Effect of chilled air on tool wear and workpiece quality during milling of carbon ﬁbre-reinforced plastic

Carbon fibre reinforced plastic (CFRP) is a composite which has the best strength to weight ratio among the construction materials. It becomes valuable as the demand for this composite has increased dramatically especially in automobile and aerospace industry. The need in these industries such as...

The need in these industries such as light weight, but retain high strength, make CFRP better choice than steel. CFRP is also known as an expensive material, since an expensive chemical treatment is required in the fabrication process.

The improvement in tool life while applying chilled air during machining of CFRP is 1.6% and 12.1% at lowest feed rate and cutting speed; while 31.8% and 45.6% longer tool life of carbide cutting tool is observed at highest feed rate and cutting speed under chilled air machining compared to room temperature machining. The delamination factor of CFRP is also found to improve at higher cutting speeds during chilled-air machining.
