PROCESSO E APARELHO PARA USINAR ABRASIVAMENTE E ESMERILAR UMA PECA DE TRABALHO |
摘要 |
<p>A method and apparatus for abrasively machining a workpiece (12) includes the establishment of an eddy-current in the workpiece (12) at an area (33) where an abrasive tool (14) contacts the workpiece (12). …<??>Heretofore it has not been possible to adaptively control an abrasive machining operation as a function of changes occurring in the microstructure of the workpiece (12) during the machining operation. In particular, it has not been possible to detect non-visible grinder burn on the surface of a workpiece during a grinding operation. …<??>The present invention solves the above problem by providing an abrasive machining apparatus (10) having a means (32) for establishing an eddy-current in a workpiece (12) at an area (33) where a tool (14) contacts the workpiece (12) and sensing any change in the eddy-current in response to change in the microstructure of the workpiece (12) resulting from the abrasive machining operation. …<??>The method and apparatus of the present invention is particularly useful for grinding hardened ferrous metal workpieces without incurring grinder burn defects.</p> |
