EXPERIMENTAL RESEARCH ON MACHINING WITH DLC DIAMOND COATED MILLING TOOLS OF ALUMINUM ALLOY PARTS USED IN THE AERONAUTICAL INDUSTRY

Abstract

The present work is intended to be a presentation of the results obtained when conducting an physical experiment of milling the parts of the Airbus A350 aircraft structure, using cutting tools with uncoated inserts and DLC diamond coated inserts, using several cutting parameters. The material we chose for the experiment is 2196 T8511, alloy of aluminum with lithium. The paper presents the equipment needed to complete the experiment, a synthesis of the types of materials used is made. The results of the experiment, the roughness of the generated surfaces and the durability of each set of inserts are represented by graphs. The objectives of the experiments are to maintain the roughness within the limits required by the customer through the indications on the technical drawing and to have concrete values of the durability of the inserts used depending on the material and cutting parameters used.
