English to French Tech/Engineering Engineering (general) bloom and ingot manufacturing

contexte
"components have been manufactured using conventional manufacturing process where continuously cast (concast) bloom or cast ingot is subjected to forging process which results into forged bars followed by proof machining, heat treatment and final machining."

"One other object of the invention is to provide a near-net shape forging process for manufacturing of hollow shafts so as to enhance utilisation of material from the forging to proof machining stages of manufacturing. "

"Proof-machining (OD turning, finishing, and facing; boring and counter boring) to produce the final shaped hollow shaft."

"The heat treated component is proof-machined using suitable machining equipment and followed by stress relieving Stress relieving process helps to eliminate the stresses induced during proof machining."
