MODULE 5 SHEET METAL OPERATIONS

Sheet bending Sheet bending is defined as the straining of the metal around a straight axis. During bending operation, the metal on the inner side of the neutral plane is compressed, and the metal on the outer side of the neutral plane is stretched. Bending causes no change in the thickness of the sheet metal.

FORGING

Roll forging In this process, the bar stock is reduced in cross-section or undergoes change in cross-section when it is passed through apair of grooved rolls made of die steel. This process serves as the initial processing step for forging of parts such as connecting rod, crank shaft etc.

MULTI-STAGE VAPOUR COMPRESSION REFRIGERATION …

•A multi-stage system is a refrigeration system with two or more low-side pressures. •Multi-stage systems can be classified into: a) Multi-compression systems b) Multi-evaporator systems c) Cascade systems, etc. •Two concepts which are normally integral to multi-pressure systems are, i) flash gas removal, and ii) intercooling.

Carbon and Low Alloy Steel Casting Mechanical Properties

Carbon content and heat treatment influence strength and ductility; shown in Figure 1. Carbon contents are typically kept well below 0.30% to avoid problems with cracks in heat treating or welding. The relationship between the ratio of stress to strain is the elastic modulus. Data is derived from a tensile test. The
