Title : Physics based optimisation

Author: Philippe DENISET (CGTECH Vericut)
Presented by: Philippe DENISET (CGTECH Vericut)

Abstract:
VERICUT Force™ is a physics-based optimization method that determines the maximum reliable feed rate for a given cutting condition based on the following four factors: force on the cutter, spindle power, maximum chip thickness, and maximum allowable feed rate. It calculates ideal feed rates by analyzing tool geometry and parameters, material properties of the stock and cutting tool, detailed cutting edge geometry, and VERICUT cut-by-cut contact conditions. Force interpolates cutting conditions using a proprietary set of materials coefficients to account for the strength of material and the effects of friction and temperature. The materials data is created from actual machining tests and does not rely on extrapolating from finite element analysis results. The unique cutting coefficients used by Force result in the most accurate cutting force calculations available today.

Presented by: D. MATTHEY et M. FONTAINE

Abstract:
The increasing demand for micro-components needs to control and develop the dedicated manufacturing processes. Among existing processes, micro-milling is one of the most versatile. From a down-scaling of conventional machining, micro-milling can be defined by the use of tools with a diameter lesser than one millimeter. This leads to be applicable in a wide range of materials and for complex 3D geometry and relatively high shape ratio parts.
The market of precision metal parts such as dies and mods, medical device, luxury products, and sensors for example, is asking relevant solutions to manage micro-milling of hard metals, with high purpose of precision, tool life, and productivity. In this view, the Magafor company, international leader of center drills and specialist of precision tools and micro-tools, developed a new set of micro-mills dedicated to hard metals precision machining in collaboration with the FEMTO-ST research institute. These optimized square end and ball end micro-mills have been defined after two major projects with support of CNRS (French National Center for Scientific Research) and ANRT (French National Association for Technological Research).
This paper presents the industrial context and strategy associated to these developments, the scientific methodology used, some illustrating results and the new micro-mills set, named Optimag©. The benefits for users are commented and some recommendations of use are given. Finally, some new current developments are presented.
Keywords: Micro-milling; Hard metals; Hardened steel; End mills; Ball end mills; Optimization; Industrial strategy

The keynote paper should be published in the conference proceedings. The standard HSM conference template will be used. The page range will be slightly increased (approx. 8-10 pages)


Title: Additive manufacturing at Safran Aircraft Engines – Aircraft Engines applications - Impact of Additive Manufacturing on machining processes

Authors: Nathalie DANG, Vincent DESSOLY (SAFRAN AIRCRAFT ENGINES, FRANCE)
Presented by: Nathalie DANG (SAFRAN AIRCRAFT ENGINES, FRANCE)

Abstract:
Additive manufacturing is a major subject for Safran Aircraft Engines. In fact, the use of additive manufacturing technologies will be a key of success as it leads to the decrease the production cycle times and greater industrial flexibility.
Nevertheless, for effective of additive manufacturing technologies, finishing is a key point and even more for aircraft engine parts for which aerodynamical and mechanical properties are tough.
Safran Aircraft Engines presentation will present additive manufacturing technologies used and will give an overview of parts concerned. Then, it will go into details in its issues and its studies progress status.


Title: Workpiece fixture: important element for improving manufacturing productivity and accuracy of low rigidity components

Authors: Petr KOLAR, Hans-Christian MÖHRING, Petra WIDERKEHR, Jiri SVEDA
Presented by: Petr KOLAR (RCMT, CTU Prague - Czech Republic)

Abstract:
Workpiece fixture elements are important components which influence machining process performance and accuracy. Integral to the accuracy and force flux of the entire system between the machining process and machine tool they significantly influence process parameters value choice to improve final workpiece quality. This especially applies to machining medium- and large-sized thin-walled parts. Intelligent fixtures incorporating sensors, actuators and specific control algorithms together with advanced simulation tools are able to solve specific machining issues related to workpiece alignment, minimization of workpiece deformations and suppression of workpiece vibrations. In this paper, a general methodology for the application of intelligent fixtures is presented. Specific case studies are discussed by demonstrating the possibilities of modifying the behavior and interactions between the process and machine tool in order to reduce manufacturing time and costs as well as to improve the machining accuracy.
