Feb 03, 2017 Feed the workpiece in a direction opposite the rotation of the milling cutter (conventional milling). Do not change feeds or speeds while the milling machine is in operation. When using clamps to secure a workpiece, be sure that they are tight and that the piece is held so it will not spring or vibrate under cut. Use a recommended cutting oil liberally. Use good judgment and common sense in

PLANER MACHINES. Presented By: Josell L. Caipang Richard E. Lagata What is a planer ? A planer is a type of metalworking machine tool that is some what similar to a shaper, but larger, and with the entire workpiece moving beneath the cutter, instead of the cutter moving above a stationary workpiece. The work table is moved back and forth on the bed beneath the cutting head either by mechanical
