The condition of the cutting tool when drilling composite materials is the controlling factor for the surface integrity of hole produced. The high rate of tool wear when drilling composite materials makes finding a way to monitor the condition of the cutting tool without interrupting the drilling process a great necessity. Inspecting the condition of the drill between or during the drilling process is not practical or economical. In an attempt to tackle this problem, a new approach of on-line tool wear monitoring method using an air-coupled audio microphone is proposed. An experimental investigation was conducted on multi-directional carbon fiber reinforced plastic (CFRP) composite material using a high speed steel (HSS) drill. The result shows that, the amplitude of the acoustic signal from the microphone decreases when the amount of flank wear increases and the amplitude of thrust force and torque increases with the increase of the flank wear. This result demonstrates that the proposed approach can be used as an effective and economical tool for on-line monitoring of cutting tool condition.

According to the characteristics of NM360, a contrast experiment for drilling performance in YG8 cemented carbide twist drill, high-speed steel twist drill and factories used in coating the ordinary high-speed steel twist drill has been done. Using microscope to observe tool wear, we found that the flank wear and chisel edge wear are the main wear of the drill. The carbide tools has a better ability of resistance to plastic deformation, abrasive wear and adhesive wear than high-speed steel cutting tools. The coating tools are better to resist abrasive wear and adhesive wear than uncoated tools.Deformation of carbide cutting tools, abrasive wear, ability than high-speed steel cutting tools.

Minimum quantity lubrication (MQL) has been used as an alternative solution for flood cooling as well as dry machining. However, the benefit of MQL is only realized in mild machining conditions as the heat generation during more aggressive machining conditions cannot be effectively eliminated by the small amount of oil mist being applied during MQL process. To extend the applicability of MQL to more aggressive machining conditions, we have developed a potential additive to MQL lubricant. After the preliminary wetting angle measurement of the various lubricants, one commercially available MQL vegetable oil was chosen, which is then mixed in a high-speed mixer with exfoliated nanographene particles. The resulting nanoenhanced MQL lubricant was evaluated for its tribological and machining behaviors together with the suspension stability of the mixture. Friction coefficients of new nanoenhanced MQL oil were also measured in terms of loads, speeds and lubricants. Finally, MQL-ball milling tests with nanographene enhanced lubricant were performed to show a remarkable performance improvement in reducing both central wear and flank wear as well as edge chipping at cutting edge.
