  • Publication number: 20220088735
    Abstract: In order to be able to take into account machining configurations more flexibly, a method for optimizing numerically controlled machining of a workpiece includes ascertaining geometric interaction data. A relationship between a force to be expected and a configuration parameter of the machining is determined on the basis of the interaction data. The force is calculated during the machining on the basis of the relationship and a current value of the at least one configuration parameter. The machining is adapted depending on the calculated force.

  • Publication number: 20190325270
    Abstract: Provided is a method for determining a physical shape having a predefined physical target property that includes calculating a sensitivity landscape on the basis of a shape data record for the physical shape with the aid of a calculation device. The calculation device is a machine-taught artificial intelligence device. The shape data record identifies locations at or on the physical shape. For a plurality of these locations, the sensitivity landscape respectively indicates how the target property of the physical shape changes if the physical shape changes in the region of the location. Furthermore, the shape data record for the physical shape to be determined is changed on the basis of the sensitivity landscape in such a manner that the predefined physical target property is improved.

  • Publication number: 20190137974
    Abstract: Design data are input for an object to be additively manufactured and to be optimised in terms of a physical optimisation target is provided. A volumetric model of the object is initialised with a material distribution according to the design data, the volumetric model having a plurality of volume elements. A respective local target property relating to the optimisation target is then determined for volume elements of the volumetric model, based on the material distribution. According to embodiments of the invention, each volume element is checked to determine whether the volume element is supported in terms of additive manufacturing. Based on this, the target property of this volume element is modified in such a way that it approaches the target property if it is supported and/or moves away from the optimisation target if it is not supported.
