Tool path generation for a surface model with defects

Computers in Industry, 2010
A 3-axis tool path generation algorithm for free-form surface models including defects, such as gaps and overlaps is presented in this paper. To avoid the difficulty of computing a complete cutter location (CL)-surface, the proposed approach generates a tool path by slicing CL-elements instead of a complete CL-surface.

Tool-path generation for Z -constant contour machining

Computer-Aided Design, 2003
For the Z-constant contour machining, a tool-path generation procedure is presented. The suggested procedure consists of two parts; (1) calculating the contours (tool-path-elements) by slicing the CL-surface with horizontal planes and (2) generating a tool-path by linking the contours.

Layer Based Micro-Machining—New Approach for Tool-Path Generation

CIRP Journal of Manufacturing Science and Technology, 2011
This paper proposes a new tool-path generation approach for layer-based micro machining (“conventional”, laser or EDM milling). With this approach, the laser spot non-conformity or EDM tool wear is compensated for by varying the layer machining angle and

Efficiency-Optimal Iso-Planar Tool Path Generation for Five-Axis Finishing Machining of Freeform Surfaces

CAD Computer Aided Design, 2017
Traditional works in five-axis iso-planar tool path generation mainly aim at finding the best direction of the parallel drive planes so that the total length of the tool path is minimized.

Mesh-Based Tool Path Generation for Constant Scallop-Height Machining

International Journal of Advanced Manufacturing Technology, 2008
This paper presents a new approach to mesh-based tool path generation for obtaining constant scallop heights. The mesh surface has recently become the focus of considerable interest, because its geometric computation is simpler and more robust than that ...

Tool-path generation for sidewall machining

Computers & Industrial Engineering, 2009
Presented in this paper is a tool-path generation procedure for sidewall machining, a process that is essential in the fabrication of many mechanical parts. While sculptured surface machining has received a significant amount of attention, there has been relatively less study of the technological requirements of sidewall machining. In this paper, three

Tool path generation for algebraically parameterized surface

Journal of Intelligent Manufacturing, 2013
In CAD/CAM integrated environment, parametrically defined free-form surfaces may require to be truncated to suit the profile of an object to be machined. In such a case the truncated surface needs to be parameterized anew according to the boundaries.

Tool-path generation for NURBS surface machining

Proceedings of the 2003 American Control Conference, 2003., 2004
In CAD systems, a surface to be machined is expressed by a series of curves, such as B-spline, Bezier and NURBS curves, which compose the surface and then in CAM systems the curves are divided into a large number of line or arc segments. These divided movement commands, however, cause many problems including their excessive size of NC data that makes ...

Tool-path generation for roughing

1998
Presented in this chapter are C-space based tool-path generation methods for roughing, with a special emphasis on pocket machining. Topics to be discussed are (1) characteristics of roughing operations, (2) CL-surface construction for roughing, (3) tool-path generation for pocket-machining, (4) 2D offsetting for CPO tool-path generation, (5) handling ...

Tool-path generation for finishing

1998
The purpose of a finishing operation in an SSM-process is to generate a smooth surface ‘region’, and as a result, finish-machining is often called regional milling. Thus, we will use the term ‘regional milling’ to refer to finish-machining (as well as semi-finishing).
