Optimal toolpath planning strategy prediction using machine learning technique
Engineering Applications of Artificial Intelligence, 2022 Abstract Finding the best toolpath planning strategy for Computer Numerical Control (CNC) machining requires a trial-and-error approach. One needs to follow a number of steps, viz., generate the toolpath, perform simulations/machining, measure various parameters to quantify the quality of the toolpath, and then select the best toolpath.

Efficient toolpath planning for collaborative material extrusion machines
Rapid Prototyping Journal, 2023 Purpose Timing constraints affect the manufacturing of traditional large-scale components through the material extrusion technique. Thus, researchers are exploring using many independent and collaborative heads that may work on the same part simultaneously while still producing an appealing final product.

Toolpath Planning for Manufacturing of Complex Parts Through Incremental Sheet Forming [PDF]
ASME Open Journal of Engineering, 2022 Abstract Incremental sheet forming (ISF) offers great flexibility in producing complex sheet parts as compared with conventional sheet forming processes where part-specific die sets are required to form a product. While there are many potential applications of ISF in various industries, toolpath planning for multifeature parts remains a ...
