A study of the effects of cutter path strategies and orientations in milling
Journal of Materials Processing Technology, 2004Abstract The implementation and selection of cutter path strategies and orientations when milling is particularly critical in the aerospace and mould and die industries. Proper selection can lead to substantial savings in machining time, improvement of workpiece surface quality and improvement in tool life, thereby leading to overall cost reduction ...

Global optimization of tool path for five-axis flank milling with a conical cutter
CAD Computer Aided Design, 2010In this paper, optimum positioning of the conical cutter for five-axis flank milling of slender surfaces is addressed from the perspective of approximating the tool envelope surface to the data points on the design surface following the minimum zone criterion recommended by ANSI and ISO standards for tolerance evaluation.

Cutter path generation for 2.5D milling by combining multiple different cutter path patterns
International Journal of Production Research, 2004Different cutter path patterns have been shown to be efficient for different types of pocket geometries. However, for certain types of complex pockets, no single type of pattern produces efficient cutter paths throughout the pocket. In this paper, different cutter path patterns are systematically analysed, and several existing heuristics for selecting ...

Automatic cutter selection and optimal cutter path generation for prismatic parts
International Journal of Production Research, 1991Abstract NC code generation, if done manually, forms the bottleneck in a production system. Hence automatic NC code generation forms an important part of a totally automated manufacturing system. Most of the existing systems for this task consider cutter path generation only for limited part geometry.

Generation of Five-Axis Cutter Paths for a Ball-End Cutter With Global Interference Checking
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education, 1998A simple, yet useful procedure is developed to generate tool paths with global interference checking for five-axis machining of turbomachinery components with complex geometries. Based on the projected distance between the surface data and the cutter-axis of a cylindrical ball-end mill, interference between the surface of a workpiece and the cutter can

Cutter path simulation and product visualization using AutoCAD
Computer Applications in Engineering Education, 2000In this paper, a software tool for NC (numerical control) cutter path simulation and product visualization, 3D-Sim, is presented. 3D-Sim utilizes a commercial computer-aided design (CAD) software tool, AutoCAD, to perform virtual NC verification. An NC program is interpreted and transformed into an AutoLISP program, which once loaded in AutoCAD allows ...

Generation of gouge-free cutter location paths on freeform surfaces for non-spherical cutters
Computers in Industry, 1996Abstract The 3-dimensional surface of automobile body panel dies, ship propellers, as well as turbine blades and plastic dies is almost always composed of freeform (or sculptured) surfaces. The generation of a gouge-free cutter location (CL) path on freeform surfaces for non-spherical cutters is a difficulty with which technicians and researchers ...

Three-axis NC cutter path generation for subdivision surface
Geometric Modeling and Processing, 2004. Proceedings, 2004In this paper we propose methodologies and algorithms of NC cutter path generation for subdivision surfaces. We select Loop surface as the subdivision surface. A path plan including rough cut and finish-cut is developed based on LoD (level of detail) property of the subdivision surface.

A new cutter path construction technique for milling machines
International Journal of Production Research, 1995This paper introduces a new method for generating cutter paths for milling machines. The generation of cutter paths is an important area for research, since it is critical to the validity of the path and efficiency of its production. In this paper, we show a mechanism by which paths may be de-constructed from initial paths, thus guaranteeing the ...
