The surface texture of a mechanical part can have a large impact on performance and durability. Certain patterns can be generated by the milling process, which is better at retaining fluids, such as oil, and reduces the wear on parts. Any part, from hydraulics to bearings, could benefit from surface texturing. Currently texturing requires etching or lithography techniques, which are difficult to scale up to production quantities.

Purdue University researchers have developed Modulation-Assisted Machining (MAM), a technology that implements surface texturing during the normal course of production. By incorporating modulation to the milling, repeated textures are worked into the piece without any changes to the fabrication process. Since the new pattern is added while the part is being milled, no additional processing time or cost is incurred.

Advantages:
-Achieves better performance and durability for mechanical parts
-No significant impact on production time or cost
-Texturing is added during fabrication

Potential Applications:
-Manufacturing
-Parts manufacturers
