Design and Verification of ADU Drilling Tools for Unidirectional Composite Hole Making
In order to solve the problems of long development and testing period of ADU drilling tools,high cost of prototype tools in pilot production and damage in the holes making of composite stacks,CNC machining equipment is used to test straight shank hard alloy tools with different cutting edge types and same machining parameters of ADU tools.The in-fluence of cutting edge structure on the quality of holes for composite materials is compared,and then customize the threa-ded shank tools to carry out the validation of ADU drilling by determining the optimal structure,a convenient and fast path to solve the problem of ADU drilling damage with lower cost is found.The references for the selection and testing of ADU drilling tools for composite stacks is provided,the efficiency of tools development is improved,and the production and R&D cost is reduced.
