A method of abrading a surface of a workpiece comprises agitating a vessel containing loose abrasive bodies and the workpiece. At least most of the loose abrasive bodies have a maximum dimension of 0.25 to 3 centimeters. On a respective basis, each loose abrasive body comprises abrasive particles secured to an organic substrate by a binder material. The vessel is agitated with sufficient energy such that at least some of the loose abrasive bodies contact and abrade at least a portion of the surface of the workpiece. A plurality of chopped loose abrasive bodies, wherein, on a respective basis, the chopped loose abrasive bodies each comprise abrasive particles secured to a substrate and have a maximum dimension of 0.25 to 1.5 centimeters is also disclosed.

A method of modifying a surface of a workpiece comprises providing a system comprising a sealed mixing vessel having an interior chamber wherein the workpiece and working bodies are contained. The sealed mixing vessel is then uniaxially vibrated at a frequency between 15 hertz and 1 kilohertz, and at a vibrational amplitude between about 0.2 cm and 3 cm such that the working bodies impact the surface of the workpiece. The method is useful for shot peening and abrasive finishing the workpiece.
