G Code is a programming language used to control CNC machines for manufacturing processes.

• G Code consists of commands that tell the machine how to move, cut, or shape the material.

• Each command starts with the letter 'G' followed by a number.

• For example, G00 is a rapid move command, G01 is a linear interpolation command.

• G Code can also include parameters like feed rate, spindle speed, and tool changes.

M codes are machine codes used in CNC programming to control auxiliary functions like coolant or tool changes.

• M codes are used to activate or deactivate specific functions on a CNC machine.

• They are typically followed by a number to specify the exact function to be performed.

• Examples include M06 for tool changes and M08 for coolant activation.

Resistance can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current.

• Use Ohm's Law: R = V / I

• Resistance is measured in ohms (Ω)

• Voltage is measured in volts (V)

• Current is measured in amperes (A)

• Example: If the voltage is 12V and the current is 2A, the resistance would be 6Ω

Colour coding is a system of assigning colours to objects or information to convey meaning or identification.

• Used in various fields such as electronics, wiring, and safety equipment

• Example: Red wire indicates positive polarity in electronics

• Example: Red colour on safety equipment indicates fire hazard

• Helps in quick identification and reduces errors

Color coding is used to identify the resistance value of a resistor.

• The first band represents the first digit of the resistance value.

• The second band represents the second digit of the resistance value.

• The third band represents the multiplier.

• The fourth band represents the tolerance.

• For example, a resistor with brown, black, red, and gold bands has a resistance value of 1.0 ohm with a tolerance of +/- 5%.
