Design and Application of High-Performance Adhesive Bonding Surface Roughening Experimental Platform

To meet the surface treatment requirements of large-sized bonded components in aerospace, this paper designs an experimental platform for surface roughening that integrates industrial robots, active compliance force control systems, and multi-mode grinding units. A software system with trajectory planning, dynamic parameter regulation, and hardware coordination control is developed. Multi-level experimental teaching contents were designed. Through experiments on aluminum-aluminum alloy specimens, the optimal surface roughness and texture direction are determined. The best process parameter combination is obtained through response surface method optimization, verifying the effectiveness of the experimental platform. This experimental platform can not only be used for undergraduate experimental teaching, but also serve as a research development platform for postgraduate students in related fields to optimize the roughening processing parameters of bonded components.
