Manufacturing Influence Area After Heat Treatment

The machining of hardened components with a hardness of at least 47 HRC is referred to as hard machining [1]. The most well-known hard machining processes are grinding, hard turning, hard drilling, hard milling, and wire and sinker EDM. Detailed explanations about the cutting hard machining processes can also be found in [1]. Wire and sinker EDM is very often used in toolmaking [2].
