In this paper, numerical investigation of the effects of microgroove textured cutting tools in high speed machining of AISI 1045 is conducted using Finite Element Method (FEM). Microgrooves are designed and fabricated on the rake face of cemented carbide (WC/Co) cutting inserts. The effects of microgroove width, edge distance (the distance from cutting edge to the first microgroove), and microgroove depth are examined and assessed in terms of main cutting force, thrust force, and tool-chip contact length. It is found that microgrooved cutting tools generate lower cutting force and consequently lower the energy necessary for machining. This research provides insightful guidance for optimizing tool life and reducing energy consumption in high-speed machining of AISI 1045 steel.
