Testing the Cutting Depth Capability of A 16 Mm Hss-Co Endmill on S50c Material Using the Lagun Fu 100 Milling Machine

Abstract

The milling process is a conventional process that requires a cutting tool harder than the workpiece material. In the milling process, one of the cutting tools or cutters used is the HSS endmill type which has a hardness value of around 735 HB (Hardness Brinell). The material used in this study is an S50C which has a 172 HB. The machine used in this study is a Lagun FU 100 milling machine. The testing process uses a cutting speed of 18 m/min, a spindle speed of 350 rpm, and a feed rate of 30 mm/min. The largest tangential force that occurs is obtained when performing a cutting depth of 40 mm with a value of 2220 N, the torque on the cutter is 17.76 Nm, and the power on the motor is 0.897 kw. The calculation of the deflection on the chisel obtained the largest value of 0.093 mm based on simulation, while the largest stress value based on the simulation results is 224,5 N / mm ^ 2. The test results on the Lagun milling machine showed that the HSS-Co end mill was able to cut S50C material to a depth of 40 mm.
