Types of milling operationAS PRECISION
Side Milling. The side milling is the production of a flat vertical surface on the side of a work piece by using a side-milling cutter. The depth of cut is adjusted by rotating the vertical feed screw of the table. Straddle Milling. When two or more parallel vertical surfaces are machined at a single cut the operation is called straddle milling.
