Tool-path generation for finishing
1998The 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).

Tool path generation for NC grinding
International Journal of Machine Tools and Manufacture, 1998A new method for tool path generation for grinding is proposed. This method for tool path generation is based on a conceptually simple yet fundamental representation of the manufactured surface. Such representations of the manufactured surface, which are derived analytically, were traditionally derived by measurement based methods.

Tool-path generation for roughing
1998Presented 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 ...

A Generic Tool Path Generation Methodology for Incremental Forming
ASME 2008 International Manufacturing Science and Engineering Conference, Volume 1, 2008This paper presents a generic methodology for tool path generation for an arbitrary component that can be formed by single point incremental forming (SPIF) to obtain required geometrical accuracy. Adaptive slicing concepts used in layered manufacturing have been modified and used for generating tool path for SPIF.

A tool for automatic generation of self-checking data paths
Proceedings 13th IEEE VLSI Test Symposium, 2002An important drawback of implementing self-checking circuits concerns the lack of dedicated CAD tools. This problem results on a significant increasing of the design effort and compromises the interest of such designs. CAD tools aimed to implement self-checking data paths is of high interest since data-paths are basic parts of microprocessors and ...

Tool Path Generation for Turbine Blades Machining With Twin Tool
Journal of Manufacturing Science and Engineering, 2017Blades are essential parts used in thermal and nuclear power generation. Its machining precision is a vital factor that influences the efficiency and life of those industries. Blades are thin-walled parts, which could easily deform under cutting forces, and hence deteriorate the machining precision.

An adaptive tool path generation algorithm for precision surface machining
Computer-Aided Design, 1998Abstract In this paper an adaptive CNC tool path generation algorithm for precision machining of parts with free-form surfaces is proposed. It is aimed at developing a generic CNC tool path generation methodology suitable for machining parts having analytical curves/surfaces and/or sculptured (parametric) surfaces, as opposed to most ...

Fundamentals of tool-path generation and validation
1998The purpose of this chapter is to provide an overview of tool-path generation and validation for sculptured surface machining (SSM). Major topics to be discussed in this chapter include: (1) issues in planning tool-path topology and selecting milling-strategy options, (2) tool-path resolution planning, (3) CL-data computation, (4) cutter-interference ...

Curvilinear tool path generation for pocket machining
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2011In this paper, a curvilinear tool path generation method with implicit moving boundaries is presented for pocket machining. The pocket profile is implicitly embedded into a higher-dimensional function, namely the level set function, and is represented with the zero level set as a moving boundary.

Introduction to tool-path generation methods
1998As an introduction to Part Two, this chapter provides a comprehensive review of the ‘conventional’ tool-path generation methods and proposes a new tool-path generation method called the ‘C-space method’. The conventional methods to be covered in this chapter are isoparametric methods, Cartesian methods and APT-type methods.
