Which of the following are considered basic processes? (as opposed to secondary processes) (four correct answers): annealing anodizing drilling electroplating forward hot extrusion to produce aluminum bar stock impression die forging rolling of sheet steel sand casting sheet-metal stamping spot welding surface grinding of hardened steel tempering of martensitic steel turning

Solution

Among the given processes, the basic Processes are:

(e) Forward hot extrusion to produce aluminium bar stock

(f) Impression die forging

(h) Sand Casting

(m) Turning

Because all these processes are to be carried out before all other processes. Also these processes cannot be done after other process. That is why these processes are called Basic Processes.
