Real-time graphic visualization of filament band winding for fiber-reinforced cylindrical vessels

Abstract

The filament winding method is widely used to manufacture lightweight, strong, composite products. To reduce winding time, the method of winding by filament band, which consists of several roving tows, is used. A computer numerical control winding machine is used with input path commands for precise winding operation. Before filament winding, users should verify by simulation that the input path is appropriate for the winding without any erroneous operation. Furthermore, prior to starting the winding operation, the usage length of each tow must to be checked because the manufacturing process stops unexpectedly if the tow on the creel runs out. In this work, we used the geodesic equation to generate a filament band surface and calculate the usage length of each tow. We also proposed a graphic display method to make the visual effect in accord with the real winding process. To verify the presented algorithm, a program for three-dimensional real-time graphic visualization of filament band winding process was developed.

Construction of algorithms to automatically determine individual indicators when assessing the shape quality of cross-wound packages

“…The unwound thread does not return to the production process. Study [12] describes a real-time system that controls stacking of a fiber thread in winding when forming cylindrical parts made of composite materials. The system makes it possible to control deviations in the shape of winding due to cylindricity.…”

“…As a rule, the yarns are laid on the same place with a periodicity equal to the denominator n in the ratio between the bobbin and the yarn feeder. It is shown in [14][15][16] that the larger n, the fewer threads in the bundle and the lesser danger it presents for the appearance of breaks when the bobbin is unwound. Externally, the bundle winding is manifested in the form of protrusions on the side surface of the pack age, located at an elevation angle -a turn to the axis of the package.…”

Determining the dependences for calculating a conversion scale of profile height of the controlled packing surface

“…The device described in [6] is the development of systems based on scanning the image of a bobbin by the laser beam, such as Beltro-Lis [7], manufactured by Barmag AG (Germany). The system records the presence of torn elementary threads, stains and dirt, as well as controls the contours of packings.…”
