Compensation of Machining Error by Simulating Dynamic Deflection of Tool

Abstract

In aim to shorten lead-time of die fabrication, electrical discharge machining is being replaced with cutting. However, when cutting with tools of long extrusion length, achieving necessary accuracy becomes difficult due to chatter and machining remains. Therefore, cutting and measurement are repeated until satisfactory cutting conditions are achieved. Concerning this problem, we have developed a technique that analyzes dimension accuracy and surface accuracy before machining, by simulating dynamic vibration of the tool.
