Linear Tool Path-Smoothing Method in High-Speed Machining Based on Error Feasible Area and Curvature Optimization

open access: yesApplied Sciences, 2022
Linear tool path is widely used in high-speed NC machining. However, the geometrical discontinuity of the corner between the linear tool paths will lead to fluctuations in speed, acceleration and jerk, which can excite machinery vibration and reduce the ...

Dual-Bézier path smoothing and interpolation for five-axis linear tool path in workpiece coordinate system

open access: yesAdvances in Mechanical Engineering, 2015
The tool path composed of consecutive short linear segments (G01 blocks) is still the widespread tool path representation form in five-axis machining. The inherent shortcoming of linear tool path is first-order discontinuity at the corner, which is the ...

Artistic Edge and Corner Enhancing Smoothing [PDF]

open access: yesIEEE Transactions on Image Processing, 2007
Two important visual properties of paintings and painting-like images are the absence of texture details and the increased sharpness of edges as compared to photographic images. Painting-like artistic effects can be achieved from photographic images by filters that smooth out texture details, while preserving or enhancing edges and corners.

Spline Trajectory Planning for Road-Like Path with Piecewise Linear Boundaries Allowing Double Corner Points

open access: yesSICE Journal of Control, Measurement, and System Integration, 2018
We consider a problem of trajectory planning for road-like path on the two-dimensional plane. As the basic tool for constructing trajectories, we employ smoothing splines using normalized uniform B-splines as the basis functions.

Corner Smoothing Transition Algorithm for Five-axis Linear Tool Path

open access: yes, 2016
In five-axis machining the trajectory is composed of linear path which has the feature of tangential discontinuity, so that the velocity will be abrupt or be equal to zero at the corner of the adjacent segments. This problem greatly effects the machining

Optimizing the loss function for bounding box regression through scale smoothing

open access: yesAin Shams Engineering Journal
Deep learning technology is widely used in target detection in machine vision. However, existing regression loss functions used for training networks suffer from slow convergence and imprecise localization, hindering the realization of fast and accurate ...
