Machine Feed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Feed = Uncut Chip Thickness/cos(Side Cutting Edge Angle)
f = t₁/cos(ψ)
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 - (Measured in Meter Per Revolution) - Feed refers to the linear distance the cutting tool travels along the workpiece surface for each revolution of the spindle.
Uncut Chip Thickness - (Measured in Meter) - 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.
Side Cutting Edge Angle - (Measured in Radian) - 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.

STEP 1: Convert Input(s) to Base Unit

Uncut Chip Thickness: 7 Millimeter --> 0.007 Meter (Check conversion here)
Side Cutting Edge Angle: 0.9625508278 Radian --> 0.9625508278 Radian No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f = t₁/cos(ψ) --> 0.007/cos(0.9625508278)

Evaluating ... ...

Side Rake Angle for Orthogonal Cutting

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

Back Rake Angle for Orthogonal Cutting

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

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

Side Cutting Edge Angle for Orthogonal Cutting

Go Side Cutting Edge Angle = acos(Depth of Cut/Cutting Width)

Uncut Chip Thickness

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

Machine Feed

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

Radial Force

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

Feed Force

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

Machine Feed Formula

Feed = Uncut Chip Thickness/cos(Side Cutting Edge Angle)
f = t₁/cos(ψ)

Types of Feed

1)Feed Rate (Turning): In turning, the feed rate is the distance that the cutting tool moves along the axis of the workpiece for each revolution of the spindle.
2)Feed Per Tooth (Milling): In milling, the feed per tooth is the distance that each tooth of the cutter advances into the workpiece for each revolution.
3)Feed Rate (Milling): In milling, the overall feed rate is the distance the workpiece or cutter moves per unit of time.

Factors Affecting Feed Rate

1)Material of Workpiece: Harder materials generally require lower feed rates to avoid excessive tool wear and ensure a good surface finish.
2)Tool Material and Geometry: Different tool materials and geometries can handle different feed rates. Tools with a higher wear resistance can generally handle higher feed rates.
3)Type of Cutting Operation: Different operations such as roughing and finishing require different feed rates. Roughing usually employs higher feed rates for material removal efficiency, while finishing uses lower feed rates for better surface finish and dimensional accuracy.
4)Machine Tool Capabilities: The rigidity and power of the machine tool also limit the feed rate. More robust and powerful machines can handle higher feed rates.
5)Surface Finish Requirements: Higher feed rates typically produce rougher surfaces. For applications requiring a smooth finish, lower feed rates are preferred.
