For a 4.8-mm threadmillused to create an M6 x 1 thread, the feedrateat the edge of the tool is 238 mm/min. Conversely, the feedrateat the center of that tool is only 47 mm/min. Moving the tool too slowly leads to extended machining time (five times longer in this example).
Nov 01, 2015· The milling test conditions were carried out with a ballfillingof J T = 20%, a powderfillingof U T = 0.75, amillspeed ϕ cT = 75% of critical speed and feed size of (− 850 + 600 μm). The remaining set of parameters was back-calculated within the population balance model framework.
Mill RatesAmillis equal to $1.00 of tax for each $1,000 of assessment. To calculate the property tax, multiply the assessment of the property by themill rateand divide by 1,000. For example, a property with an assessed value of $50,000 located in a municipality with amill rateof 20 mills would have a property tax bill of $1,000 per year.

Grain yield in corn (Zea mays L.) is a function of therateand duration of dry matter accumulation in the grain.We developed a technique for calculating these two components, based upon a regression analysis of yield over time. At least 90% of the grain accumulated linearly beginning 2½ weeks after silking.
Early-maturing maize (Zea mays L.) genotypes yield 15 to 30% less than late-maturing genotypes.
