This formula uses 8 Variables

Variables Used

Heat Energy - (Measured in Joule) - Heat Energy is the form of energy that is transferred between systems with different temperatures. It flows from the hotter system to the cooler one until thermal equilibrium is reached.
Metal Density - (Measured in Kilogram per Cubic Meter) - Metal Density is the mass per unit volume of the given metal.
Volume of Metal Melted - (Measured in Cubic Meter) - Volume of Metal Melted is defined as the volume of the material removed during the process of Laser Beam Machining.
Specific Heat Capacity - (Measured in Joule per Kilogram per K) - Specific Heat Capacity is the heat required to raise the temperature of the unit mass of a given substance by a given amount.
Melting Temperature of Base Metal - (Measured in Kelvin) - Melting Temperature of Base Metal is the temperature at which its phase changes from liquid to solid.
Ambient Temperature - (Measured in Kelvin) - Ambient temperature refers to the air temperature of any object or environment where equipment is stored. In a more general sense, it is the temperature of the surrounding environment.
Latent Heat of Fusion - (Measured in Joule per Kilogram) - The Latent Heat of Fusion is the amount of heat required to convert one unit amount of substance from the solid phase to the liquid phase — leaving the temperature of the system unaltered.
Material Reflectivity - Material Reflectivity is the ratio of amount of radiation that is reflected to the total radiation incident.

STEP 1: Convert Input(s) to Base Unit

Metal Density: 10.08 Kilogram per Cubic Meter --> 10.08 Kilogram per Cubic Meter No Conversion Required
Volume of Metal Melted: 0.04 Cubic Meter --> 0.04 Cubic Meter No Conversion Required
Specific Heat Capacity: 0.421 Joule per Kilogram per Celcius --> 0.421 Joule per Kilogram per K (Check conversion here)
Melting Temperature of Base Metal: 1499.999 Celsius --> 1773.149 Kelvin (Check conversion here)
Ambient Temperature: 55.02 Celsius --> 328.17 Kelvin (Check conversion here)
Latent Heat of Fusion: 4599.997 Joule per Kilogram --> 4599.997 Joule per Kilogram No Conversion Required
Material Reflectivity: 0.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = (ρ_m*V*(c*(T_m-θ_ambient)+L_fusion))/(1-R) --> (10.08*0.04*(0.421*(1773.149-328.17)+4599.997))/(1-0.5)

Evaluating ... ...

Q = 4199.9998594176

STEP 3: Convert Result to Output's Unit

4199.9998594176 Joule --> No Conversion Required

FINAL ANSWER

4199.9998594176 ≈ 4200 Joule <-- Heat Energy

How does Laser Beam Machining work ?

Laser (light amplification by stimulated emission of radiation) beam machining (LBM) utilises the energy from the coherent light beams called laser (light amplification by stimulated emission of radiation). The basic principle utilised in LBM is that under proper conditions light energy of a particular frequency is used to stimulate the electrons in an atom to emit additional light with exactly the same characteristics of the original light source.
