Tool Path Generation for Arbitrary Pockets with Islands

Journal of Intelligent Manufacturing, 2006
Avoiding 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

2011
Assembled 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, 2004
Shrouded 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, 2002
The 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, 2006
PurposeThis 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 ...

Adaptive tool-path generation on point-sampled surfaces

Precision Engineering, 2011
Abstract In this paper, we present a new approach to generate tool paths for machining point sampled surfaces using a direct projection algorithm, which is based on generating tool paths along planar intersection curves. In our implementation, a guide surface, with simple geometry like planes or cylinder surfaces, is first created according to the ...

The Geometry and Generation of NC Tool Paths

Journal of Mechanical Design, 1996
Numerically controlled milling is the primary method for generating complex die surfaces. These complex surfaces are generated by a milling cutter which removes material as it traces out pre-specified tool paths. The accuracy of tool paths directly affects the accuracy of the manufactured surface.
