9. Shearing Shearing is a sheet metal cutting operation along a straight line between two cut-ting edges by means of a power shear.

11. Bending Bending is defined as the straining of the sheet metal around a straight edge

13. Drawing Drawing is a sheet-metal operation to make hollow-shaped parts from a sheet blank

14. Equipments

15. Mechanical Press – The ram is actuated using a flywheel. Stroke motion is not uniform.

16. Hydraulic Press – Longer strokes than mechanical presses, and develop full force throughout the stroke. Stroke motion is of uniform speed, especially adapted to deep drawing operations

17. Dies and Punches Simple - single operation with a single stroke Compound - two operations with a single stroke Combination - two operations at two stations Progressive - two or more operations at two or more stations with each press stroke, creates what is called a strip development
