Plain milling, or slab milling, is a core milling process where a horizontal milling cutter machines flat surfaces on the workpiece. The cutter’s direction of rotation aligns with the feed direction in plain milling. In other words, the tool axis is parallel to the cut surface.
Generally, plain milling is quite useful for roughing cycles at the beginning of a manufacturing plan. It is effective in converting rough material stocks to fine prismatic, square geometries with accurate dimensions and smooth finishes, ready for further milling operations.
