PRODUCTIVITY OF EDGE ROUNDING BY FACE POLYMERIC ABRASIVE BRUSHES
The PURPOSE of the paper is to determine the consistent influence patterns of machining parameters of face polymeric abrasive brushes on the productivity of rounded edge formation. METHODS. Researches were conducted by an experimental method on 3M Сompany (Minnesota Mining and Manufacturing Company) face brushes of Scotch-Brite™ BD-ZB brands of different coarseness. RESULTS AND THEIR DISCUSSION. The article considers the process of edge formation. Consistent patterns of the influence of rotating speed, deformation and feed on the size of the machined edge have been determined for the case when the machined edge is located along the brush axis and when it is axis-bias on different distances. The productivity of the edge formation process depends on brush location relative to the machined edge, quantity of bristles participating in the interaction with the machined surface and from the direction of bristle impact on the processed edge. The received results are presented in the form of mathematical dependences. CONCLUSION. Application of face polymeric abrasive brushes for rounding edges allows to meet all the requirements for the size and roughness of the machined edges. The obtained equations allow to determine the processing modes providing the required productivity of the process.
