### difference between circle and mill

Degrees, Mils, Grads compass measurements, There are 2 PI radians in a circle PI is a constant of approximately 31416 That is 2 * 31416, or 6283 radians Divide each radian into 1000 mil-radians and you see there are 6283 mil-radians in a circle Mil-radians are called mils for short 1778 mils equal 1 degree Compass use of mils typically rounds 6283 to 6400 for simplificationThe Truth About Mil Dots, While we are distinguishing between Army and USMC reticles, I feel it is prudent to mention another difference Not only are the mils themselves different but the value of the dots is also different Army dots while commonly called ¾ mil dots are in reality ¾ moa dots (or 22 mil) This is to say that 1 dot subtends (covers) three quarters of ,Mill Levy Definition, The mill levy is a property tax applied based on the assessed value of the property The rate of the tax is expressed in mills - one mill is equal to one dollar per \$1,000 of assessed valueBolt circle calculator, Apr 12, 2015· The diameter of the holes that are equally distributed around the bolt circle diameter Bolt circle diameter: the diameter of the circle on which the holes will be evenly distributed Start angle: The 0° angle is to the right in the "X" axis and aligned with the center of the bolt circle in the "Y" axisIndexing: Meaning and Methods | Milling | Industries ,, The operation of rotating the job through a required angle between two successive cuts is termed as indexing This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine It helps to divide the job periphery into a number of equal divisions, ie, square, hexagonal octagonal, etc.
