Tool Path Generation for Flexible Blade Cutting
2000Free Form Thick Layered Object Manufacturing FF-TLOM is based on application of a reshapeable cutting device, which allows a free form shaping of thick polystyrene foam layers. Once manufactured, these layers are stacked to produce a physical model. Tool path generation for the heated flexible blade tool is a challenging task, since it influences the ...

Tool Path Generation Based on B-Spline Wavelets
Volume 2B: 27th Design Automation Conference, 2001Abstract Tool path generation is a fundamental problem in numerical control machining. Typical methods used for machining 2.5D objects include generation of offset contours using trimmed offset curves and zigzag sequences. The offset contours result in unnecessary detailed curves far away from the object boundary.

Tool-path generation of planar NURBS curves
Robotics and Computer-Integrated Manufacturing, 2010It has been widely used in CAD field for many years and gradually applied in CAM area with the prevalence of NURBS interpolator equipped in CNC controllers. But few of them provide the tool radius compensation function. In order to achieve the goal of generating tool-path, an algorithm was presented to offset NURBS curves by an optimum process for CAD ...

Tool Path Generation for Arbitrary Pockets with Islands
Journal of Intelligent Manufacturing, 2006Avoiding gouge is crucial when converting cutter contact (CC) data into cutter location (CL) data for arbitrary pockets involving islands. This investigation presents a dynamic method for eliminating global gouges. Moreover, this study proposes using pair-wise bridges to merge pockets and islands.

Flexible Tool-path Generation for Variable Geometry
2011Assembled components often exhibit slight geometric variations from CAD nominal positions. In such cases, there is a desire to retain the expert knowledge of experienced manufacturing engineers using advanced CAM tool path planning software, while enabling adjustment of the tool paths to accommodate the actual measured assembly geometry.

Tool Path Generation for Machining Shrouded Turbine Blisk
Manufacturing Engineering and Materials Handling Engineering, 2004Shrouded turbine blisk is an important component for liquid-propellant rocket engine, airplane engine and some other high-power turbine machines. It is made from high-temperature alloy (e.g., nickel-base alloy and titanium alloy) and hence, is difficult to machine. In addition, its geometrical shape is complicated involving many semi-enclosed, twisted,

Direct tool-path generation from massive point input
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2002The paper presents an algorithm and methodologies for the direct numerical control (NC) cutter path generation from a point cloud. Different from the existing approach, it will generate the cutter path without any reconstruction of the surface patch.

Raster milling tool‐path generation from STL files
Rapid Prototyping Journal, 2006PurposeThis paper presents an offset‐based tool path generation method for STL format three‐dimensional (3D) models. The created tool‐paths can be effectively used to near‐net‐shaped parts, in particular those created using rapid prototyping.Design/methodology/approachThe STL model is first offset by the distance of the selected cutter radius using a ...
