Surface Finish Constraint Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Constraint on Feed - (Measured in 1 per Meter) - Constraint on Feed is the maximum feed that can be used while machining.
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_s = 0.0321/r_nose --> 0.0321/0.107

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 Constraint on Feed = 0.0321/Nose Radius to calculate the Constraint on Feed, Surface finish constraint limits the maximum feed that can be used to attain the required surface finish on the machined feature. Constraint on Feed is denoted by C_s 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 -> 0.061731 = 0.0321/0.107.
