    The rolling process is best defined as the shaping of metals into semifinished or finished forms by passing between rollers rotating in opposite direction Just like any other metal forming process, rolling works in the same way The deformation takes place when a compressive force is applied by a set of rolls on ingot or any other product like billets, blooms, sheets, slabs, plates,01/09/2017· Machining a metal surface leaves microscopic peaks and valleys that are called roughness Surface finishing, whatever the method, is about reducing the roughness average (Ra) value of the surface Basically, the Ra value is a formula that measures the average distance between the tops and bottoms of these points relative to the mean line, which cuts throughWhat Is Roller Burnishing? | Modern Machine ShopHot rolling is a metalworking process that occurs above the recrystallization temperature of the material After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardeningThe starting material is usually large pieces of metal, like semifinished casting products, such as ingots, slabs,Rolling (metalworking) Wikipedia
