Force Modeling of Five-Axis Microball-End Milling
Journal of Micro and Nano-Manufacturing, 2015This paper presents a five-axis ball-end milling force model that is specifically tailored to microscale machining. A composite cutting force is generated by combining two force contributions from a shearing/ploughing slip-line (SL) field model and a quasi-static indentation (ID) model. To fully capture the features of microscale five-axis machining, a

Volume 3: Design and Manufacturing, 2007
This paper presents optimization schemes for the five-axis flank milling of jet engine impellers based on the mechanics model explained in Part I. The process is optimized by varying the feed automatically as the tool-workpiece engagements, i.e. the process, varies along the tool path.

Five-axis Trochoidal Flank Milling of Deep 3D Cavities
Computer-Aided Design, 2020Abstract Trochoidal milling is widely used in slotting and pocketing operation owing to its unique cyclic pattern that restricts the tool-workpiece engagement and hence reduces the cutting force load and helps heat dissipation. Especially when cutting extremely hard materials such as super titanium alloy, trochoidal tool path has been a good milling ...

Modeling regenerative workpiece vibrations in five-axis milling
Production Engineering, 2008During milling—especially of thin-walled components—the dynamic behavior of the workpiece-tool-machine-system influences the milling process and particularly the quality of the resulting workpiece surface. This article focuses on the presentation of a simulation concept for predicting regenerative workpiece vibrations, which combines a finite element ...

Analytical model of milling forces prediction in five-axis milling process
The International Journal of Advanced Manufacturing Technology, 2020In the process of the five-axis milling process, due to the changing of the cutter-workpiece engagement area and instantaneous uncut chip thickness, five-axis milling forces prediction is difficult compared with three-axis forces prediction. This study proposed a new analytical method to predict milling force in five-axis milling.

VERNE - a five-axis parallel kinematics milling machine
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2005Ten years ago a new kind of machine tool was presented in Chicago, based on parallel kinematics architectures. Since then, many of these parallel kinematics machines (PKMs) have been developed around the world. Their main interest lies in their high dynamic characteristics, which could help in going faster in high-speed milling.

Cutter Axis Vector Smoothing Algorithm for Five-axis Milling
2019 IEEE 2nd International Conference on Automation, Electronics and Electrical Engineering (AUTEEE), 2019In the five-axis milling process, the existing cutter axis vector planning only adjusts the cutter axis vector and neglects the effect on the cutting bandwidth. Considering this problem, a method of adjusting the cutter axis vector by contrasting the change rate of the cutter axis vector is proposed, which not only ensures the cutting bandwidth but ...

High-speed five-axis milling of hardened tool steel
International Journal of Machine Tools and Manufacture, 2000This paper investigates critical issues related to high-speed five-axis milling of hardened D2 tool steel (hardness HRc 63). A forging die cavity was designed to represent the typical features in dies and molds and to simulate several effects resulting from complex tool path generation.
