Abstract: An operating facility for a CNC control system controls a machine tool with a plurality of machine axes. A tool inserted into a tool receptacle of a tool spindle can be displaced relative to a workpiece and/or rotated about a tool spindle axis. A rotary controller manually operated by an operator can set a feed rate with which the tool is moved relative to the workpiece and/or a spindle rotary speed. A graphical user interface is used to adjust the effect of an operating action carried out by the rotary controller on the feed rate or the spindle rotary speed. This improves the flexibility with regard to adaptation to the requirements of the individual user.

Abstract: A control device of a production machine receives a present path and a movement command from an operator during manual operation of the production machine. An element of the production machine should be moved along the present path by means of position-controlled axes. Based on the movement command, a series of position setpoint values having a setpoint velocity is determined for the axes. The control device determines from the position setpoint values and corresponding position actual values control commands for the drives driving the axes and controls the drives accordingly. The determined control commands limit a contact force (F), which the at least one element exerts on its environment, to a force limit value (F0) specified to the control device. The control device monitors a following error of the drives and suppresses further movement of the element when the following error reaches a maximum value.

Abstract: In a method for producing and/or machining a non-conical face of a workpiece defined by a segment of a cone, in particular a sealing face of a multiple-eccentric shut-off valve, using a machine tool having at least two linear axes and at least one rotary axis controlled by a numerical controller for generating a relative movement between a tool and the workpiece, a cycle is provided on the numerical controller and retrieved by a user of the machine tool. The user parameterizes the cycle, whereafter a part program is generated by the cycle for execution by the numerical controller. The executed part program generates the relative movement along a path determined by the part program to produce and/or machine the face of the workpiece.

Abstract: A numerical controller executes a system program. While executing the system program, the numerical controller executes a sub-program. On the basis of the execution of the sub-program, the numerical controller controls position-controlled shafts of a machine tool controlled by the numerical controller. The sub-program contains instruction sets which are retrieved sequentially one after the other by the numerical controller. The numerical controller only executes the retrieved instruction sets when the instruction sets comply with permitted boundary conditions. Otherwise, the instruction sets are not executed. Before executing the sub-program and while executing the system program, the numerical controller receives information defining the permitted boundary conditions via an interface protected from unauthorized access.

Abstract: A machine tool includes a machine control unit to output control signals to drives for machine elements. A tool which machines a workpiece is thereby moved relative to the workpiece in a position-controlled manner. Arranged in a first region of one machine element is an active vibration damper to damp vibration in a second region of the machine elements as the workpiece is machined by the tool. In order to detect the vibration, a first sensor is arranged in the first region of the machine element and a second sensor is arranged on another machine element or in a different region of the one machine element. Actual values detected by the first and second sensors and corresponding target values are supplied to a dual controller which determines on the basis of these values, a resulting manipulated variable for the active vibration damper and actuates the active vibration damper accordingly.

Abstract: A machine tool includes a machine element, an active vibration damper arranged on a region of the machine tool for damping a vibration of the machine element, and a vibration sensor facility arranged to detect the vibration of the machine element at a first point and at a second point of the machine tool, with the vibration of the machine element to be detected being smaller at the second point than at the first point. The active vibration damper is designed to damp the vibration of the machine element as a function of a variation between a first actual value detected by the vibration sensor facility at the first point and a second actual value detected by the vibration sensor facility at the second point.

Abstract: A control device of a machine tool receives a target machining, in accordance with which a workpiece should be machined by a tool of the machine tool. The control device also receives via a human-machine interface or via an interface to an external memory device a selection, a parameterization and/or a specification of a sequence of predefined rules, which define the manner in which the machining of the workpiece should be modified in the event of undesired vibrations during machining. When undesired vibrations do not occur, as determined from acquired sensor signals, machining is carried out in accordance with the target machining. When undesired vibrations occur, the machining is modified in accordance with the rules, wherein the control device selects the rules in accordance with the selection, parameterizes the rules in accordance with the parameterization and/or carries out the rules in accordance with the specified sequence.

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: A machine tool includes a first machine element movable in a travel direction and having first and second side faces. The first and second side faces of the first machine element run parallel to the travel direction and are oriented at a right angle to each other. The first machine element is moved in the travel direction in a guideway of a second machine element by a drive unit in a positionally controlled manner. The machine tool further includes first and second vibration dampers which are oriented at a right angle to the travel direction and configured to dampen vibrations of the first machine element in respective vibration directions. At least one of the first and second vibration dampers is oriented to solely dampen a vibration in a vibration direction that is neither parallel to the first side face nor parallel to the second side face.

Abstract: An active vibration damper includes a lower outer wall for placement on a floor, and front and rear outer walls, with the front and/or rear outer wall including first and second receptacles in an outer side thereof. The first receptacle receives a permanent magnet and is pot-shaped to maintain a closed configuration of the front and/or rear outer wall. A primary part of an electrical linear actuator is fixed at least on an inside of the lower outer wall, and a secondary part is arranged above the primary part and acted upon by the primary part. Retaining elements fixed to an inside of the upper outer wall movably hold the secondary part for displacement in a substantially linear manner in a left-right direction when the primary part is correspondingly impinged on. A magnetic back iron yoke is received in the second receptacle at the height of the secondary part.

Abstract: A numerical control system determines iteratively a group of position setpoint values for axes of a production machine based on presets. When no risk of a collision of one moved element with another element exists, the group of position setpoint values is stored in a buffer store. Another already stored group of position setpoint values is read from the buffer store which then controls the axes and moves the element along a path defined by the sequence of the groups of position setpoint values. This process continues for as long as no risk of a collision exists. If a risk of a collision exists, the numerical control system brings the axes to a standstill. Previously unknown real time events are considered only in the determination of the groups of position setpoint values not yet stored in the buffer store. The groups of already stored position setpoint values are not altered.

Abstract: A machine tool has a tool and a workpiece clamped into a workpiece holder on a workpiece table and a tool. The workpiece table is rotatable about a rotation axis in a position-controlled manner by a plurality of complete revolutions, and the tool is movable at least parallel to the rotation axis in a position-controlled manner. While the workpiece table is rotated, the tool is placed at least temporarily against the workpiece on a side substantially facing away from the workpiece table, machines the workpiece, and the tool is at a distance being at least equal to a predefined minimum distance from the rotation axis. The first workpiece holder is displaced in a direction that has a component towards or away from the rotation axis on the workpiece table in a position-controlled manner during the machining of the first workpiece by the first tool.

Abstract: Movable elements of a machine are moved by a control device of the machine by controlling drives of the machine. To monitor the movement of the movable elements for collision with each other or with a stationary element, two monitoring devices check, independently from each other, using a computer program, whether there is a risk of collision in the working space. Depending on whether the monitoring devices detect a risk of collision or not, they intervene, independently from each other, in a corrective manner, in the control of the drives or not, and/or independently emit an alarm message or not. The two computer programs are designed in a diverse manner. The two monitoring devices differ from one another. One monitoring device is identical to the control device, while the other monitoring device is embodied as an industrial PC with a data link to the control device.

Abstract: Milling errors are to be prevented by repairing in particular NC parts programs by evaluating spatial information for smoothing a cutting or milling path section instead of evaluating only information along an individual cutting or milling path section. Relationships between adjacent cutting or milling path sections are thus taken into consideration in a smoothing process.

Abstract: A numerical controller of a processing machine determines corresponding setpoint axis values based on setpoint position values for position-regulated axes operating on machine elements. Before controlling the position-regulated axes, volumes to be occupied by protection bodies associated with the machine elements, a workpiece and a tool are defined and it is checked whether the protection bodies remain disjoint while controlling the position-regulated axes. Depending on the result of the checks, the controller either controls the position-regulated axes in accordance with the setpoint position values or merely executes an error response without control. The controller contains a position error field which specifies for any given setpoint axis value an actual position the tool relative to the workpiece.
