Behavior of Insert Oxide Results of Dry Machining Stainless Steel AISI 301
Abstract
Dry machining is becoming trending in the manufacturing industry today. Besides being environmentally friendly, it can also reduce production costs. The consequence of dry machining is high-quality cutting tools. If this is fulfilled, the results of machining products can be relied upon. The cutting tool which is considered to have high quality is insert. Various types and shapes of inserts are produced by the cutting tool industry with two, three, four cutting corners, and even eight cutting corners. Until now there has not been a cutting tool industry that claims to have found an insert or cutting tool that is said to be perfect, each cutting tool has advantages and disadvantages so that development continues to be pursued to obtain a truly reliable cutting tool. In this study, using two inserts with initial A and B, the insert material has the same oxide element, Al2O3 + TiO2, but the composition is different. Insert A and B are produced in two different countries. The geometry of the insert is also the same as a triangle with a cutting angle of 600 degrees. Insert A with an oxide composition of 1.08% Al2O3 + 98.92% TiO2 with 87 HRC hardness while insert B with oxide composition 3.05% Al2O3 + 96.95% TiO2 with 79 HRC hardness. The purpose of this study was to determine the behavior of both types of inserts after being operated in AISI 301 stainless steel dry turning for 60 minutes. The research method is experimental by directly observing the condition of the two inserts which are operated alternately. The results showed that there was damage that occurred on both the insert or cutting tool in the form of crater wear and edge wear. Cutting parameters, oxide elements, composition, and hardness of the insert or cutting tool also affect the behavior or damage of the cutting tool. The largest edge wear occurs on the insert or cutting tool, insert A for, VB = 0.298 mm, and B for, VB = 0.323 mm. This shows that Insert A is of better quality than Insert B.
