    摘要: A shape data creating apparatus for creating shape data by utilizing a database has an operation measures database. The operation measures database stores attributes of working accuracy, reliability and working cost in a unit of operation of working or assembling. A shape operation measures selecting unit selects a measure used for practical work from a plurality of measure possibly used for working and assembling. A totaling unit calculates workability, assembling efficiency and cost of a shape when working measure and assembling measure selected by consulting attributes stored in the operation measures database are used. A process database stores operation processes of working and assembling. Addition, deletion and order change in an operation process are processed by a shape operation process editing unit.

    摘要: A method of correcting measurement errors in a measurement robot resulting from relative movements between an object to be measured and a measurement probe comprises the steps of detecting the accelerations at the probe, detecting the accelerations at or close to the object to be measured, calculating the correction data reproducing the relative movement from the measured accelerations and correcting the measured values recorded by the measurement robot with the correction data. The robot serves for determining shape and/or coordinates of an object to be measured, with a base unit, at least one movable measurement probe arranged on the base unit and a holding device arranged on the base unit for holding the object to be measured, wherein first acceleration are arranged on or close to the measurement probe, and second acceleration pickups are provided on the base unit, and an evaluation device is provided which calculates correction data from the measured data of the first and second acceleration pickups.

    摘要: A method for checking the buildability of a virtual prototype includes an automatic ascertainment of possible problem points that may arise in the course of assembling the virtual prototype from virtual components and do not satisfy predetermined structural, physical and/or aesthetic requirements. The method includes an assessment, assisted by a computer system, of at least one of the possible problem points as a critical or uncritical problem point, depending on several structural, physical and/or aesthetic features of the respective possible problem point. Furthermore, an apparatus is proposed for checking the buildability of a virtual prototype. With methods and apparatuses according to exemplary embodiments, the effort in terms labour and time and also faulty assessments are capable of being reduced by an automatic assessment of problem points and by a more efficient assessment of problem points.
