On a CNC (Computer Numerical Control) machine, the direction of the Z-axis depends on the specific machine's configuration and setup. However, in the commonly used Cartesian coordinate system, which is prevalent in CNC machines, the Z-axis generally represents the vertical axis.
In this system, the X-axis typically represents the horizontal movement from left to right, the Y-axis represents the horizontal movement from front to back, and the Z-axis represents the vertical movement, typically up and down. This setup allows the CNC machine to move and position the cutting tool or workpiece in three dimensions, enabling it to perform various machining operations accurately.
However, it's essential to note that the orientation of the axes may vary depending on the machine and the coordinate system used. It's always a good practice to consult the machine's documentation or manufacturer's specifications to determine the specific orientation of the axes for a particular CNC machine.
