Which axes are typically controlled in the machine setup of a CNC system?

  1. X and Y axes only

  2. X, Y, and Z axes

  3. Only the Z axis

  4. Only the X axis

The correct answer is: X, Y, and Z axes

In a CNC system, the typical machine setup involves controlling the X, Y, and Z axes to achieve precise and accurate machining operations. The X and Y axes generally represent the horizontal plane, allowing for movement in two-dimensional space, while the Z axis typically represents vertical movement, enabling depth adjustments. Controlling all three axes is essential for complex machining tasks, such as milling, where the cutter needs to navigate through a three-dimensional space to create detailed shapes and features. This multi-axis control allows for the machining of intricate geometries that would not be possible with only one or two axes. Thus, the selection of X, Y, and Z axes reflects the fundamental capabilities necessary for a broad range of CNC operations, making it the correct answer.
