Turbo-Abrasive Machining [TAM] is a mechanical deburring and finishing method originally developed primarily to automate edge finishing procedures on complex rotationally oriented and symmetrical aerospace engine components. Since its inception this method of utilizing fluidized free abrasive materials has facilitated significant reductions in the amount of manual intervention required to deburr large components by these manufacturers. Additionally, the process has also proved to be useful in edge and surface finishing a wide variety of other non-rotational components by incorporating these components into fixturing systems. The advantages of this method go beyond the simple removal or attenuation of burrs. The method is also capable of producing surface conditions on these critical edge and surface areas that contribute to increased service life and functionality of parts that are severely stressed in service. Among these are: (1) the creation of isotropic surface conditions. (2) the replacement of positively skewed surface profiles with negative or neutral skews and (3) the development of beneficial compressive stress and development of a stress equilibrium among part features
