Filament winding is a process of placement of reinforcement fibers on to a rotating surface in a specified geometric patern. A conventional straight line interpolation controller is not very appropriate for filament winding because the fiber pay-out-eye is at some distance away from the mandrel surface and its movement from one point to another disturbs the previous fiber positions on the mandrel. Also, the speed of carriage movement is much higher in filament winding and path accuracy requirements are not as high as in conventional cutting machines. Filament winding demands a controller which can produce fast and smooth carnage movements, and have a look-ahead capability so that while moving around curvatures the effect of pay-out-eye movement on previous fiber positions is minimal. This problem can be overcome by using an interpolation technique which determines the profile by considering more than two data points, and whose derivative is continuous in nature. In this project an IBM PC based filament winding controller, using B spline interpolation technique, is developed. Its performance is tested and compared with straight line interpolation controller on a three axis filament winding machine which is also developed at Nottingham University. The results show a considerable improvement in the winding speed and the accuracy of fiber placement. |
