Toolpath Optimization for High Speed Milling of Pockets

2009 Second International Conference on Information and Computing Science, 2009
In milling pocket corner, there maybe residual material left at sharp corners when stepover is extremely large in contour-parallel toolpath. This paper describes an improved pocket toolpath by inserting biarc transitions segments in contour-parallel toolpath.

Incorporating Kinematic Properties into Fused Deposition Toolpath Optimization

2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018
The most widely used methods for toolpath planning in fused deposition 3D printing slice the input model into successive 2D layers in order to construct the toolpath. Unfortunately slicing-based methods can incur a substantial amount of wasted motion (i.e., the extruder is moving while not printing), particularly when features of the model are ...

Toolpath Optimization for 3-Axis Milling of Thin-Wall Components

2020
Milling of thin-wall components often entails significant workpiece static deflections, which make manufacturers use conservative cutting parameters along the toolpath to meet the tolerance required. This paper presents a technique to define the 3-axis toolpath that maximizes cutting parameters, without compromising the accuracy of the component.

A numerical approach to optimize the toolpath strategy for polymers forming

Materials Research Proceedings, 2023
Abstract. Incremental sheet forming is a relatively new technology with a deformation strategy that resembles the layered manufacturing principle of rapid prototyping; thanks to this, it can represent a viable way to form metal and polymer sheets, guaranteeing high customization and cost-effectiveness.

Toolpath Algorithm for Complex Pocket on the Network Optimization

Advanced Materials Research, 2010
On the consideration of connection of offset contour, deletion of interferential contour loop and accurate generation of toolpath in pocket machining, the linking of the pocket toolpath is paid close attention to, and an algorithm based on network optimization for complex pocket is brought forward.

Optimized sequencing of CNC milling toolpath segments using metaheuristic algorithms

Journal of Mechanical Science and Technology, 2019
Intelligent selection of a short toolpath is made possible by reducing machining cycle time. Each metal cutting layer in a workpiece is composed of several entities, such as lines and arcs, which form the different cutting segments of a cutting plan. During machining, the cutter moves at controlled feed rates along various segments at a high speed in a

Linear programming and windowing based feedrate optimization for spline toolpaths

CIRP Annals, 2017
Abstract Optimality and computational efficiency are competing objectives in the design of feedrate optimization algorithms for spline toolpaths. This paper presents a new approach, in which the use of Linear Programming (based on the ‘pseudo-jerk’ concept) is combined with a novel windowing algorithm to handle long toolpaths.

Continuous Toolpath Optimization for Simultaneous Four‐Axis Subtractive Manufacturing

Computer Graphics Forum
AbstractSimultaneous four‐axis machining involves a cutter that moves in all degrees of freedom during carving. This strategy provides higher‐quality surface finishing compared to positional machining. However, it has not been well‐studied in research.
