Volume 3: Design and Manufacturing, 2007
Jet engine impeller blades are flank-milled with tapered, helical, ball-end mills on five-axis machining centers. The impellers are made from difficult-to-cut titanium or nickel alloys, and the blades must be machined within tight tolerances. As a consequence, deflections of the tool and flexible workpiece can jeopardize the precision of the impellers ...

CAx Framework for Planning Five-Axis Milling Processes
2010Given 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

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.

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

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.
