Generation of Cutter Paths for Hard Material in Wire EDM

Journal of Materials Processing Technology, 2008
Abstract A heuristic method for generating a cutter path for superhard material is presented. The cutter path should satisfy various constraints that come from physical reality in industry; for example, a constraint about undesired projections of the cut-off pieces, and that about vibration and deformation generated by the cutter.

A Study of the Effects of Cutter Path Strategies and Orientations in Milling

Journal of Materials Processing Technology, 2004
Abstract 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 ...

Cutter Path Strategies for Shoulder Milling of Thin Deflecting Walls

Advanced Materials Research, 2014
The main problem associate with the machining of thin-wall component is the wall deflection which resulting in dimensional surface error that leads to part rejection. The magnitude of wall deflection is induced by the cutting force generated during the material removal process which is governed mainly from the selection of cutter path strategies ...

Cutter Path Optimization during High-Speed Machining of Numerical Control

Advanced Materials Research, 2011
During the high-speed machining, cutter path of numerical control needs to satisfy the following requirements. There has no colliding among work pieces, fixtures and so on. The cutter path variation cannot too dramatically and the vibration should in the controlled area during the process. Feed speed can modify with path curvature variation and cutting

Cutting path generation of linear hotwire cutter for VLM-ST

The International Journal of Advanced Manufacturing Technology, 2006
Most rapid prototyping (RP) processes adopt a solid CAD model, which will be sliced into thin layers of constant thickness in the building direction. Each cross-sectional layer is successively deposited and, simultaneously, bonded onto the previous layer; eventually, the stacked layers form a physical part of the model.

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.

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 ...

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

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 ...
