Optical comparator (original) (raw)
Il proiettore di profili (in inglese optical profile projector o optical comparator) è un apparecchio industriale ad amplificazione ottica usato per eseguire misure bidimensionali di precisione al centesimo di millimetro. Esso funziona in sinergia con un software, per esempio il , che elabora le misurazioni. Questo macchinario serve per misurare la precisione di ruote dentate, filettature e . Usato nell'industria metalmeccanica, può essere azionato in modo manuale o meccanico.

| dbo:abstract | Un comparador óptico (a menudo llamado simplemente comparador en el contexto) o proyector de perfiles es un dispositivo que aplica los principios de la óptica a la inspección de piezas fabricadas. En un comparador, la silueta ampliada de una pieza se proyecta sobre la pantalla, y las dimensiones y la geometría de la pieza se miden con respecto a los límites prescritos. Es un elemento útil en un taller mecanizado de piezas pequeñas o en una línea de producción para el equipo de inspección de control de calidad. La medición se realiza de varias maneras. La más sencilla es que las graduaciones de la pantalla, superpuestas sobre la silueta, permiten al observador medir, como si se colocara una regla clara sobre la imagen. Otra forma es que varios puntos de la silueta se alineen con el retículo en el punto central de la pantalla, uno tras otro, moviendo la platina sobre la que se asienta la pieza, y una lectura digital informa de cuánto se ha movido la platina para alcanzar esos puntos. Por último, los métodos más avanzados tecnológicamente implican un software que analiza la imagen e informa de las mediciones. Los dos primeros métodos son los más comunes; el tercero es más reciente y no está tan extendido, pero su adopción es continua en la era digital. (es) An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are measured against prescribed limits. It is a useful item in a small parts machine shop or production line for the quality control inspection team. The measuring happens in any of several ways. The simplest way is that graduations on the screen, being superimposed over the silhouette, allow the viewer to measure, as if a clear ruler were laid over the image. Another way is that various points on the silhouette are lined up with the reticle at the centerpoint of the screen, one after another, by moving the stage on which the part sits, and a digital read out reports how far the stage moved to reach those points. Finally, the most technologically advanced methods involve software that analyzes the image and reports measurements. The first two methods are the most common; the third is newer and not as widespread, but its adoption is ongoing in the digital era.
