01/05/2012  When the required machining power value is about the same as the milling machine’s rated power, milling productivity approaches its maximum. Torque (T s) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t) and can be calculated by the formula: T s = F t × R (1)

When cutting metal on a CNC milling machine, the force required for the tool to cut into the workpiece to deform the workpiece material into chips is called the cutting force. Cutting force is an important basis for calculating cutting power, designing tools, machine tools and machine tool fixtures, and formulating cutting parameters. In automated production, the cutting force can also be used to monitor the cutting

01/05/2012  The engagement factor of a workpiece material (E f) is a dimensionless coefficient included in formula (2) to correlate tangential cutting force with the ratio of the radial WOC to the cutter diameter (W ÷ D). Milling is more effective when sufficiently thick and uniform chips are produced. The W/D ratio affects uniformity of the chip thickness. When the radial WOC equals the cutter diameter (W ÷ D = 1),

Milling Machine: Definition, Parts, Operation,

The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter. The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
