Global toolpath smoothing for CNC machining based on B-spline approximation with tool tip position adjustment

open access: yesThe International Journal of Advanced Manufacturing Technology, 2023
B-spline curve approximation is widely used for fitting linear toolpaths to improve machining quality and efficiency in CNC machining. For a high-quality smoothing method, the control of both approximation error and curve curvature needs to be taken into

Approximation by Conic Splines [PDF]

open access: yesMathematics in Computer Science, 2007
We show that the complexity of a parabolic or conic spline approximating a sufficiently smooth curve with non-vanishing curvature to within Hausdorff distance $\varepsilon$ is $c_1\varepsilon^{-\frac{1}{4}} + O(1)$, if the spline consists of parabolic arcs, and $c_2\varepsilon^{-\frac{1}{5}} + O(1)$, if it is composed of general conic arcs of varying ...

Optimization of spline parameters in approximation of multivalued functions

open access: yesРоссийский технологический журнал, 2023
Objectives. Methods for spline approximation of a sequence of points in a plane are increasingly used in various disciplines. A spline is defined as a single-valued function consisting of a known number of repeating elements, of which the most widely ...

Cubic B-spline approximation for linear stochastic integro-differential equation of fractional order

open access: yesJournal of Computational and Applied Mathematics, 2020
In this paper, the cubic B-spline collocation method is used for solving the stochastic integro-differential equation of fractional order. we show that stochastic integro-differential equation of fractional order is equivalent to a modified stochastic ...

A numerical study on time fractional Fisher equation using an extended cubic B-spline approximation

open access: yesJournal of Mathematics and Computer Science, 2020
A new extended cubic B-spline approximation for the numerical solution of the time-fractional fisher equation is formed and examined. The given non-linear partial differential equation through substitution is converted into a linear partial differential ...

A new deterministic heuristic knots placement for B-Spline approximation

open access: yesMathematics and Computers in Simulation, 2020
In this paper, we propose an adaptive knot placement algorithm for B-Spline curve approximation to dense and noisy 2D data points. The proposed algorithm is based on a heuristic rule for knot placement.

Convergence Analysis of Cubic Spline Function with Fractional Degree and Applications [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2023
In this paper, a fractional degree cubic spline scheme is proposed and analyzed for fractional order with the multi-term Riemann–Liouvile (R–L) derivatives. For the integral and fractional differential equations, we handle fractional continuity equations
