Turning Surface Roughness Calculator

The irregularities of a surface that results due to the machining process is called as roughness. The irregularities then forms the surface texture. This online turning surface roughness calculator is used to find the roughness of the surface of a tool for a turning operation.

Formula:

Turning Surface Roughness
Ra = ((IPR2 / T * 24) * 1000000) * 1.11 Where, Ra = Turning Surface Roughness IPR = Cutting Feed (IPR) T = Tool Nose Radius

Example

If the cutting feed is 2 and tool nose radius is 3 inch, then roughness is 61666.6667 μin
