초록

Among various materials, FCD500 is widely used in various fields of automobile components as it allows mass production through casting and its mechanical property is excellent. However, there are many problems in industry due to the fact that despite the wide use of FCD500, the researches about manufacture property of FCD500 are insufficient. Thus, this study conducted research on cutting manufacture property of FCD500, which is the most common manufacture method of FCD500 to suggest optimized tool and cutting condition. To achieve this, the study examined the change in cutting property based on tool material based on the most commonly used CVD(Chemical Vapor Deposition) coating tool and CBN tool, and examined the changes in cutting property by the form of CVD coating tool. The study measured cutting force, surface roughness of material after cutting, and amount of tool wear to examine the cutting property. The study gave variation in cutting speed of 280m/min and 500m/min, and fixed the feed rate and cutting depth for cutting condition to evaluate the changes by cutting speed.
