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.

UPMILLING. The safest way to machine a piece of metal using a horizontal miller is to feed the metal into the cutter, against its rotation. This is called upmilling and it is the technique used in school workshops. The metal must be held very firmly in a large machine vice, usually a nylon or leather mallet is used to hammer round the handle of the vice to ensure it is extremely tight

Metal slitting saw milling cutters are used to part stock on a milling machine. Figure 839 illustrates parting solid stock. The workpiece is being fed against the rotation of the cutter. For greater rigidity while parting thin material such as sheet metal, the workpiece may be clamped directly to the table with the line of cut over one of the table Tslots. In this case, the workpiece should

If machines are operated under extremely dusty conditions. operate at the slowest speeds to avoid rapid abrasive wear on the moving parts and lubricate the machines more often. Under extreme cold conditions, start the machines at a slow speed and allow the parts and lubricants to warm up before increasing the speeds. Metal becomes very brittle in extreme cold. so do not strike the machines
