Which button is used to start or resume a CNC program?

• A. Pause
• B. Cycle Start
• C. Run
• D. Execute

Answer: (B)

The button used to start or resume a CNC program is the Cycle Start button. This button is a crucial part of CNC operation, as it initiates or continues the execution of the programmed instructions on the machine. When pressed, the Cycle Start button informs the CNC system that it should commence the machining process or pick up from a point where it may have been paused. This functionality is critical for maintaining operational efficiency and precision in producing components according to specified plans. In contrast, options like Pause, Run, and Execute may sound relevant, but they serve different purposes within the CNC operational context. The Pause button is used to temporarily halt the program, allowing the operator to make adjustments or check the machining without ending the cycle. The Run button might intuitively suggest operation, but it is not a standard designation used in most CNC interfaces—where Cycle Start is specifically recognized for initiating the cycle. Execute could imply carrying out commands, but it does not typically refer to the action of starting or resuming a CNC program and may not be labeled on all machines. Thus, the Cycle Start button is distinctly designed and universally understood within the CNC environment as the means to commence or resume machining operations.
