CNC Cutting Machine Practice Test

Which of these processes is NOT a conventional NC machining process?

1. Drilling and boring

2. Milling

3. Shaping

4. Turning

The correct answer is: Shaping

Shaping is the correct choice for a process that is not considered a conventional NC (Numerical Control) machining method. While shaping involves the cutting of materials using a tool that moves back and forth across the workpiece, it is categorized more specifically under traditional machining processes. Conventional NC processes typically include operations that are commonly controlled by numerical data, such as drilling, boring, milling, and turning. Conventional NC machining processes, like drilling, boring, milling, and turning, utilize various CNC (Computer Numerical Control) technologies to achieve high precision and automation. Each of these processes is recognized for its ability to produce complex geometries and high-quality finishes consistently. In contrast, shaping, though it can be controlled numerically, is not commonly classified as a conventional NC machining process. It represents an earlier stage of machining technology and is often overshadowed by the advancement and automation of milling and turning techniques that are standard in modern CNC applications. Therefore, the distinction lies in the technological evolution and classification of these processes within the realm of numerical control machining.
