Which of the following commands is used for changing to a different plane?

• A. G20
• B. G21
• C. G17
• D. G19

Answer: (D)

The command that is used to change to a different plane in CNC programming is G19. This command specifically selects the YZ plane for machining. Understanding the use of G-codes in CNC operations is crucial for effectively controlling the machine and executing precise movements. Each G-code serves a specific purpose, with G17 selecting the XY plane, G19 selecting the YZ plane, and G18 selecting the XZ plane. As such, G19 is the correct choice for those situations where operations or tool paths need to be executed in the YZ orientation. This command ensures that the tool can access the material in the specified plane, allowing for appropriate programming of 3D objects and complex shapes within that orientation. Knowing which plane you are operating in is critical for maintaining accuracy in machining and ensuring that the part geometry is produced as intended.
