Abstract
Methods suitable for producing textured surfaces in surfaces of objects, by which the methods are able to achieve a desired three-dimensional surface topography and optionally a desired subsurface microstructure through the use of a controlled modulation machining technique. The methods include selecting a predetermined surface texture for a surface of a body, and then imposing a superimposed sinusoidal feed-modulation on a cutting tool so as to move the cutting tool in a feed direction relative to the body while machining the body with the cutting tool and generating a machined surface of the body. The surface texture of the machined surface is intentionally controlled by at least the modulation amplitude and the modulation frequency of the superimposed sinusoidal feed-modulation.
