Abstract

The issues arising in production facilities engaged in processing composite materials are considered. Specifically, the solutions to problems encountered in the mechanical processing of composites are analyzed based on foreign scientific research and proprietary solutions employed in the enterprise. The main issues addressed include delamination of pultruded glass fiber reinforced plastics and the selection of proper cutting fluid for processing. A mathematical model for calculating cutting regimes has been developed. The mathematical model has been validated through experiments to determine the delamination coefficient with the calculated cutting regimes. The machining process of the workpiece has been simulated in the Ansys system using the Lagrangian approach with the finite element method. A computational experiment has been conducted using the PRIAM software. A methodology for designing final milling operations based on the criterion of limiting delamination and ensuring the specified surface roughness of laminated glass fiber reinforced composites has been developed. It has been established that with a constant cutting speed and depth of cut, and varying only the feed rate, delamination increases with increased feed rate. It has been found that with the same depth of cut and feed rate, and varying cutting speed, the surface quality is satisfactory, indicating a lower delamination coefficient. The mathematical model based on the conducted experiments has proven to be practical and effective for determining an approximate delamination coefficient. The obtained results have proven to be practical and are used in enterprises engaged in the mechanical processing of glass fiber reinforced plastics.
