Tangent of a Circle Calculator

A tangent intersects a circle in exactly one place It is a line which touches a circle or ellipse at just one point The square of the length of tangent segment equals to the difference of the square of length of the radius and square of the distance between circle center...

Circular Sawmills and Their Efficient Operation

some variation between boards All mills must Include a plus or minus tolerance around their target set to allow for this variation in lumber thickness The amount of tolerance required for a given sawmill depends upon stress in the logs condition of mill...

Drill And Bore With A Face Mill Modern Machine Shop

Mr Turner says he could use an end mill drop down to a Z value run around the circle and repeat that until he gets to depth which is the conventional hole milling technique Using the face mill the depth of feed cannot exceed the height of the insert and therefore most...

G02 CW / G03 CCW Circular Interpolation Motion Group 01

These G codes are used to specify circular motion Two axes are necessary to complete circular motion and the correct plane G17-G19 must be used There are two methods of commanding a G02 or G03 the first is using the I J K addresses and the second is using the R address...

A milliradian SI-symbol mrad sometimes also abbreviated mil is an SI derived unit for angular measurement which is defined as a thousandth of a radian 0 001 radian Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel up down left or right Milliradians are also used for...

There are 2 PI radians in a circle PI is a constant of approximately 3 1416 That is 2 3 1416 or 6 283 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 17 78 mils equal 1...
