A Study on the Intergrated Finishing Characteristics for Dies and Molds
금형의 복합연마 특성에 관한 연구
Abstract
Utomatic finishing process requires the development of high efficient and precision abrasive machining method for die and molds. This study describes the evaluation of the finishing characteristics, such as sufrace roughness, topography and material removal depth, of the electrolytic chemical mixed abrasive machining method. Experimental setup is composed of 3 axis machining center, a newly developed finishing attachment with constant pressure, electrode and electrolytic bath. Finally, we achieved a successful result that surface roughness is 0.01 .mu. m Ra and material removal depth is 145 .mu. m after 100 times repeat-finishing using electrolytic (0.8A,30V) mixed abrasive (#400 CBN, #320 Sic) machining method.
