What is the term for the series of instructions a CNC machine follows to process a workpiece?

• A. CNC Code
• B. Part Program
• C. Tool Path
• D. Feed Rate

Answer: (B)

The series of instructions that a CNC machine follows to process a workpiece is referred to as a part program. This part program includes the precise commands and parameters that dictate how the machine should operate, including movements, speeds, and tool usages. It encompasses everything necessary for the machine to execute the desired machining operation on a workpiece, ensuring accuracy and consistency in production. While CNC code is related, as it often comprises the commands written in a specific programming language (like G-code), the term "part program" encompasses the entire set of instructions, which may include CNC code and other necessary operational parameters. Tool path specifically refers to the path that the tool will take during the machining process, while feed rate pertains to the speed at which the tool engages with the material, and these concepts are components of the overall part program but do not encapsulate the entire series of instructions.
