Title:
METHOD FOR ARTICLE DIMENSIONAL MICRO-POLISHING, DEVICE FOR CARRYING OUT SAID MICRO-POLISHING AND WORKHOLDER FOR A WORKED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2001/066303
Kind Code:
A1
Abstract:
The inventive method is carried out by means of a software-controlled machine tool (1) and a tool whose surface (6) is provided with cutting grains projected from a binding material of the same height. The inventive method makes it possible to polish simultaneously one article and a group of articles. During polishing, multipass reversible displacements are discretely performed with a pitch practically equal to the required micro-roughness heights of the worked surface. An exit time for a system (2) starting operation is defined when a correction of a chip quality parameters is performed in such a way that a resilience dynamic component value does not exceed the required micro-roughness heights at each contact point and a resilience static and dynamic component sum does not exceed an elastic limit value. The inventive device comprises an operation control system (34), a computer and a multi-channel micro-interpolator (41), the outputs thereof being connected to the inputs of drives (12, 13, 14) used for moving a table (9) provided with a workholder (10) for fixing worked articles (11) in accordance with the machine tool's (1) coordinates X, Y and Z. Each drive is provided with a totalizing mechanism which comprises a planetary-pin reducing gear with a cycloid drive.
