Virtual workpiece: workpiece representation for material removal process

The International Journal of Advanced Manufacturing Technology, 2011
In this paper, an efficient methodology to generate a virtual workpiece (VWP) is presented. VWP is a workpiece in a virtual environment in which the geometric, kinematic, and thermo-mechanical effects of the process and resources can be reflected. VWP encompasses not only the macro-information corresponding to the shape of the “virtually” machined ...

Process parallel simulation of workpiece temperatures using sensory workpieces

CIRP Journal of Manufacturing Science and Technology, 2018
Abstract Process induced heat causes workpiece shape deviations during machining and may result in rejected parts. As unpredictable processing and boundary conditions cannot be simulated in the process planning phase, a process parallel simulation of the workpiece temperature is required to observe and compensate thermal effects.

WORKPIECE CARRIER

2009
A plurality of discs (7) arranged along a central shaft and having holders (8) uniformly distributed over the circumference, inclined obliquely outwards and intended for workpieces are supported in each case on a ring (5) surrounding the discs (7). The successive rings (5) form an approximately cylindrical cladding which prevents undesired coating of ...

Tolerance Control in Workpiece Fixturing

Volume 4: 4th Design for Manufacturing Conference, 1999
Abstract When designing parts with tight tolerances, care must be paid to ensure that specified accuracy can be yielded despite manufacturing deviations. An issue to be considered is how deviations on datum elements propagate on toleranced features, taking into account configuration of locating fixtures used in manufacturing set-ups. The

Stable Workpiece Fixturing

20th Design Automation Conference: Volume 2 — Robust Design Applications; Decomposition and Design Optimization; Optimization Tools and Applications, 1994
Abstract In this paper, we present the spatial and planar force-displacement relationships which characterize individual contacts on a fixtured workpiece. The compliance at each contact is modeled and expressions for the changes in contact forces as a function of the rigid body relative motion between the fixture elements and the ...

Machining of Magnesium Workpieces

Advanced Engineering Materials, 1999
Cutting tools coated with polycrystalline diamond (DP) show a superior behavior in dry machining of magnesium alloys compared to uncoated or TiN-coated cermented carbide tools. With their usage one can best avoid adhesion between cutting tool and workpiece material as well as material build-up.

The Workpiece Material in Machining

The International Journal of Advanced Manufacturing Technology, 1999
From forming operations, it is known that the fracture strain under different stress conditions can be predicted by using ductility curves. These curves can be determined easily by two simple material tests. It will be shown that these curves can also be used to understand chip breaking.

Sensorische Werkstücke*/Sensory workpieces - Process monitoring by sensor integration into the workpiece

wt Werkstattstechnik online, 2016
In Werkzeugmaschinen eingebettete Sensorsysteme sind ein zentrales Forschungsthema der Industrie 4.0. Vor allem Sensoren in prozessnahen Maschinenkomponenten weisen eine hohe Sensitivität gegenüber den Prozesseinflüssen auf. Es liegt somit nahe, das Werkstück – Fokus jeder Produktion – als Informationsquelle zu nutzen.
