the Characteristics of Cutting Force and Surface Roughness in case of Endmill Wear

엔드밀 마멸에 따른 절삭력과 표면조도의 특성

End Milling is avilable for machining the variable shape of products and has been widely applicated in many industries. To manufacture precise products a surface roughness has to be noticable as a improtant parameter. In end milling the research for tool wear has been insufficient because the tool shape and the cutting geometry are complicated. In this paper the pattern of endmill wear is investigated and the machinability is evaluated. As finding out the characteristics of cutting force and surface roughness the effect of endmill wear on machinability is investigated.
