Abstract: A method and system simulates a work process on a machine tool using a virtual machine. The virtual machine is set up to simulate the work process on the machine tool using machine data, workpiece data, and tool data as a function of numerical control (NC) control data and programmable logic control (PLC) control data. The work process is simulated on a platform that comprises a plurality of processor cores, wherein the work process is simulated in partial simulations that run in parallel on different processor cores.

Abstract: The invention relates to a device and a method for simulating a sequence for machining a workpiece on a machine tool. The invention is characterized by a holistic simulation approach. Particularly, a PLC control means 723 and a PLC sequence simulation means 725 assist in simulating the PLC movement sequences of the machine tool. This enables a realistic simulation of a machine tool in all its substantial aspects, resulting in considerable advantages especially in the field of training and during the determination of machine utilization times.

Abstract: The present invention relates to a method and apparatus for generating control data for controlling a predetermined tool on a machine tool for machining a workpiece clamped in the machine tool from a blank to a finished part. Machining geometry model data of a machining geometry of the workpiece at a machining time are compared with finished part geometry model data in order to determine a difference geometry between the machining geometry and the finished part geometry. On the basis of the determined difference geometry, a machining path is determined for the predetermined tool for removing material from the workpiece, and path data is generated such that a maximally large part of the volume of the difference geometry is removed per time unit in dependence of a maximum machining volume of the predetermined tool.
