TECHNOLOGY EXECUTIVE SUMMARY.  The technology is currently used in the United States to deburr and contour the edges of complex parts and to create isotropic surface finishes essential in finishing many complex parts.  Unlike single-point-of-contact machining technologies the technology is relatively simple to control once process parameters for a given part have been developed, and thus enjoys the attributes of reliability and repeatability of simpler mechanical (vs. digital feedback) technologies. However, It accomplishes uniform results on very complex parts that often cannot be achieved reliably by other much more complex processes.   The technology involves developing a fluidized bed of media in which the part to be processed is partially immersed while being rotated.  A wide variety of differing results may be achieved by varying the process parameters (media, process time, rotational speed etc.).  Process results can be closely controlled and are programmable, and are totally repeatable, providing unequaled process quality control.  The process is dry, and involves no chemicals or environmentally unfriendly materials. There are a number of other applications for this technology, which are not yet introduced into the United States.  The process has been shown to minimize hand-deburring operations, parts are deburred and finished rapidly, typically in time cycles of only a few minutes.  Contact Dr. Massarsky for additional information.

DRY MECHANICAL EDGE AND SURFACE FINISHING FOR ROTATING AEROSPACE COMPONENTS (New York, NY — July 24, 2018) Turbo-Abrasive Machining (TAM) is a new process for deburring and surface conditioning sophisticated multi-axis machined parts. Many parts, because of size and shape factors, cannot be finished by a mass media technique but need manual intervention for final abrasive finishing. Apart from safety and production line/time considerations, a significant disadvantage of manual deburring is its impact on quality control and assurance procedures, which have often been computerized at great cost. The TAM process addresses these problems by automating the final machining and finishing production steps. In TAM, fluidized bed technology is utilized to suspend abrasive or even peening materials in a specially designed chamber: Part surfaces are exposed to and interact with the fluidized bed materials on a continuous basis by high speed rotational or oscillational motion in an entirely dry environment.
The combination of abrasive envelopment and high speed rotating contact can produce important functional metal surface conditioning effects and deburring and radius formation very rapidly. Because abrasive operations are performed on all parts of rotating components simultaneously, the part and feature uniformities achieved are very hard to duplicate by other methods. In addition, sophisticated computer control technologies can be applied to create processes tailored for particular parts. Although the abrasive materials used for TAM processing are in some ways similar to grinding and blasting materials, the surface condition produced is unique. One reason for this is the multi-directional and rolling nature of abrasive particle or peening particle contact with part surfaces. Surfaces are characterized by a homogenous, finely blended abrasive pattern developed by the non-perpendicular nature of abrasive attack. There is no perceptible temperature shift in the contact area and the micrto-textured random abrasive pattern is a highly attractive substrate for subsequent coating operations. In addition to the foregoing, the process has an additional advantage, in that it develops significant beneficial compressive stress and stress equilibrium in parts as well as edge and surface finish conditions that are isotropic, plateaued or planarized surface characteristics and have negatively or neutrally skewed low micro-inch surface profiles.
