. Therefore，a hierarchical control method of track plate mold forming based on genetic algorithm and industrial personal computer （IPC） is proposed. Design a hierarchical control architecture and select different control parameters. And introducing the idea of layering，an optimization strategy for layering unit vectors is constructed from three aspects： support area， forming time，and surface roughness. Through genetic algorithm，the layering strategy and cutting parameters are intelligently optimized based on diferent parts and geometric characteristics of the track plate. The experimental results show that the average absolute error between the track plate prepared by the proposed method and the standard component is only 0.01mm ，the surface roughness is significantly reduced，and the forming time is shortened by more than 30% . This system effectively solves the problems of insuficient accuracy and low efficiency of traditional methods through real-time data feedback and adaptive optimization， providing innovative solutions for the mold forming of complex curved parts.
