CNC Cutting Machine Practice Test

In CNC machining, what does the term "tool movement" refer to?

1. The tool moves relative to the component

2. The tool remains stationary

3. The component moves relative to a fixed tool

4. The tool moves in random directions

The correct answer is: The tool moves relative to the component

The term "tool movement" in CNC machining specifically refers to the way the tool interacts with the workpiece by adjusting its position and path to achieve the desired cut or operation. When the tool moves relative to the component, it indicates that the tool travels over the surface of the component, removing material in a controlled and precise manner as dictated by the CNC program. This precision is critical in ensuring that the workpiece maintains tolerances and achieves the desired final dimensions. The focus on relative movement emphasizes the role of the tool in executing complex patterns and shapes based on the programmed instructions, while the position and stability of the component are usually fixed during the machining process. The other choices describe alternatives that do not align with the fundamental principles of CNC machining.
