dc.description.abstractMetal forming is a production technique which enhances economic use of engineering materials by minimizing metal wastage that occurs in machining processes such as lathe turning and milling. This technique employs a press tool for mass production of parts that are dimensionally compatible.The press tool comprises the section that provides the force- the press, and the tooling section- the die. Investigation of stretch-forming conditions to produce a simple dome in order to determine the optimum condition of punch nose radius, die corner radius is established. This relationship provides a basis for determining forces, clearance, travel and profile of the die, thereby eliminating the trial and error method of tool design and of finding punch force. A tool of simple design and easy to maintain is developed for use in a press machine. A 60 KN, non-geared, open-fronted eccentric press with straight box frames, and with flywheel mounted on the shaft and operating at 90 strokes per minute is developed. The fundamental requirements of a press include a frame of adequate rigidity and strength to reduce deflection and absorb shock of stamping, appropriate flywheel energy and torque capacity to form parts in the tooling.The principle adopted for developing a transmission system which harnesses the power of the electric motor through the flywheel, clutch unit, shaft and connecting rod to the tooling is presented.en_US
