VERNIER CALIPER & MICRO METER

Image
INTRODUCTION OF VERNIER CALIPER A calliper is a device used to measure the distance between two opposing sides of an object. It can be as simple as a compass with inward or outward-facing points. First the tips of the calliper are adjusted to fit across the points to be measured and the calliper is then removed and the distance between the tips is measured using a ruler. The modern Vernier calliper was invented by Joseph R. Brown in 1851. It was the first practical tool for exact measurements that could be sold at an affordable price to ordinary machinists.   The Vernier Calliper consists of a main scale fitted with a jaw at one end. Another jaw, containing the vernier scale, moves over the main scale. When the two jaws are in contact, the zero of the main scale and the zero of the Vernier scale should coincide. If both the zeros do not coincide, there will be a positive or negative zero error. Parts of a Vernier Caliper 1.Main Scale The main scale consist...

COORDINATE SYSTEM

Image
CO-ORDINATE SYSTEM A  coordinate system  is a method for identifying the location of a point on the earth. Most  coordinate systems  use two numbers, a  coordinate , to identify the location of a point. Each of these numbers indicates the distance between the point and some fixed reference point, called the origin. QUADRANT FIRST QUADRANT = 0°- 90° ,( X,Y )=( + , + ) SECOND QUADRANT = 90°-180°, ( X,Y )= ( - , + ) THIRD QUADRANT =180°-270°,( X,Y )=( - , - ) FOURTH QUADRANT=270°-360°,( X,Y )=( + ,- ) TYPES OF COORDINATE ABSOLUTE COORDINATE SYSTEM INCREMENTAL COORDINATE SYSTEM POLAR COORDINATE SYSTEM ABSOLUTE COORDINATE SYSTEM Absolute coordinates  refers to a Cartesian System that uses  x-axis ,  y-axis , and sometimes a  z-axis  to establish a point some distance from a common origin. For example, the picture's origin point is '0,0' and the absolute coo...
