Peck milling. Opening a slot. When milling a hole, linear ramping (2-axes simultaneously) is always preferred to peck milling. Peck milling is an alternative hole milling method, but it often produces long chips and generates undesirable cutting forces on the cutter. Opening a hole or a cavity. Drilling. Read More
