Tool path generation for a surface model with defects
Computers in Industry, 2010A 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
CAD Computer Aided Design, 2003For 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.

Tool-path generation for sidewall machining
Computers & Industrial Engineering, 2009Presented 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, 2013In 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., 2004In 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 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.

Tool-path generation from measured data
Computer-Aided Design, 2003Presented in the paper is a procedure through which 3-axis NC tool-paths (for roughing and finishing) can be directly generated from measured data (a set of point sequence curves). The rough machining is performed by machining volumes of material in a slice-by-slice manner.

The Implementation of Tool Path Generation for the Robot Application
2018 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2018With the widespread use of the industrial robots, the offline programming (OLP) is becoming increasingly important for the robot programming. Currently, online programming is the most common programming method, however, it is always time-consuming and expensive for the complex applications such as machining, painting and welding.

The Geometry and Generation of NC Tool Paths
Journal of Mechanical Design, 1996Numerically 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.
