Abstract: A machine tool system has a machine tool with a stationary machine base, support elements connected to the machine base, and a crossbeam connected to the support elements. The crossbeam is adjustable relative to the support elements in a Z-direction or the support elements are adjustable relative to the machine base in an X-direction. A tool holder head is mounted on the crossbeam and adjustable for travel in a Y-direction along the crossbeam. The X-, Y- and Z directions form a cartesian coordinate system. A control facility is connected to the machine tool for controlling travel in the Y-direction and adjustment in at least one of the X- and/or Z-directions based on a kinematic parameter specified as a function of a position of the tool holder head relative to the Y-axis and thus takes into account asymmetric load distribution caused by movement of the tool holder head.

Abstract: A machine tool numerical controller receives a parts program which determines a path along which a workpiece should be machined in a material-removing manner by a machining tool. The numerical controller determines control commands by utilising the parts program and controls the position-controlled axes according to the determined control commands. The numerical controller determines the control commands such that the workpiece is machined in a material-removing manner by the machining tool along the path determined by the parts program. During the machining of the workpiece, the numerical controller receives, in real time, actual values characteristic of a machining force exerted on the machining tool and takes a geometrical measurement of the machining tool and the machining force into consideration in the determining of the control commands. During the machining process, the geometrical measurement is varied dynamically and in real time according to the machining force.

Abstract: In a method for operating a machine having a trajectory determined by a parts program and including multiple block transitions with a non-tangential contour, a high trajectory speed and a short operating time are achieved. For a first position-controlled axis, an acceleration duration different from a first period duration can be specified, wherein a transition maximum speed for the first position-controlled axis is determined such that, when the first position-controlled axis moves with the transition maximum speed and the transition maximum acceleration is applied, the speed of the first position-controlled axis has a value of zero at the end of the acceleration duration. The traversing movement is determined such that the speed of the first position-controlled axis, at the transition from a first trajectory section to a second trajectory section, does not exceed the transition maximum speed.

A processing result of the first workpiece (5a, 5b) at an end of the first tool track is the same as a processing result of the second workpiece (5a, 5b) at an end of the second tool track.

Abstract: In a method for operating an at least two-axle machine tool, a geometric description of a path is specified, and according to the path, an advancing movement is carried out by simultaneously moving at least in one section a first axle and a second axle. A first maximum value for a first kinematic parameter relating to the advancing movement along the section of the path is defined by a control unit based on the geometric description. The advancing movement along the section is planned by the control unit by taking the first maximum value into consideration, and the axles are actuated so as to carry out the advancing movement according to the planned movement.

Abstract: A system program monitors a numerical controller executing a useful program controlling a machine. The numerical controller determines target values for position-controlled axes and controls the position-controlled axes in accordance with the target values. The numerical controller stores resources and determines whether, and optionally to which extent, the resources are enabled or disabled. Enabling or disabling the resources specifies how many processor cores are enabled for use, or how many processor threads are enabled for use, or to what extent a processor cache or a processor main memory are enabled for use, or which hardware components of the numerical controller are enabled for use, or to what extent use of external computing power is permitted. The numerical controller determines the target values for the position-controlled axes using only the enabled resources.

Abstract: In a method for severing a solid body, a defined contour is stored in a control unit configured to detect contour breaches and to avoid contour breaches. A high-energy beam is moved along a contour on a surface of the solid body, with the surface of the solid body facing the high-energy beam, to produce with the high-energy beam a cutting gap. The contour on the surface is compared with the defined contour stored in the control unit, and avoidance of the contour breach is automatically deactivated when the contour on the surface of the solid body matches the defined contour and a contour breach is detected. Otherwise, the contour is omitted. Advantageously, the high-energy beam travels along the contour with an averaged line movement.

Abstract: A numerically controlled machine tool has at least one movement axis and is connected to a numerical controller which includes a parts program. Movements of each movement axis are limited by maximum permissible axis dynamics. The parts program has a sequence of instructions for machining a workpiece which specify different maximum desired speeds for the machining of the workpiece which change abruptly over time. The numerical controller approximates the different maximum desired speeds which change abruptly over time with a desired speed profile that is continuous over time and has a profile of the maximum desired speeds which is also continuous over time. The numerical controller uses the continuous desired speed profile to calculate the desired values of an actual movement profile of the movements for each movement axis.

Abstract: A numerically controlled production system is connected to a numerical controller, which includes a control program with successive program sets, and a look-ahead module which determines therefrom for successive clock-cycle points a movement profile with guidance variables for a movement axis prior to a movement. Subject to a condition, the control program includes program branching with multiple alternative control program sections, and determines which of the alternative control program sections is to be additionally executed subject to the condition. The look-ahead module calculates and stores an alternative movement profile for each alternative control program section prior to an additional movement, and holds the alternative movement profile available for the conditional program branching in order to carry out the additional movement.

Abstract: In a method for 3D radius correction in CNC milling, a mill path of an original milling tool producing a surface contour on a workpiece is calculated for an original milling tool based on dimensions of the mill cutter tip, with the positions of the mill cutter tip specified by an NC program. A surface normal of an end face milling surface and a surface normal of a circumferential milling surface are then specified, for each position of the mill cutter tip taking into account dimensional differences between an actually available milling tool and the original milling tool. By specifying along the mill path a spatial orientation of the milling tool axis, a correction vector is specified from the milling tool orientation, dimensional differences and the surface normals, and the workpiece is machined by traversing the mill path with the actual milling tool under consideration of the correction vector.
