All machines exist to decrease human effort and make our lives easier.
Most devices around us rely on human decision-making. For example, traditional drilling equipment must be stopped after drilling. This machine can't tell if a hole is drilled or not. Other machines are the same.
These devices have a fundamental flaw: operator mistakes. Humans have various flaws, such as fatigue, emotions, and an inherent predisposition to make mistakes.
All of this prompted engineers to create machines that can accomplish tasks without human interaction. These devices should also be precise and avoid any mishaps. So the necessity for CNC machines arose.
What is a CNC?
CNC means computer numerical control. In this case, a numerical program controls both the tool and the workpiece.
CAD and CAM are essential to CNC machining.
ACAD is a Computer-Aided Design, whereas CAM is a Computer-Aided Manufacturing. With CAD, we create a 3-D model of the product we want to build, and with CAM, we make it real.
Modern CNC machines are incredibly accurate and may substantially cut the production time.
