20090139970 | METHOD AND ARRANGEMENT FOR GUIDING A MACHINE PART ALONG A DEFINED MOVEMENT PATH OVER A WORKPIECE SURFACE - A machine part is guided along a defined movement path over a workpiece surface. The machine part is held at a defined distance from the workpiece surface during this movement. For that purpose, at least one distance sensor is provided that runs ahead of the machine part with a defined lead. A plurality of distance values indicative of a distance between the distance sensor and the workpiece surface are determined along the movement path. A plurality of control values are determined as a function of the distance values. The defined distance is repeatedly adjusted by means of the control values. In accordance with a first aspect, the distance values are determined at measurement points distributed with a first grid spacing along the movement path, while the control values are determined for actuating points distributed with a second grid spacing along the movement path, the first and the second grid spacings being different. According to a second aspect, the machine part has a linear range of activity on the workpiece surface, and the distance between the machine part and the workpiece surface is controlled by means of a distance control value and an angle control value, which are derived from distance values acquired from at least two distance sensors, which are laterally offset from one another. | 06-04-2009 |
20090172962 | METHOD AND DEVICE FOR CONTACTING A SURFACE POINT ON A WORKPIECE - A probe head having a probe head base and a stylus is provided for contacting a surface point on a workpiece. The stylus is moveable relative to the probe head base and has a defined rest position relative to the probe head base. For the contacting, the probe head is moved relative to the workpiece until the stylus touches the surface point with a defined contacting force. A correction data record representing a hysteresis behavior of the stylus with respect to the rest position is provided, and the contacting force is determined using the correction data record. | 07-09-2009 |
20090184676 | METHOD AND APPARATUS FOR POSITION-ACCURATE TRIGGERING OF A MACHINE PART - A machine part, such as a laser, is moved along at least one axis of movement relative to a workpiece. Position pulses are generated by means of an incremental encoder, with the number of position pulses in a position pulse train being representative of the movement position of the machine part. A trigger signal for the machine part is generated when the current number of position pulses corresponds to a predefined number of pulses. In a preferred embodiment, the current number of position pulses and the defined number of pulses are compared remote from a higher-level drive control circuit. It is particularly preferred if the current number of position pulses and the defined number of pulses are compared in a comparator which is arranged on an interface card of a computer unit, with the drive control circuit for controlling the movement of the machine part being implemented with a closed loop controller in the form of a controller program, which is cyclically executed by a central processor of the computer unit. | 07-23-2009 |
20090271997 | METHOD AND APPARATUS FOR DETERMINING SPATIAL COORDINATES AT A MULTIPLICITY OF MEASUREMENT POINTS - In order to determine spatial coordinates of a multiplicity of measurement points along a contour of a measurement object, a probe head is provided with a probe element that is movably supported on the probe head. During movement of the probe head along the contour, position measuring values of the probe head and deflections of the probe element relative to the probe head are determined. Spatial coordinates for the measurement points along the contour are determined from the position measuring values and deflections. The probe element is kept in contact with the contour during movement of the probe head by using an actuator to produce a defined contact force. The contact force is set as a function of a differential acceleration of the probe element relative to the probe head. | 11-05-2009 |

The maximum acceleration and/or the maximum jerk is varied depending on the position of the machine part and/or depending on the alignment of the machine part. | 02-14-2013 |
20140317942 | METHOD FOR DETERMINING A CORRECTION VALUE FOR THE MONITORING OF A FLUID BEARING AND MACHINE HAVING AT LEAST ONE FLUID BEARING - A method for ascertaining a correction value for monitoring a fluid bearing of a coordinate measuring machine or other machine tool. Also disclosed is a coordinate measuring machine having at least one fluid bearing. The machine further includes a first element and a second element which are supported against each other by means of at least one fluid bearing. In addition, a control device is provided for controlling the machine. A quantity representing a pressure in the at least one fluid bearing is ascertained as a function of a position and/or orientation of the first element relative to the second element. A correction value for a pressure in the at least one fluid bearing is determined for the position and/or orientation of the first element relative to the second element. The correction value is then stored in the control device, and subsequently used for machining or measuring a workpiece. | 10-30-2014 |

20080295349 | Coordinate Measuring Machine and Method for Operating a Coordinate Measuring Machine - In a method for operating a coordinate measuring machine and to a coordinate measuring machine, a coordinate measuring device, of the coordinate measuring machine is moved in at least one direction while being driven by an electric motor. An electrical drive current which flows through the electric motor for moving the electric motor and, move the coordinate measuring device is measured. A limit value for the electrical drive current is determined on the basis of a desired speed and/or on the basis of a desired acceleration with which the electric motor or the coordinate measuring device is intended to move. If the electrical drive current reaches the limit value determined and/or if the electrical drive current exceeds the limit value determined, the coordinate measuring device is changed to a predefined state, by virtue of the computer or the microcontroller switching off one of the switches disposed in the current path. | 12-04-2008 |
20090026995 | Reliable Monitoring of the Speed in Coordinate Measuring Appliances - In a method for reliably monitoring the speed of a moveable coordinate measuring device, a first value of the speed is calculated from measured values of the coordinate measurement system. The measured values contain information on positions of the coordinate measuring device. The measured values are further used to determine the coordinates of a measurement object. A second value of the speed is ascertained from measurement signals of at least one additional movement sensor. The measurement signals can also be used for controlling a drive device of the coordinate measuring device. A fault signal can be generated if the first value and/or the second value deviate from one another, from a predetermined value and/or a limit value according to a predefined criterion. | 01-29-2009 |

20110311922 | METHOD FOR ADJUSTING AND CONTROLLING AN ACTUATING DRIVE FOR A BURNER - Before start-up of a burner, minimum and maximum actuating positions of an actuating drive are set by setting elements. During control of the actuating drive, an automatic firing mechanism receives from a position transducer position signals dependent on the actuating position of the actuating drive reached during operation. The automatic firing mechanism assigns to the minimum actuating position the position signal measured during the feedback of the minimum actuating position of the actuating drive, and assigns to the maximum actuating position of the actuating drive the position signal measured during the feedback of the maximum actuating position of the actuating drive. Using the position signals assigned to the minimum and maximum actuating positions, corresponding control parameters are determined for activating the minimum and maximum actuating positions, and the control parameters are stored. | 12-22-2011 |
