Surface Finish Constraint Solution

STEP 0: Pre-Calculation Summary

Formula Used

Feed Constraint = 0.0321/Nose Radius
C = 0.0321/r_nose
This formula uses 2 Variables

Variables Used

Feed Constraint - (Measured in 1 per Meter) - feed constraint rate refers to the distance that the cutting tool advances along the workpiece per revolution of the workpiece or per tooth of the tool in milling.
Nose Radius - (Measured in Meter) - Nose Radius is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length.

STEP 1: Convert Input(s) to Base Unit

Nose Radius: 0.107 Meter --> 0.107 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C = 0.0321/r_nose --> 0.0321/0.107

Evaluating ... ...

C = 0.3

STEP 3: Convert Result to Output's Unit

0.3 1 per Meter --> No Conversion Required

FINAL ANSWER

0.3 1 per Meter <-- Feed Constraint

What is Surface finish constraint?

Surface finish constraint limits the maximum feed that can be used to attain the required surface finish on the machined feature. This constraint becomes active during finish turning. The expression or CLA value of the geometric surface finish obtained during turning operation with a tool of nose radius ‘r’ is taken into account to obtain this constraint.

How to Calculate Surface Finish Constraint?

Surface Finish Constraint calculator uses Feed Constraint = 0.0321/Nose Radius to calculate the Feed Constraint, Surface finish constraint limits the maximum feed that can be used to attain the required surface finish on the machined feature. Feed Constraint is denoted by C symbol.

How to calculate Surface Finish Constraint using this online calculator? To use this online calculator for Surface Finish Constraint, enter Nose Radius (r_nose) and hit the calculate button. Here is how the Surface Finish Constraint calculation can be explained with given input values -> 0.3 = 0.0321/0.107.

FAQ

What is Surface Finish Constraint?

Surface finish constraint limits the maximum feed that can be used to attain the required surface finish on the machined feature and is represented as C = 0.0321/r_nose or Feed Constraint = 0.0321/Nose Radius. Nose Radius is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length.

How to calculate Surface Finish Constraint?
