摘要

Preliminary to successful assembling, drilling of composites like carbon-fiber reinforced polymers (CFRP) is an important but difficult process. The anisotropic and heterogeneous structure of the laminates and the highly abrasive nature of the carbon fibers make it prone to critical damages in the workpiece as well as extensive tool wear. In this work, drill series with uncoated and diamond coated tungsten carbide hard metal tools were performed in two CFRP laminates with significant differences in their microstructure. The tool wear behavior and the corresponding workpiece damage were intensively studied to figure out the correlations between wear and delamination damage. Therefore, novel and well established methods in tool wear analysis and delamination assessment based on light optical microscopy were applied and critically evaluated.
