Feed Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Feed Force = Thrust Force*cos(Side Cutting Edge Angle for Orthogonal Cutting)
F_f = F_t*cos(ψ_s)
This formula uses 1 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Feed Force - (Measured in Newton) - The Feed force acts in the longitudinal direction. It is also called the feed force because it is in the feed direction of the tool. This force tends to push the tool away from the chuck.
Thrust Force - (Measured in Newton) - The Thrust Force is the force applied perpendicular to work-piece in context of Orthogonal Cutting.
Side Cutting Edge Angle for Orthogonal Cutting - (Measured in Radian) - The Side Cutting Edge Angle for Orthogonal Cutting is defined as the angle between the side cutting edge and the side of the shank of the cutting tool. It is often referred to as the lead angle.

STEP 1: Convert Input(s) to Base Unit

Thrust Force: 6.29 Newton --> 6.29 Newton No Conversion Required
Side Cutting Edge Angle for Orthogonal Cutting: 55.1501 Degree --> 0.962550827803944 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_f = F_t*cos(ψ_s) --> 6.29*cos(0.962550827803944)

Evaluating ... ...

F_f = 3.5942853017505

STEP 3: Convert Result to Output's Unit

3.5942853017505 Newton --> No Conversion Required

FINAL ANSWER

3.5942853017505 ≈ 3.594285 Newton <-- Feed Force

Side Rake Angle for Orthogonal Cutting

Go Side Rake Angle = atan((tan(Back Rake Angle)*cos(Side Cutting Edge Angle for Orthogonal Cutting))/(sin(Side Cutting Edge Angle for Orthogonal Cutting)))

Back Rake Angle for Orthogonal Cutting

Go Back Rake Angle = atan(tan(Side Rake Angle)*tan(Side Cutting Edge Angle for Orthogonal Cutting))

Side Cutting Edge Angle for Orthogonal Cutting

Go Side Cutting Edge Angle for Orthogonal Cutting = acos(Depth of Cut/Cutting Width in Machining)

Uncut Chip Thickness

Go Uncut Chip Thickness = Feed*cos(Side Cutting Edge Angle for Orthogonal Cutting)

Machine Feed

Go Feed = Uncut Chip Thickness/cos(Side Cutting Edge Angle for Orthogonal Cutting)

Radial Force

Go Radial Force = Thrust Force*sin(Side Cutting Edge Angle for Orthogonal Cutting)

Feed Force

Go Feed Force = Thrust Force*cos(Side Cutting Edge Angle for Orthogonal Cutting)

Number of Jobs Revolution per Unit Time

Go Number of Revolutions = Cutting Speed/(pi*Initial Diameter of Workpiece)

Initial Diameter of Job in Turning

Go Initial Diameter of Workpiece = Cutting Speed/(pi*Number of Revolutions)

Cutting Speed

Go Cutting Speed = pi*Initial Diameter of Workpiece*Number of Revolutions

Feed Force Formula

Feed Force = Thrust Force*cos(Side Cutting Edge Angle for Orthogonal Cutting)
F_f = F_t*cos(ψ_s)

What is Feed force?

In the metal cutting process, the axial or feed force acts in the longitudinal direction and it is the horizontal component of the cutting force. This force tends to push the tool away from the chuck.

How to Calculate feed force?

The Feed force here is calculated using, feed force = Thrust force * cos ( side cutting edge angle ), The feed force acts in the feed direction of the tool.

How to Calculate Feed Force?

Feed Force calculator uses Feed Force = Thrust Force*cos(Side Cutting Edge Angle for Orthogonal Cutting) to calculate the Feed Force, The feed force, in ORS the cutting is assumed to be uniform and the cutting forces are going to be found in the directions of the velocity and the feed rate (f). These two forces are called Tangential Force (F t) and Feed force (F f). Feed Force is denoted by F_f symbol.

How to calculate Feed Force using this online calculator? To use this online calculator for Feed Force, enter Thrust Force (F_t) & Side Cutting Edge Angle for Orthogonal Cutting (ψ_s) and hit the calculate button. Here is how the Feed Force calculation can be explained with given input values -> 3.594285 = 6.29*cos(0.962550827803944).

FAQ

What is Feed Force?

The feed force, in ORS the cutting is assumed to be uniform and the cutting forces are going to be found in the directions of the velocity and the feed rate (f). These two forces are called Tangential Force (F t) and Feed force (F f) and is represented as F_f = F_t*cos(ψ_s) or Feed Force = Thrust Force*cos(Side Cutting Edge Angle for Orthogonal Cutting). The Thrust Force is the force applied perpendicular to work-piece in context of Orthogonal Cutting & The Side Cutting Edge Angle for Orthogonal Cutting is defined as the angle between the side cutting edge and the side of the shank of the cutting tool. It is often referred to as the lead angle.

How to calculate Feed Force?

The feed force, in ORS the cutting is assumed to be uniform and the cutting forces are going to be found in the directions of the velocity and the feed rate (f). These two forces are called Tangential Force (F t) and Feed force (F f) is calculated using Feed Force = Thrust Force*cos(Side Cutting Edge Angle for Orthogonal Cutting).
