Space corner smoothing of CNC machine tools through developing 3D general clothoid
Robotics and Computer-Integrated Manufacturing, 2020Tool paths defined by G01/G02/G03 commands need to be smoothed to eliminate the discontinuities of velocity, acceleration and jerk at the junction points.

The linear motion command (G01) is a widely used command format in CNC machining. However, the tangential direction discontinuity at the corner junction will cause velocity fluctuations and excite the structural vibration of machine tools.

Partial smoothing splines for noisy +boundaries with corners
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1993 Investigates the estimation of 2-D boundary functions from sampled data sets where both noise and corners are present. The approach is based on the partial smoothing spline in which the estimated boundary function consists of an ordinary smoothing spline and a parametric function that describes the discontinuities (i.e., corners of the boundary). Prior

(B.6)Corner trajectory smoothing with asymmetrical transition profile for CNC machine tools
International Journal of Machine Tools and Manufacture, 2019The linear toolpaths, so-called G01 blocks, are widely used in CNC machining. Since this non-smooth path only achieves position continuity at the corner junction, it is prone to cause speed fluctuations and excite structural vibrations, which is not ...

Corner smoothing interpolation algorithm based on PH curve
2019 3rd International Conference on Electronic Information Technology and Computer Engineering (EITCE), 2019In the process of machining, sharp corners will exist at the joints of continuous short line segments, and most spline curves cannot establish the accurate relationship between arc length and parameters.

On robust corner preserving smoothing in image processing. [PDF]
, 2003 This Ph.D. thesis treats consistency, robustness and dicontinuity-preserving issues of M-kernel estimators in one- and two-dimensional regression. The M-kernel smoother was first introduced by Härdle and Gasser (1984) who provide a restricted valid proof of consistency for a monotone score function and show the minimax property. Chu et al.

Corner detection using iterative Gaussian smoothing with constant window size
Pattern Recognition, 1995Abstract In contrast to the existing Gaussian smoothing process with varying window size, an iterative Gaussian convolution with constant window size is proposed. The iterative process is shown to converge as the norm of the convolution matrix is less than unity. For a closed digital curve the number of iterations is shown to be related to the number
