• ### MILLING DYNAMICS

MILLING DYNAMICS. Milling is, of course, a machining operation. In fact, in colloquial use, “to machine” often means to mill a particular workpiece. More than that, milling is a mechanical machining operation, as opposed to, say, electrochemical machining. As such, certain mechanical principles that have to with chip formation, cutter geometries, horsepower requirements, and the like apply

• ### Milling (machining) Wikipedia

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
