Which process involves removing material using a rotary cutter?

The correct answer is milling, which is a machining process that involves removing material from a workpiece using a rotary cutter. In milling, the rotary cutter rotates while moving across the material, effectively cutting away unwanted sections to achieve the desired shape and dimensional specifications. This process is highly versatile and can produce complex geometries, making it essential in various manufacturing applications.

Milling differs from other processes like drilling, which primarily creates holes in a material rather than shaping it through the removal of material across a wider area. Grinding, on the other hand, typically uses an abrasive wheel to refine surface finishes or remove small amounts of material, rather than employing a rotary cutter to shape the workpiece. Turning is a process that involves rotating the workpiece around a fixed axis while a cutting tool removes material to shape cylindrical parts.

Milling is essential in terms of precision and the ability to create intricate features in parts, showcasing its importance in the field of Computer Integrated Manufacturing.
