A rule of thumb is 0.010 " to 0.015 " should remain after drilling for reaming, except for small diameters, such as 1⁄32 ", which should have 0.003 " to 0.006 " of material for reaming, Lynberg noted.Hard Rock Miner's Handbook,Long before science and engineering evolved, Rules of Thumb constituted the sole body of mining knowledge. In 1891, the Royal Commission on mineral resources in Ontario, Canada stated that we had been “mining by rules of thumb for long enough.” The Royal Commission probably never imagined that over 100 years later we not only continue to employMoore's law - Wikipedia,Moore's law is the observation that the number of transistors in a dense integrated circuit (IC) doubles about every two years. Moore's law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production.. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and,

Thumb ruleScale economies and the “0.6 rule” - ScienceDirect,One aspect of scale economies which has received more attention in the engineering than in the economics literature is the “0.6 rule”. This rule has its origins in the relationship between the increase in equipment cost (C) and the increase in capacity (V) given by C 1 /C 2 = (V 1 /V 2) α where α denotes the scale coefficient.A value of α less than unity implies increasing returns to scale.Breaking Chips and Controlling Burrs when Machining,,Jul 24, 2015· The old school rule of thumb is that the depth of cut per side should never be less than 66 percent of the nose radius because, at that point, all chip thinning (which is a function of the size of the nose radius and depth of cut) stops.
