INTRODUCTION
As the world is advancing forth technically in the field of space research, missile and nuclear industry; very complicated and precise components having some special requirements are demanded by these industries. For meeting these challenges unconventional methods of machining have evolved. The unconventional methods of machining have several specific advantages over conventional methods of machining and these promise formidable tasks to be undertaken and set a new record in the manufacturi ....etc

After WWII Japanese manufacturers were struggling to survive with very limited resources. If it were not for the advancements of Taguchi the country might not have stayed afloat let alone flourish as it has. Taguchi revolutionized the manufacturing process in Japan through cost savings. He understood, like many other engineers, that all manufacturing processes are affected by outside influences, noise. However, Taguchi realized methods of identifying those noise sources which have the greatest effects on product variability. His ideas have been ....etc

Abstract:
Many parameters affect the quality of the resistance spot welding (RSW) process. It is not easy to obtain optimal parameters of the RSW process in the automobile industry. Conventionally, the Taguchi method has been widely used in engineering; however, with this method the desired results can only be obtained with the use of very discrete control factors, thus leading to uncertainty about the real optimum. In the process ....etc

Spot welding by automation System



. ROBOT & THE CONTROLLER

The robot is typically comprised of a large number of
links and linkages, which are interconnected by gears,
chains, belts & screws .

The majority of industrial robots
are actuated by linear, pneumatic, hydraulic actuators
or electric Drives(AC/DC motors).

In an arc welding robot system, the torch is attached
to the wrist ....etc

Introduction
The use of high-power near-infrared diodelasers for joining plastics is growing.More development work is being performedin institutions and in R&D labs,and applications in industry are slowlyincreasing. Several different approachesare being developed for laser welding ofplastics. The main principle now used tolaser-weld plastics is known as “transmissionwelding.” Transmission welding hasdemonstrated that precise, controllableheating and melting of low melting pointthermoplastics can be produced at the interfacebetween ....etc
