METAL SHAPING

There are only five operattions to shape the metal:

 CUT
  PICK
 STRETCHING
 WELD
 FOLD

The metal shaping is the way to shape in cold the metal.
one of the metalworcking tool is the english weel, that enables a craftsman to form compound (double curvature) curves from flat sheets of metal such as aluminium or steel. The process of using an English wheel is known as Wheeling. Panels produced this way are expensive, due to the highly skilled and labour intensive production method, but it has the key advantage that it can flexibly produce different panels using the same machine. It is a forming machine that works by surface stretching and is related in action to panel beating processes. It is used wherever low volumes of compound curved panels are required; typically in coachbuilding, car restoration, spaceframe chassis racing cars that meet regulations that require sheetmetal panels resembling mass production vehicles (Nascar), car prototypes and aircraft skin components. English wheel production is at its highest volumes, in low volume sports car production, particularly when more easily formed aluminium is used. Where high volume production runs of panels are required the wheel is replaced by a stamping press, that has a much higher capital set up cost and longer development time than an English Wheel, but each panel in the production run can be produced in a matter of seconds. This cost is defrayed across a larger production run, but a stamping press is limited to only one model of panel per set of dies. The English wheel model shown is manually operated.
