Abstract

This paper presents a compensation system based on wheel online dressing and online measuring. Because of its excellent dressing performance, the Green-Carbon wheel Dresser was chosen to dress the diamond wheel. And a measurement system was put forward, which included the method of diamond wheel arc detecting with displacement sensor, radius filtering, and the least-squares curve fitting. Considering the radius calculated, the compensation controlling points can be obtained. Compared with the traditional error compensation technology, advantages of this system include four aspects: no new error is brought due to the complete online operation; introducing a GC wheel dresser with tilting structure and lagging-dress method can enhance the dressing accuracy; the operation is convenient, because there is no need to make strict equal-angle measurement and to confirm zero setting; processing data through radius constraining and filtering can reach a high fitting precision, which is useful to the compensation machining later. Keywords: online dressing, online measuring, filtering, least squares method
