What is a 'part program' in CNC machining?

• A. A type of cutting tool used in milling
• B. A series of digitized instructions for the CNC machine
• C. A manual describing machine operations
• D. A measurement of machining speed

Answer: (B)

A 'part program' in CNC machining refers specifically to a series of digitized instructions that guide the CNC machine on how to perform its tasks. This program essentially provides the machine with step-by-step commands that define the movements, speeds, and other parameters necessary for shaping a workpiece accurately and efficiently. It includes details about where to move, how fast to cut, and the operational sequence, ensuring the desired geometry and quality of the finished part. This understanding highlights the critical role of part programs in the CNC machining process, as they serve as the blueprint that dictates the entire operation of the machine. The precise nature of these instructions allows the machine to execute complex tasks with great accuracy and repeatability, which is a hallmark of CNC technology.
