CNC machining steel presents challenges such as tool wear due to hardness, heat generation requiring effective cooling, and variable machinability across steel alloys. Work hardening during machining and managing sharp chips add complexity. Achieving a smooth surface finish and addressing dimensional stability amid residual stresses are critical. Optimal tool selection, considering steel abrasiveness, and maintaining machine rigidity are essential for successful CNC machining of steel. Overcoming these challenges relies on skilled programming, experience, and adapting strategies based on the specific steel alloy being processed.
