    Study Notes

    Numerical Control (NC)

    • Numerical Control (NC) refers to the automation of machine tools through the use of numerical data.

    CNC Machines

    • In CNC, instructions are stored in the computer's memory.
    • CNC machines operate based on coded instructions that control their movements.

    Types of Codes

    • CNC machines operate using G-codes and M-codes, which control their movements and actions.

    Direct Numerical Control (DNC)

    • Direct Numerical Control (DNC) involves direct connection of multiple CNC machines to a central computer, allowing for simultaneous control.

    Advantages of CNC

    • One of the advantages of CNC is increased productivity due to the ability to automate repetitive tasks.

    Basic Components of NC System

    • The three basic components of an operational NC system are a machine tool, a control system, and a data input device.

    NC vs CNC

    • The key difference between NC and CNC is that NC systems use a fixed, punched tape to store instructions, while CNC systems use a computer to store and execute instructions.

    Direct Numerical Control (DNC)

    • Direct Numerical Control (DNC) involves direct connection of CNC machines to a central computer, allowing for simultaneous control and monitoring.

    Control of CNC Machines

    • CNC machines operate based on coded instructions that control their movements and actions.

    Contribution to Productivity

    • CNC contributes to increased productivity by automating repetitive tasks, reducing human error, and improving accuracy.
