Toolpath Planning and Generation for Multi-Stage Incremental Forming Based on Stretching Angle. [PDF]

Materials (Basel), 2021
To solve the problems that exist in the multi-stage forming of the straight wall parts, such as the sheet fracture, uneven thickness distribution, and the stepped feature sinking, a new forming toolpath planning and generation method for the multi-stage incremental forming was proposed based on the stretching angle.

Optimal Realtime Toolpath Planning for Industrial Robots with Sparse Sensing

Actuators
Non-contact surface processing does not involve direct contact between the tool and a worksurface. An industrial robot mostly uses preplanned toolpaths to perform non-contact surface processing.

Local corner smoothing based on deep learning for CNC machine tools [PDF]

Scientific Reports
Most of toolpaths for machining is composed of series of short linear segments (G01 command), which limits the feedrate and machining quality. To generate a smooth machining path, a new optimization strategy is proposed to optimize the toolpath at the ...

Coordinated Toolpath Planning for Multi-Extruder Additive Manufacturing [PDF]

2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2021
We present a new algorithm for coordinating the motion of multiple extruders to increase throughput in fused filament fabrication (FFF)/fused deposition modelling (FDM) additive manufacturing. Platforms based on FFF are commonly available and advantageous to several industries, but are limited by slow fabrication time and could be could be ...
