CRYOGENIC DEBURRING METHOD OF DRILL HOLE DEFECT IN CFRP

摘要

Disclosed is a deburring method of forming an ice layer surrounding burrs in order to remove burrs generated while drilling a CFRP and cutting the burrs and the ice layer surrounding the burrs. Generally, it is difficult to remove burrs formed on the CFRP since the burrs are formed by protruding carbon fiber. The deburring method according to the present invention is effective since the ice layer supports the carbon fiber. Because the ice layer is used to support a defect part of the burrs, an increase of cutting load is very slight, there is no influence on tools and a workpiece, and the deburring method according to the present invention is an eco-friendly process capable of performing deburring very effectively. The deburring method according to an embodiment of the present invention can effectively remove the hole defect portion generated in an expensive CFRP, thereby preventing the workpiece from being wasted by drilling defects in order to enhance productivity.;COPYRIGHT KIPO 2019
