【正文】 ling is essential to fabricate any object that is not axially symmetric. There is a wide range of different milling machines, ranging from manual lightduty Bridgeports226。 to huge CNC machines for milling parts hundreds of feet long. Below is illustrated the process at the cutting area.Milling: ColumnandKnee Manual MillBelow is illustrated a typical columnandknee type manual mill. Such manual mills are mon in job shops that specialize in parts that are low volume and quickly fabricated. Such job shops are often termed model shops because of the prototyping nature of the work.The parts of the manual mill are separated below. The knee moves up and down the column on guideways in the column. The table can move in x and y on the knee, and the milling head can move up and down.Grinding: IntroductionGrinding is a finishing process used to improve surface finish, abrade hard materials, and tighten the tolerance on flat and cylindrical surfaces by removing a small amount of material. Information in this section is organized according to the subcategory links in the menu bar to the left.In grinding, an abrasive material rubs against the metal part and removes tiny pieces of material. The abrasive material is typically on the surface of a wheel or belt and abrades material in a way similar to sanding. On a microscopic scale, the chip formation in grinding is the same as that found in other machining processes. The abrasive action of grinding generates excessive heat so that flooding of the cuttin
