Machining 101: What is Five-Axis Machining? | Modern Machine Shop

Jul 31, 2021For example, the surface speed of a ball mill depends on the contact angle between tool and surface. On three-axis equipment, this angle changes as machining proceeds. When the bottom of the ball mill contacts the part, surface speed becomes an unproductive zero. Surface speed then reaches its peak when the tool's equator contacts the part.
