Automatic cutter selection and optimal cutter path generation for prismatic parts

International Journal of Production Research, 1991
Abstract 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.

CNC Cutter Path Generation in Shape Deposition Manufacturing

Concurrent Product and Process Engineering, 1995
Abstract Shape Deposition Manufacturing is a layered manufacturing process which attempts to build functional parts by incremental material deposition and fusion of three-dimensional layers. Five-axis CNC machining is employed in Shape Deposition Manufacturing to machine the layers to the net shape.

Generation of gouge-free cutter location paths on freeform surfaces for non-spherical cutters

Computers in Industry, 1996
Abstract 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 ...

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, 1998
A 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

Hybrid Cutter Path Generation for 2.5D Milling Operation

Volume 1: 22nd Computers and Information in Engineering Conference, 2002
2.5D milling operation is widely used in a variety of applications. Generating efficient cutter path for 2.5D milling operation is very important in order to shorten total machining time and thus enhance overall throughput. However, most existing cutter path generation algorithms do not produce highly efficient cutter paths for certain type of complex ...

Three-axis NC cutter path generation for subdivision surface

Geometric Modeling and Processing, 2004. Proceedings, 2004
In 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.

Cutter path simulation and product visualization using AutoCAD

Computer Applications in Engineering Education, 2000
In 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 ...

A new cutter path construction technique for milling machines

International Journal of Production Research, 1995
This 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 ...

Elliptical torus cutter tool path generation based on minimum distance computation

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021
In mould manufacture the elliptical torus cutters are used for their high cutting velocity, but the special geometry also brings issues in tool path generating and machining quality controlling. In this paper a guide curve tool path generating method for elliptical torus cutters is presented with the cutter location points computed by a minimum ...

Generation of Five-Axis Cutter Paths for Turbomachinery Components

Journal of Engineering for Gas Turbines and Power, 1999
A simple, yet useful algorithm is developed to generate tool paths with global interference checking for five-axis point milling of turbomachinery components. 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 be detected.
