Here is how the Machine Feed equation looks like.

0.0123 = \frac{7}{\cos (0.9626)}

0.0123m/rev = \frac{7mm}{\cos (0.9626rad)}

0.0123 = \frac{7}{\cos (0.9626)}

Machine Feed Solution

Follow our step by step solution on how to calculate Machine Feed?

FIRST Step Consider the formula

f = \frac{t 1}{\cos (ψ)}

Next Step Substitute values of Variables

∴

f = \frac{7mm}{\cos (0.9626rad)}

Next Step Convert Units

∴

f = \frac{0.007m}{\cos (0.9626rad)}

Next Step Prepare to Evaluate

∴

f = \frac{0.007}{\cos (0.9626)}

Next Step Evaluate

∴

f = 0.0122500014059282m/rev

LAST Step Rounding Answer

∴

f = 0.0123m/rev

Functions

Feed

Feed refers to the linear distance the cutting tool travels along the workpiece surface for each revolution of the spindle.

Symbol: f

Measurement: FeedUnit: m/rev

Note: Value should be greater than 0.

Formulas to find Feed

Uncut Chip Thickness

Uncut chip thickness refers to the thickness of the material layer being removed by each cutting edge during a single tooth engagement in metal cutting operations.

Symbol: t₁

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Uncut Chip Thickness

Side Cutting Edge Angle

Side cutting edge angle refers to the angle formed between the side cutting edge of the tool and a line perpendicular to the workpiece surface.

Symbol: ψ

Measurement: AngleUnit: rad

Note: Value should be greater than 0.

Formulas to find Side Cutting Edge Angle

cos

Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle.

Syntax: cos(Angle)

How to Evaluate Machine Feed?

Machine Feed evaluator uses Feed = Uncut Chip Thickness/cos(Side Cutting Edge Angle) to evaluate the Feed, Machine feed, often simply referred to as "feed," is a crucial parameter in metal cutting operations. It represents the distance that the cutting tool advances into the workpiece for each revolution of the spindle or each cutting stroke. Feed is denoted by f symbol.

How to evaluate Machine Feed using this online evaluator? To use this online evaluator for Machine Feed, enter Uncut Chip Thickness (t₁) & Side Cutting Edge Angle (ψ) and hit the calculate button.

FAQs on Machine Feed

What is the formula to find Machine Feed?

The formula of Machine Feed is expressed as Feed = Uncut Chip Thickness/cos(Side Cutting Edge Angle). Here is an example- 0.01225 = 0.007/cos(0.9625508278).

How to calculate Machine Feed?

With Uncut Chip Thickness (t₁) & Side Cutting Edge Angle (ψ) we can find Machine Feed using the formula - Feed = Uncut Chip Thickness/cos(Side Cutting Edge Angle). This formula also uses Cosine (cos) function(s).

Can the Machine Feed be negative?

No, the Machine Feed, measured in Feed cannot be negative.

Which unit is used to measure Machine Feed?

Machine Feed is usually measured using the Meter Per Revolution[m/rev] for Feed. Millimeter Per Revolution[m/rev] are the few other units in which Machine Feed can be measured.
