Analysing the impact of cutting parameters of CNC machining on EN8 steel with high strength carbide tool tip insert

Turning is an often observed technique in the field of metal cutting. During CNC machining, a work material is rotated along its axis while cutting tools at the centre of its axis are used to remove excess material and create the desired component. The ultimate level of quality and accuracy of the end result depends on several factors. In this context, three crucial parameters stand out as key contributors: cutting speed, feed rate, and depth of cut. The specific input parameter chosen for the working material is EN 8, and the cutting tool used is a carbide insert. Observation of tool wear can be made by examining the effects of velocity, feed rate, and cutting depth under different conditions. EN8 steel is a type of steel that has a significant amount of carbon and has a stiffness of around 600 MPa. The displayed graphs obtained from the conducted CNC machining process research provide clear insights into the patterns that demonstrate how the progression of tool flank wear ultimately results in failure. Through the implementation of several experiments, we successfully examined the influence of input variables on both the Material Removal Rate and Tool Wear.
