Basic Milling Operations Before any milling job—no matter how simple—is attempted, the machinist has to make several decisions. In addition to selecting the best means of holding the works and the most appropriate cutters, the machinist must make an initial estimate of the cutting speed and feed rate that will provide good balance between rapid metal removal and long cutter life. Cutting

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, heavyduty gang milling operations.

Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.. In a milling machine, the cutter is rotating due to this workpiece is fed against can hold more than one tool at a time. The cutter rotates at a high speed and because of the many cutting edges, it removes metal at a very fast rate.

Milling Machine Operations Page 27 of 37 To get optimum use for a cutter, the proper speed at which the cutter should be revolved must be determined. When machining mild steel, a high speed cutter would have to achieve a surface speed of about 90 ft/min. Since the diameter of the cutter affects this speed, it is necessary to consider the diameter in the calculation. The following example
