General tool correction for five-axis milling

The International Journal of Advanced Manufacturing Technology, 1995
In this paper a method is presented by which cutter location data can be determined for any type of milling tools defined according to DIN 66215 whereby any point of the tool can be defined as the contact point. In addition, the cutter location point for 5-axis milling can be determined using a single formula for any type of milling tool.

Five-axis milling mechanics for complex free form surfaces

CIRP Annals, 2011
Accurate and fast prediction of machining forces is important in high performance cutting of free form surfaces that are commonly used in aerospace, automotive, biomedical and die/mold industries. This paper presents a novel and generalized approach for prediction of cutting forces in five-axis machining of parts with complex free form surfaces ...

Design for Manufacturing: Geometric Manufacturability Evaluation for Five-Axis Milling

Journal of Manufacturing Science and Engineering, 2021
Abstract The geometric manufacturability of a part design is an important decision factor for various manufacturing applications and is especially critical for the machining process. In machining, the geometric manufacturability is primarily determined by geometric accessibility, which has a direct impact on decisions such as setup ...

Modeling, simulation, and optimization of five-axis milling processes

The International Journal of Advanced Manufacturing Technology, 2014
The five-axis milling is widely applied to complex surface machining. When cutting forces of milling processes increase, the consequent workpiece and tool deflections may result in poor machining quality and high processing cost. There are a lot of researches on three-axis milling processes simulation, but very few about five-axis milling.

Collision-Free Five-Axis Milling of Twisted Ruled Surfaces

CIRP Annals, 1993
Summary Ruled surfaces (generated by straight ruling lines) are a special kind of free form surfaces which plays an important role, e.g., in aerodynamic surfaces (rotary engines). They are particularly well suited for five axis milling by the Bank milling method. In the case of twisted ruled surfaces, however, the obvious milling method of having the

Five-axis NC cylindrical milling of sculptured surfaces

Computer-Aided Design, 1995
In theory, the five-axis numerical control (NC) machining of sculptured surfaces can be classified into facing milling and cylindrical milling (or side milling). In general, the first one, using flat-end cutter, is suitable for the machining of large sculptured surfaces, e.g.

Evaluation of Surface Roughness in Five-Axis Ball-End Milling

Proceedings of Higher Educational Institutions. Маchine Building, 2020
Unlike three-axis machining, five-axis machining allows the end tool or workpiece to be oriented at any angle relative to the machine axis OZ. It can be achieved by changing the values of the tool tilt angle and lead angle relative to the surface normal in the contact zone of the tool surface and the workpiece, taking into account the direction of the ...

CAx Framework for Planning Five-Axis Milling Processes

2010
Given an efficient process, five-axis milling is a productive technology that can help production industries in countries with a high level of workers’ wages to remain competitive on the global market. For planning the required machining processes, engineers have to be supported by methods and tools. In current research at WZL of RWTH Aachen and IPT of

Positioning accuracy improvement in five-axis milling by post processing

International Journal of Machine Tools and Manufacture, 1997
Abstract A five-axis machine is currently one of the most versatile machine tools available. The importance of five-axis milling is easily recognizable when manufacturing moulded and sculptured surfaces; where the tool tip direction and position are controlled simultaneously.

Ball-End Cutter Machining Process Analysis in Five-Axis Milling

Applied Mechanics and Materials, 2010
In this paper, the three dimensional geometrical analysis is depicted with the interacting relations among cutting edge, undeformed chip and shear zone along cutting direction, and a general geometrical model of five-axis machining curve surface in ball-end milling is presented. A general force model is derived, and the three dimensional cutting forces
