non traditional machining notes 6th sem mechanical vtu notes pdf

When people hear the word machining they generally think of machines that utilize mechanical energy to remove material from the work piece. Milling machines, saws and lathes are some of the most common machines using mechanical energy to remove material. The tool makes contact with the work piece and the resulting shear causes the material to flow over the tool. All traditional forms of metal cutting use shear as the primary method of material removal. However, there are other ....etc
