Rolling (metalworking) - Wikipedia
Flat rolling is the most basic form of rolling with the starting and ending material having a rectangular cross-section. The material is fed in between two rollers, called working rolls, that rotate in opposite directions. The gap between the two rolls is less than the thickness of the starting material, which causes it to deform. The decrease in material thickness causes the material to ...

Figure BI-6: Development paths for today’s drill bits.
Roller-cone bits There are three basic design factors for roller-cone bits: • Cone offset; • Journal (bearing pin) angle; • Cone profile. Offset The bit cone’s “offset” is defined as the horizontal distance between the axis of the bit and a vertical plane through the axis of the journal. Offset is established by moving the centerline of a cone away from the centerline of the bit in ...
