Effects of Cutting Parameters on the Cutting Force and Torque in Drilling of AISI D2 Steel
Journal Title: Machine Design - Year 2017, Vol 9, Issue 1
Abstract
Drilling is an important machining procedure. Knowing the best work piece-cutting tool match and the ideal cutting parameters would improve the machining quality especially to overcome challenges faced during the machining of newly developed materials. In the experimental studies, AISI D2 steel is drilled by using 14 mm coated and uncoated solid carbide drills (AICrN) at four cutting speeds (60, 75, 90 and 108 m/min) and three feed rates (0.15, 0.20 and 0.25 mm/rev). The effects of cutting speed, feed rate and coating on the thrust force, cutting force and torque are investigated. According to experimental results, increasing feed rate caused an increase in thrust force and torque in all tests, performed using coated and uncoated drills. Increasing cutting rate decreases torque with uncoated drills while it increases the thrust force. On the other hand, increasing cutting speed with coated drills decreases thrust force and torque. It is observed that feed rate, cutting speed and drill type are the most important parameters in drilling. Best results were obtained at 60 m/min cutting speed and 0.15 mm/rev feed rate for uncoated drills and 108 m/min cutting speed and 0.15 mm/rev feed rate for coated drills.
