Study on Evaluation and Characteristics of 100micro Drill Developed by the Special Abrasive Cutting System(Superabrasive/new wheel grinding process)

Abstract

INla have tried to obtain an optimal abrasive system that can irnprove the qpality of products or goods and the production efiiciency by estal)lishing the process system to rnanufatture 100micro drills and by experirnenting it in various ways. [[his paper have decided the optimum nomenclatures of 100micro drill for the shape clesign by considering the important factors such as the cutting poirrt angle, helix angle, web thickness, flute length and under cnt etc through the FEM analysis and was evaluated the characteristics of it owing to getting the high cpiality's products by various experi:rients.
