Analysis of the age and status of carbid with alumnium molding without RPM variations and power rapidity on lathe haas CNC machines at PT. XXX

Abstract

In everyday life we are not deprived of a technology, one example in the application of technology in the field of machining with the use of CNC machinery, CNC is that this machine is a machine used in the manufacturing process that usually uses computerized control and machine equipment. The most dominant advantage is the speed in the production process so it is suitable for mass production. The purpose of this study is to analyze the edge wear (VB) and determine the value of the n exponent and CT constant of the equation of Taylor's peak age for the peak life of the carbide with the aluminum material and to know the influence of the speed of rotation, feed speed, and cut depth on the machining process on the peaking life of carbide. In this study there are several parameters used namely with RPM 1000, 1800, and 2000. With the movement of 0.25 mm / rev, 0.15 mm /rev, and 0.05 mm / re with the data obtained which was later analyzed, this study can conclude, the life of the carbide in the process of cutting aluminum cylinders, obtain the exponent value n = 0.39 and the CT constant at a1 = 694.45, the constant CT at a2 = 659.66, the CT constante at a3 = 666.85. Then obtaining the aging age (T) will decrease, that aging at cutting speed (Vc1) = 81.64 m / min and n1 = 1000 rpm, i.e. 240,575 min. This study is influenced by the depth of the cutting (a1) = 1 mm, at the cut speed (vc2) = 141.3 m/ min. and N1 = 1800 rpm (t) = 51.75 min., and the shortest aging time occurring at a cutting velocity (Vc3) = 153,86 m / m. This research will also affect the age of its cutting at a certain depth (n)
