Abstract

The paper gave a detailed definition of jigs and fixtures, and also identified the numerous advantages that are associated with the use of jigs and fixtures in manufacturing to include: production increase, cost reduction, interchangeability and high accuracy of parts, reduction of the need for inspection and quality control expenses, reduction of accident as safety is improved, automation of machine tool to an appreciable extent, easy machining of complex and heavy components, as well as low variability in dimension which leads to consistent quality of manufactured products. The work also explained that since the design is dependent on numerous factors which are analyzed to achieve an optimum output, that jigs and fixtures should be made of rigid light materials to facilitate easy handling. For adequate strength and rigidity, a mild steel with 16 millimeters diameter was chosen for the design of a sample jig and fixture. Mild steel which contain about 0.29% of carbon are very cheap, and because of their easy availability are often the choicest material for the making of jigs of fixtures.With 1.5 as the material factor ‘k’ for mild steel, a feed rate of 0.17 millimeter per revolution, and a drill diameter of 16 millimeters, the Thrust/Drilling force was calculated as 3094.2 N. The Force acting on each of the lips was calculated as 1700 N, the Torque (M) was gotten as 1360N-mm, while the value of the Clamping Force was also calculated as 4080N. The calculated values confirmed that a 16 millimeter diameter mild will lead to the construction of a rigid and strong jigs and fixtures that will guarantee high machining accuracy, consistent quality of products, and interchangeability. Finall, the paper advocated that jigs and fixtures must be provided with adequate clearance which should allow for variations in size of components especially during forging, milling, and casting operations.
