MILLING. The Spanish operated a few crude mills at Texas missions, but the first American settlers in Texas manufactured meal by pounding corn with a wooden pestle in a mortar hollowed out of a log or stump as the Indians had done. By 1826 there were several mills in Texas, operated by hand or powered by horses or mules.

Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

Milling is a crucial step in post-production of rice. The basic objective of a rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently milled and free of impurities. Depending on the requirements of the customer, the rice should have a minimum number of broken kernels.
