Study on the Cutting Characteristics of Drilling CFRP Using Exterior Materials of Automobile

Abstract:

Carbon fiber-reinforced plastic has been applied in various industrial areas due to outstanding mechanic characteristics including high strength and hardness as well as light-weight. For the mechanic combination after the CFRP molding, hall processing is required. In this study, generally used carbide drill and TiAIN coating carbide drill were used to proceed the experiment. Afterwards, carbide drill where point angle was changed into 90° was manufactured while evaluating thrust force and tool wear. In the experiment of carbide drill and TiAIN coating carbide drill, thrust force was reduced when major axis rotating speed increased. However, it was not much influenced by changes in moving speed. In addition, TiAIN coating has not much influenced on the processing feature. Tools with point angle changed into were measured 90° with lower tool wear and thrust force compared to two other tools while obtaining outstanding tool performance.
