초록

Carbon Fiber Reinforced Plastic (CFRP) materials which are superlight in weight and have high strength have recently been applied in the automobile and aerospace industry, etc. to achieve high fuel efficiency. CFRP is termed as ‘difficult to cut material’ due to its unique material properties. It’s considered to be highly sensitive in processing due to its laminated structure which would pose some challenges such as delamination, Pull-out, Burr and Uncut. Due to this, it’s maintenance and treatment costs are high. There are also limitations in the conventional Gantry Machine in 3D shape cutting of CFRP materials. To counter this challenge, a robotic abrasive waterjet system with the following features has been developed and installed on site; a high-pressure pump, monitoring system and a catcher for 3D Shape cutting., It’s performance has been successfully proved. Based on the result, we discovered that a 6 axes robot could execute 3D shape cutting of car hood due to its high movement flexibility. In the future it is projected to fulfill more kinds of CFRP materials cutting test on many car brands.
