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 precision of measurements taken using the micrometer.

G & M code is a language used in CNC programming to control the movements and functions of a machine tool.

• G code specifies the movements and positions of the tool, such as cutting speed and tool path.

• M code controls auxiliary functions like coolant flow or spindle speed.

• Examples: G01 is a linear interpolation command, M03 is spindle on clockwise command.
