2、and Cutting TechnologyShunmugam MBasic Machining OperationsMachine was developed from the early Egyptian pedal car and John Wilkinson's trampoline. They provide rigid support for workpieces and tools and can precisel

3、y control their relative position and relative speed. Basically, metal cutting refers to a sharpened pry tool that removes a very narrow metal from the surface of a tough workpiece. Chips are discarded products. Compared

4、 with other workpieces, the chips are shorter, but there is a certain increase in the thickness of the uncut parts. The geometry of the workpiece surface depends on the shape of the tool and the path of the tool during m

5、achining operations.Most machining processes produce parts of different geometries. If a rough workpiece rotates on the central axis and the tool cuts into the workpiece surface parallel to the center of rotation, a rota

6、ting surface is created. This operation is called turning. If a hollow tube is machined on Basic machineThe machine tool produces parts with special geometry and precise dimensions by removing chips from plastic material

7、. The latter is waste, which is a change from the long continuous strip of plastic material such as steel, which is useless from a processing point of view. It is easy to handle cracked chips produced from cast iron. The

8、 machine performs five basic metal removal processes: turning, planing, drilling, and milling. All other metal removal processes are modified from these five basic procedures. For example, boring is internal turning; rea

9、ming, tapping and counterboring are further machining of drilled holes; gear machining is based on Milling operation. Polishing and sanding are deformations that grind and remove the abrasive process. Therefore, there ar

10、e only four basic types of machine tools that use specially controllable cutting tools: 1. Lathes, 2. Drilling machines, 3. Milling machines, 4. Grinding machines. The grinding process forms chips, but the geometry of th

11、e abrasive particles is uncontrollable.The amount and speed of material removal through various processing steps is enormous, just as high facets are removed in large turning operations, or in extremely small grinding an
