In the world of mechanical engineering and CNC machining, precision is paramount. However, not every dimension on a technical drawing requires a tight, specific tolerance. Over-dimensioning a part can lead to skyrocketing production costs and unnecessary inspection time. This is where becomes the silent hero of the workshop.
