    Total Power Consumption in Lathe Machining

    Given Parameters:
    - Outside diameter of the tube: 100 mm
    - Inside diameter of the tube: 96 mm
    - RPM of the workpiece: 120
    - Longitudinal feed: 0.5 mm/rev
    - Cutting ratio: 0.3
    - Tangential force: 800 N
    - Axial force: 600 N

    To calculate the total power consumption in lathe machining, we need to consider the following factors:

    1. Cutting Power:
    The cutting power can be calculated using the formula:
    Cutting Power (Pc) = Tangential Force (Ft) × Cutting Speed (Vc)

    2. Cutting Speed:
    The cutting speed can be calculated using the formula:
    Cutting Speed (Vc) = π × Diameter (D) × RPM / 1000

    3. Feed Power:
    The feed power can be calculated using the formula:
    Feed Power (Pf) = Axial Force (Fa) × Longitudinal Feed (f)

    4. Total Power Consumption:
    The total power consumption can be calculated by adding the cutting power and the feed power:
    Total Power Consumption = Cutting Power + Feed Power

    Now, let's calculate each component step by step:

    1. Cutting Speed:
    Diameter (D) = (Outside Diameter - Inside Diameter) / 2 = (100 mm - 96 mm) / 2 = 2 mm
    Cutting Speed (Vc) = π × 2 mm × 120 RPM / 1000 = 0.7536 m/min

    2. Cutting Power:
    Cutting Power (Pc) = 800 N × 0.7536 m/min = 602.88 W

    3. Feed Power:
    Feed Power (Pf) = 600 N × 0.5 mm/rev = 300 W

    4. Total Power Consumption:
    Total Power Consumption = Cutting Power + Feed Power = 602.88 W + 300 W = 902.88 W

    Therefore, the total power consumption in the lathe machining process is approximately 902.88 W.

    As per the given answer options, the correct answer is between 480 W and 520 W. However, the calculated value is significantly higher than the given range. It is possible that there is an error in the calculations or the answer options provided. Please recheck the calculations or provide additional information if necessary.
