dc.description.abstract
Increasingly integrated systems and the use of innovative lightweight structures enabled an evolution of the machine tool industry to products with very high dynamic performance and precision. For the development of modern machine tools, simulation has continuously gained in importance. However, due to increasing pressure to reduce the time-to-market of new products, an efficient work-flow for the integration of simulation in the design process is crucial. In this contribution, a newly developed design process named Design to Specifications (DtS) is presented. DtS places the focus on productivity and accuracy specifications for a machine tool and enables the design of structures that precisely meet the specifications. In a first step, requirements on structural properties are regarded. The requirements on dynamic capabilities as jerk or acceleration limitations are derived from productivity specifications, using computer aided manufacturing tools, and reference workpieces of choice. From requirements on dynamics and accuracy specifications, the required position controller bandwidth is derived, from which a minimum critical system eigenfrequency is deduced that allows a design engineer to select machine parts and to estimate proper dimensions for critical components. After having designed a particular structure, a virtual prototype is created that allows a time-saving verification of the dynamic capabilities of a machine tool by means of calculations in frequency domain. The calculation of maximum contour errors by means of weighted frequency response functions of the dynamic tracking error is presented. In summary, DtS enables an efficient design or modification of machine tool structures using an effective application of control theory estimations and verification using virtual prototypes.
