Research on abrasive wear characteristics of electroplated diamond tool during drilling carbon fiber reinforced plastics
摘要
Abstract
During the process of drilling carbon fiber reinforced plastics （CFRP）, it tends to effectively reduce or eliminate manufacturing deficiency, such as burr and delamination using electroplated diamond step-core drill whose service life mainly depends on the service life of electroplated diamond abrasive. Therefore, systematic statistical observation was carried out on the abrasive wear patterns of electroplated diamond. Investigations show that using the electroplated diamond step-core drill, three unique stages of diamond abrasive wear can be observed during the process of drilling T300 CFRP, which involves initial instable wear stage, mixed-wear stage and normal wear stage. The wear patterns of diamond abrasive and drilling thrust force have a significant linear relationship. With the growing of hole numbers, the thrust force gradually increases, but diameter tolerances of the holes are still stabilized in a range of 0. 024 mm after the initial instable wear stage.关键词
