EATHU Case Study on Precision Machining
The article details how surface roughness, with its range of evaluation metrics and various measurement methods, determines the performance of a part in terms of friction, wear, and fatigue; how surface hardness, with its range of reinforcement techniques, resists wear and compression; and how surface finish, with its range of polishing and grinding methods, combines aesthetics with functionality. Rigorous surface requirements, machining challenges, and solution strategies are analyzed through real-world examples of aero-engine blades and automotive engine pistons.
