Abstract:
Thanks to their adaptability, programmability, high dexterity and good maneuverability, industrial robots
offer more cutting-edge and lower-cost than machine tools to bring molded Carbon Fibre Reinforced
Polymers (CFRPs) parts to their final shapes and sizes. However, the quality of CFRP parts obtained with
robotic machining must be comparable to that obtained with a CNC machine. In addition, the robot itself
has to be very stiff and accurate to provide the same consistency and accuracy as their machine tool
counterparts. If the robot is not sufficiently stiff, chatter, overall vibrations and deviations in shape and
position of the workpieces will occur. Furthermore, during robotic machining of Carbon Fibre Reinforced
Polymer, the anisotropic and highly abrasive nature of CFRPs combined with the higher cutting forces and
the lower stiffness of the robot, lead to numerous machining problems. Therefore, robotic machining of
CFRPs stills a big challenge and need further research. In thi
s position paper, a methodology has been
developed and implemented to identify, understand and quantify the machining errors that can alter parts
accuracy during high speed robotic trimming of CFRPs.
