ANALISIS WAKTU DAN UMUR PAHAT KARBIDE PEMBUBUTAN PEMBUATAN TOOL HOLDER MATERIAL MILD STEEL.

CNC Lathe machines are machines used in the manufacturing industry to produce components for the engineering sector in large quantities quickly. This study aims to find out the time of the tool holder manufacturing process and also to find out the time of the chisel age. This study used cutting speeds of 190 m / min, 180 m / min, and 170 m / min, feed rate 0.3 mm / round, depth of cut 0.7 mm. Based on the research conducted for the time of making a tool holder is 7:25 and the use of a chisel required for the manufacture of one tool holder is 1 piece. The Ra value obtained is also very influential with the age of the chisel. [ABSTRACT FROM AUTHOR]
