Jan 01, 2011· Milling is a complex process in which a rotating solid or multiple indexableinserts cutter removes metal or other material. Each insert removes a small amount of metal with each revolution of the spindle. Because the workpiece and cutter can be moved in more than one direction at the same time, surfaces with almost any orientation can be machined.

The end mill speed is calculated with the following formula n [rpm] = (vc [m/min] *1) / 3.14 * ø d1 [mm]) Example calculation vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.

Using multiple axes of a CNC machine allows you to helically interpolate the thread profile into a work piece. Unlike a tap, a thread mill has a smaller diameter than the thread size being produced because the mill must be able to enter into the drilled hole and interpolate. Thread milling provides excellent control of the threads major diameter

Mar 21, 2011· Ron Davis, Manager, Training and Development, WIDIA Products Group. In milling, cutting forces are exerted in three planes to deform and shear away material in the form of a chip. Tangential cutting forces overcome the resistance to rotation and account for 70 perent of the total force. Feed forces account for 20 percent of the total force.
