WhatsApp: +86 18203695377Milling says : Avoid interrupted cuts. An interrupted cut is one where the tool alternately enters and leaves the workpiece during the cut. Because cast iron has relatively low tensile strength, the tendency of the cutting forces it to break out the edge of the casting as the tool leaves the work.
