Manufacturing Technology

Optical measuring solution for fasteners quality control For operators in the fasteners industry, the quality control of screws is an essential activity. While manufacturing operators generally control screws during work-in-progress execution and at end-of-process, operators in the supply channel need to ensure inbound and outbound compliance to the nominal screw specifications. High-volume production combined with a wide variety of screw models can result in demanding conditions for an operator in this industry, due to the complexity of controls and the time required to carry out the measurements. A wide measurement toolkit library can solve most typical measurement problems, including dimensional, position and form measurements in both static and dynamic modes. Based on 2D optical technology, Optoflash from Marposs has the characteristics to be a reference point in the fasteners industry, for quality controls on small-size products like fasteners. Optoflash is based on area image sensors, and can performmany micrometric precision checks on parts at high speed. Optoflash uses multiple image sensors integrated in fixed positions across the product structure to cover the entire measurement range. This gives the advantage that neither the

image sensors nor the part being measured need to travel along the Z-axis. The operator places a screw in the measuring position and

activates the automatic measuring cycle via the start button. In ten seconds, the Optoflash executes a 360° analysis of the screw and returns a graphical report of the measurements. Through automatic processing and total screw analysis, Optoflash ensures measurement consistency, with high repeatability and reproducibility of the measurements – a performance level that can be difficult to obtain though traditional manual measurement operations. Measurements are displayed as overlays and associated to the real screw image, while colour codes help determine critical conditions on the inspected part. Optoflash features a measurement toolkit dedicated to screws, which integrates the most common controls required. Meas- urement set-up is quick and easy. With a drag-and-drop action, the user can place the measurement directly on the part draw- ing, and input the necessary data, such as the nominal value or the tolerance range. Screws are generally positioned into the Optoflash over a flat faceplate or through a dedicated plug matching the head cavity dimensions and features. They system automatically compensates for variability in the part positioning on the holder and also the possible form errors of the screw. Optoflash analyses screws over 360° degrees and automatically combines several images to determine both part optical axis and the measurements of the features. Marposs Monitoring Solutions offers technologies for in- process monitoring across the whole metal forming industry. Its Brankamp systems are designed to improve productivity and part quality, and reduce production costs. The company Brankamp was founded in 1977 and acquired by Marposs in 2012.
