In recent years, interior decoration has gained popularity in China, making the optimization of the process for interior hardcover materials and processing technology based on the principles of artistic beauty a significant task. This paper introduces a process design method using the linear discriminant analysis algorithm and explores the application of artistic beauty principles in the processing technology of indoor hardbound materials. The research begins with a summary of the current research status, followed by an investigation of various aspects of processing technology. It identifies five factors influencing the efficiency of processing indoor hardbound materials and optimizes the traditional process method accordingly. The proposed scientific machining model for hard mounting materials is then presented. Finally, a design experiment is conducted to verify the feasibility of the machining model. The research findings indicate that the processing optimization model based on the linear discriminant analysis algorithm effectively enhances the processing quality and efficiency of indoor hard decoration materials.
