Workshop Math

Workshop technology is the application of scientific principles and methodologies for the manufacturing of machine components, tools, dies, etc. Workshop technology also provides the techniques, which can be carried out for metal joining and cutting processes. In a nutshell, workshop technology deals with metal works, and in a few cases, processing with plastics is also carried out. A mechanical workshop has seven major departments, each of the departments has sophisticated equipment and tools to carry out the manufacturing process. The major departments of mechanical workshops are plumbing shops, machining shops, carpentry shops, fitting shops, sheet metal shops, casting and foundry shops, and welding shops.
