In machining operations, the effects of high temperatures are i) reduction in tool life, ii) production of hot chips and iii) inaccuracies in workpiece dimensions. Coolant is applied to convey away heat to extend tool life and ensure a good surface finish of the workpiece. While conventional...

Production by pressing in its many forms together with sheet metal working constitutes one of the most absorbing branches of production engineering, and one which plays a vital role in domestic life, being largely responsible for many of the comforts which have been brought within the reach of...

All sheet metal forming processes occur after permanent plastic deformation resulting in the material properties changing and therefore it is necessary to determine the extent to which a material can further be deformed for subsequent forming operations. Traditionally, experimental trial and...
