Information on roughness The surface finish is highly depended on the the cutting tool’s action and instability, errors in tool guide ways and deformations caused by stress patterns In manufacturing, roughness is caused by a material’s microstructure and the cutting tool’s action on the material. This is where variables like tool shape, speed, feed and cutting fluid come into play. roughness- includes the finest (shortest wavelength) irregularities of a surface. Roughness generally results from a particular production process or material condition There is an inverse relation between the cutting speed and the arithmetic mean value (Ra/ Surface roughness of a machined surface depends on: (a) geometrical factors (b) work material factors, (c) vibrations and machine tool factors 590 Chapter 24/Economic and Product Design Considerations in Machining The effect of nose radius and feed can be combined in an equation to predict the ideal average roughness for a surface produced by a single-point tool. The equation applies to operations like
