Specific Power Consumption Solution

Follow our step by step solution on how to calculate Specific Power Consumption?

FIRST Step Consider the formula

SPC = \frac{F metal cutting}{w \cdot F cutter}

Next Step Substitute values of Variables

∴

SPC = \frac{2.5N}{255mm \cdot 12mm}

Next Step Convert Units

∴

SPC = \frac{2.5N}{0.255m \cdot 0.012m}

Next Step Prepare to Evaluate

∴

SPC = \frac{2.5}{0.255 \cdot 0.012}

Next Step Evaluate

∴

SPC = 816.993464052288W

LAST Step Rounding Answer

∴

SPC = 816.9935W

Specific Power Consumption Formula Elements

Variables

Specific Power Consumption

Specific Power Consumption is the power consumed per unit mass.

Symbol: SPC

Measurement: PowerUnit: W

Note: Value should be greater than 0.

Formulas to find Specific Power Consumption

Force

Force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity.

Symbol: F_{metal cutting}

Measurement: ForceUnit: N

Note: Value should be greater than 0.

Formulas to find Force

Width

Width is the measurement or extent of something from side to side.

Symbol: w

Measurement: LengthUnit: mm

Note: Value can be positive or negative.

Formulas to find Width

Feed

Feed is the rate at which a cutter moves through material.

Symbol: F_cutter

Measurement: LengthUnit: mm

Note: Value can be positive or negative.

Formulas to find Feed

Go Shear Angle

ϕ = a \tan (w \cdot \frac{\cos (θ)}{1 - w \cdot \sin (θ)})

Go Shear Force

F s = Fc \cdot \cos (θ) - P t \cdot \sin (θ)

Go Shear Plane Angle

ϕ = \arctan (\frac{r \cdot \cos (α)}{1 - r \cdot \sin (α)})

Go Shear Strain

𝜂 = \tan (ϕ) + \cot (ϕ - α)
