CNC centralized control for digitizing freeform surfaces by means of a conoscopic holography sensor integrated in a machining centre

Abstract: This paper presents the integration of a conoscopic holography sensor (CH) in a machining centre (MC) by means of a centralized control on the machine's CNC (CNC centralized control). Besides the installation and extrinsic calibration of the sensor, the primary focus is the automation of the freeform digitizing [...]

A Gaussian filtering method to reduce directionality on high-density point clouds digitized by a conoscopic holography sensor

Abstract: This work analyses the directional effect shown by the high-density point clouds digitized with a conoscopic holography (CH) sensor. The asymmetric shape of the laser spot for this sensor yields directionality to appear along the largest spot dimension and to occur repeatedly under different working conditions. To study [...]

Conoscopic holography systematic error processing by means of Gaussian filters

Abstract: This work analyses the directional effect shown by the point clouds when digitizing with a conoscopic holography (CH) sensor. The asymmetric shape of the laser spot for this sensor yields that directionality appears along the greatest spot length and it occurs repeatedly under different [...]

On-machine geometric inspection by means of Conoscopic Holography applied to freeform surfaces generated by milling

Abstract: The current requirement of precision on freeform surface machining, as well as productivity necessities which facilitate the supply of high-quality products to the market, have promoted an important progress on integration of machining and inspection stages on machining centres. On Machine Measuring techniques (OMM) [...]
