Vertical Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Vertical machining occurs on a vertical machining center (VMC ), which employs a spindle with a vertical orientation. With a vertically oriented spindle, tools stick straight down from the tool holder, and often cut across the top
