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

Robust and efficient tool path generation for machining low-quality triangular mesh surfaces

International Journal of Production Research, 2020
This paper presents a new method to generate iso-scallop tool paths for triangular mesh surfaces. With the popularity of 3D scanning techniques, scanning-derived mesh surfaces have seen a significant increase in their application to machining.

Tool path generation for NC grinding

International Journal of Machine Tools and Manufacture, 1998
A 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.

Spiral tool path generation method in a NURBS parameter space for the ultra-precision diamond turning of freeform surfaces

, 2020
Spiral tool path generation methods for the ultra-precision diamond turning of freeform surfaces can significantly affect machining efficiency and surface quality. However, effective methods for freeform surfaces with a high slope, especially nonrotation

Tool-path generation from measured data

Computer-Aided Design, 2003
Presented 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.

A Generic Tool Path Generation Methodology for Incremental Forming

ASME 2008 International Manufacturing Science and Engineering Conference, Volume 1, 2008
This 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.

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 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 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).
