Abstract
The common quality assurance in the manufacturing process of gears is based on production-related tactile measurements using coordinate measurement machines (CMM). Due to this, the quality assurance is limited to random testing during the manufacturing process and usually a complete final inspection of the manufactured gears. Common data processing algorithms for gear metrology are the L2-norm (Gaussian-norm) or L1-norm combined with a minimization algorithm like the downhill simplex method. This paper shows new methods in gear measurement and data processing, which allows a fast in-line (lathe integrated) inspection of gears. The measurement system consists of an optical distance sensor, the synchronization electronics and the digital data processing. The developed angle-equidistant measurement enables the use of spectral analytic methods to characterize gears for the first time. By using different digital methods like Goertzel's algorithm, discrete Fourier transform (DFT) or fast Fourier transform (FFT) in data processing, clamping errors, eccentricity, distortion, geometry variations (deformation or material allowance variations) and other possible errors can be detected. By integration of the measurement system into a lathe, the errors can be detected even before the cutting process starts in order to avoid low quality or scrap. For different types of gears, the results are shown with a focus on accuracy, standard deviations, computational effort and performance.
