Least count of a micrometer is the smallest measurement that can be read on the scale of the micrometer.
Least count is calculated by dividing the smallest division on the main scale by the total number of divisions on the circular scale.
For example, if the smallest division on the main scale is 0.5 mm and there are 50 divisions on the circular scale, the least count would be 0.5 mm / 50 = 0.01 mm.
It determines the...
G & M code is a language used in CNC programming to control the movements and functions of a machine tool.

Example: TRUNCATE TABLE table_name;
Example: DELETE FROM table_name WHERE condition;
Example: DROP TABLE table_...
