Research Status of High-quality Small Hole with Large Aspect Ratio in EDM
The hole machining faces the difficulty of debris evacuation in the case of large aspect ratio(LAR),this paper mainly reviews the evolution of machining deep hole with EDM and related methods.The current status of deep hole machined by EDM is discussed from the aspects of tool electrode design,path planning and extra assistance from energy fields.Meanwhile,methods to improve the surface quality of micro hole are introduced.Finally,the critical obstacles and future trends in the LAR micro hole machining with EDM are discussed.
