T he cutting process with a milling machine always causes a total tangential force, because the cross section of the slash is always changing. The purpose of this study was to determine how big the total tangential force of cutting S45C steel objects. It is planned to use the VFG 251 vertical type milling machine, with the dimensions of the workpiece sliding. length 100 mm x width 140 mm x height 25 mm and carbide chisel type finger milling (end milling) with a diameter of 030 mm which has 4 cutting edges. The parameters used in the process of machining the object are variations into cut 1, 1.125, 1.25 mm, tooth feeding 0.021, 0.025, 0.033 mm/tooth, and cutting speed 89, 115, 141 m/min. In this test, a load cell sensor is used to measure the force, which is connected to a strain gauge to convert the octagonal ring strain to an electrical quantity. That the results in the process parameters that most influence the cutting force are a, fz, v
