Conventional milling (or up milling) is a milling process in which the cutting tool rotates in the same direction as the workpiece's motion, so the tool moves in the opposite direction to the material feed. It is more applicable to higher ductility materials and allows faster machining. This results in progressive cutter engagement, increased ...

In the milling process, rigidity and tool vibrations are significant issues to take into account. The characteristic features of the milling process, such as intermittent cutting, machining area, high spindle speed, cause more cutting vibration to be produced.

Flow diagram of wet milling process of maize is illustrated in Fig. 5.2. Wet milling of maize involves steeping of maize in water for 30–40 h at 50 °C in the presence of SO 2 (0.02 %) to soften the kernels. SO 2 prevents fermentation and facilitates the separation of starch from protein. After steeping, the steep water is drained, and grains ...

Milling. Cereal processing is complex. The principal procedure is milling—that is, the grinding of the grain so that it can be easily cooked and rendered into an attractive foodstuff.
