D2 steel is an industrial tool steel. It is widely used in the tool and die industry for making cutting tool inserts, bending inserts, restriking inserts, etc. which can be taken out after their tool life. D2 steel is a very tough steel and difficult to machine also. High generations tool bits like Tungsten carbides and Titanium carbides are required to machine them. The heat treatment follows the machining process. Their machinability is very low. CNC machines are often used to finish them. Often they are machined using programs on UG-NX Uni Graphics(CAM) and DELCAM. And they have to be machined in three steps. Roughing operations, followed by Semi-Finish machining and the last step is finish machining.CNC machining centers are versatile in their applications in metal removal processes. Often they are so modernized that just like many manufacturing operations, metal removal can be automated too. The need for CNC machining arises due to extensive finishing requirements in the aerospace, automotive industries. However, the CNC or Computer and Numerically controlled machining process usage is not limited to these industries only. Tool and Die industry also is heavily dependent on CNC material removal and machining processes as now replaceable inserts are widely used in this industry.
