Abstract

Drilling is an indispensable machining method for many industrial products and involves a difficult the cutting mechanism due to the complexity of the chip formation process. For this reason, it is required a long and costly process to examine in detail the interactions between the machining outputs such as surface quality, cutting force, tool life, amount of energy consumed and the cutting tool-material pair technical specification, cutting parameters and cutting environment. In this context, it is possible to estimate machining outputs by making cutting simulations based on the finite element method to contribute to sustainable manufacturing. In this study, the drillability of the AISI 420 stainless steel was investigated by drilling simulations in the ThirdWave Advantages software. Drilling operations were performed with uncoated carbide drill at three different cutting speeds (40, 60, 80 m/min) and feed rate (0.1, 0.2, 0.3 mm/rev). In drilling of the stainless steel, the effects of the drilling parameters on the thrust force, torque and temperature were analyzed. As a result of the evaluations, it was determined that the values of thrust force and torque increases as the cutting and feed speed increases. In the optimization of drilling parameters, it has been shown that the finite element method can be used as an important tool.
