3axis CNC machining evolved from rotary filing (think dental drill 😬). With a 3axis CNC machine, the workpiece is stationary while the cutting tool moves across the X, Y, and Zaxes. The Xaxis (vertical axis) is left to right along the lathe table, the Yaxis (horizontal axis) is from front to back of the table, and the spindle that ...
