Corner cutting with trapezoidal augmentation for area-preserving smoothing of polygons and polylines

CAD Computer Aided Design, 2011
Abstract Recently, a new subdivision method was introduced by the author for smoothing polygons and polylines while preserving the enclosed area [Gordon D. Corner cutting and augmentation: an area-preserving method for smoothing polygons and polylines. Computer Aided Geometric Design 2010; 27(7):551–62].

Curvature-continuous sharp corner smoothing scheme for Cartesian motion systems

2014 IEEE 13th International Workshop on Advanced Motion Control (AMC), 2014
In general practice, a geometric tool-path for CNC (computer numerical controlled) machine tools or NC positioning systems is mainly composed of linear motion segments, or so called the G1 commands. This approach exhibits serious limitations in terms of achieving the desired part geometry and productivity in high-speed machining.

An Analytical C3 Continuous Local Corner Smoothing Algorithm for Four-Axis Computer Numerical Control Machine Tools

, 2018
Linear motion commands of multi-axis computer numerical control (CNC) machine tools need to be smoothed at the transition corners, because the velocity discontinuities at corners can result in fluctuations on machine tool motions and lead to poor surface

A newly developed corner smoothing methodology based on clothoid splines for high speed machine tools

Robotics Comput. Integr. Manuf., 2021
Continuous linear commands are widely executed in computer numerical control (CNC) machining. The tangential discontinuity at the junction of consecutive segments restricts the machining efficiency and deteriorates the surface quality.

B-spline based corner smoothing method to decrease the maximum curvature of the transition curve

Journal of manufacturing science and engineering, 2021
Toolpath represented by linear segments leads to tangency discontinuity between blocks, which results in fluctuation of feedrate and reduction of machining efficiency and quality.
