dE/dL = KL n (111) where dE is the differential energy required, dL is the change in a typical dimension, L is the magnitude of a typical length dimension and K, n, are constants Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L This implies that n in eqn (111) is ....

What is Deep Hole Drilling
A deep hole is defined by its depthtodiameter ratio (D:d), and typically holes greater than 10:1 are considered deep holes Deep hole drilling into metal has a range of applications across several industries, with its origins tracing back to the need for straighter, more accurate gun barrels, and expanding as other industries integrated deep hole drilling processes to improve their own ....
