A graph-based algorithm for slicing unstructured mesh files
Process planning is an important step in additive manufacturing processes that involves the creation of a deposition toolpath from input geometry. The most commonly used input geometry file formats are in the form of unstructured triangular meshes ...

Five-axis toolpath planning for aero-integral blisk cavities
Abstract Integral blisks generally made of high-temperature alloys (such as titanium alloys) are important components in aero-engines. During machining, the tool load is large and the tool wear is serious. Because trochoidal milling can maintain a small contact angle between the tool and the workpiece during the cutting process, it is ...

Toolpath planning for CNC machining of hub surface of blisk
Abstract This paper presented a toolpath planning and generating method for machining a hub surface of a blisk. This method can be used to generate smooth and gradually changing toolpaths and avoid an undercut on hub. In this paper, the hub surface has been defined with a uθ-parametric region.
