Proportion of Cutting Edge Engagement for Face Milling Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time Proportion of Cutting Edge Engagement = asin(Work Engagement/Diameter of A Cutting Tool)/pi
Q = asin(a_e/D_t)/pi
This formula uses 1 Constants, 2 Functions, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
asin - The inverse sine function, is a trigonometric function that takes a ratio of two sides of a right triangle and outputs the angle opposite the side with the given ratio., asin(Number)

Variables Used

Time Proportion of Cutting Edge Engagement - Time Proportion of Cutting Edge Engagement is the fractional portion of machining time during which the Cutting Edge of the tool is engaged with the workpiece.
Work Engagement - (Measured in Meter) - Work Engagement is the instantaneous contact geometry between the cutter and the in-process workpiece during machining.
Diameter of A Cutting Tool - (Measured in Meter) - The Diameter of a Cutting Tool is the outer diameter of the cutting part of the tool.

STEP 1: Convert Input(s) to Base Unit

Work Engagement: 52 Millimeter --> 0.052 Meter (Check conversion here)
Diameter of A Cutting Tool: 54.67604 Millimeter --> 0.05467604 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = asin(a_e/D_t)/pi --> asin(0.052/0.05467604)/pi

Evaluating ... ...

Q = 0.399999922245133

STEP 3: Convert Result to Output's Unit

0.399999922245133 --> No Conversion Required

Proportion of Cutting Edge Engagement for Face Milling

Go Time Proportion of Cutting Edge Engagement = asin(Work Engagement/Diameter of A Cutting Tool)/pi

Diameter of Tool given Proportion of Edge Engagement for Face Milling

Go Diameter of A Cutting Tool = Work Engagement/sin(Time Proportion of Cutting Edge Engagement*pi)

Work Engagement given Proportion of Edge Engagement for Face Milling

Go Work Engagement = sin(Time Proportion of Cutting Edge Engagement*pi)*Diameter of A Cutting Tool

Maximum Chip Thickness in Vertical Milling

Go Maximum Chip Thickness = Feed Speed/(Number of Teeth on Cutting Tool*Rotational Frequency)

Feed Speed in Vertical Milling given Maximum Chip Thickness

Go Feed Speed = Maximum Chip Thickness*Number of Teeth on Cutting Tool*Rotational Frequency

Machining Time for Shaping Operation

Go Machining Time = Width of Workpiece/(Feed Rate*Frequency of Reciprocating Strokes)

Machining Time for Milling Operation

Go Machining Time = (Length of Workpiece+Length of Approach)/Feed Speed

Minimum Length of Approach required in Face Milling

Go Length of Approach = Diameter of Cutting Tool/2

Proportion of Cutting Edge Engagement for Face Milling Formula

Time Proportion of Cutting Edge Engagement = asin(Work Engagement/Diameter of A Cutting Tool)/pi
Q = asin(a_e/D_t)/pi

What causes flank wear?

Flank Wear is most commonly caused due to abrasive wear of the cutting edge against the machined surface. Flank Wear generally occurs when the speed of cutting is very high. It causes many losses but one of the most concerning is the increased roughness of the surface of the final product.
