摘要： A hexapod CMM or hexapod-like CMM has a base structure and a movable structure connected to each other by at least three telescopically extendable legs via spherical joints. Each of the telescopically extendable legs comprises a linear first member and a linear second member having countersliding surfaces and are designed in such a way that allows a relative, linear movement of the first linear member and the second linear member. Further each of the telescopically extendable legs has an air cushioning mechanism, which comprises at least one air supply system connected to at least one source of compressed air and having at least one air escape. The air escape is arranged in such a way that compressed air escaping the air escape flows into a gap between the countersliding surfaces of the at least two linear members of the leg cushioning the two linear members against each other.

摘要： Embodiments of the invention include a method for compensating a force at a probe element of a probing unit. The probing unit being attached to and moved along a defined moving path with a number of moving points by a coordinate measuring machine for approaching a measuring point at an object. The probing unit comprises an actuator which is arranged and designed in such manner that a force is applicable to the probe element with respect to at least one actuating direction in variable and defined manner, the force depending on an applied actuating signal. Movement information about an expected movement of the probing unit is received, the movement information provides information about an expected displacement behaviour of the probe element relative to the probing unit due to induced forces emerging by moving the probing unit.

摘要： Object analysis comprising measuring a frequency-dependent natural oscillation behavior of the object by dynamically-mechanically exciting the object in a defined frequency range (f) by means of generating a body oscillation by applying a test signal, and detecting a body oscillation generated in the object on account of the exciting. Moreover, the method involves simulating a frequency-dependent natural oscillation behavior for the object by generating a virtual digital representation of the object, and carrying out a finite element analysis on the basis of the virtual representation comprising dynamically exciting, in a simulated manner, the virtual representation into a virtual frequency range for generating a virtual body oscillation, calculating the virtual body oscillation generated in the object on account of the exciting in a simulated manner, and deriving an object state on the basis of a comparison of the measured natural oscillation behavior and the simulated frequency-dependent natural oscillation behavior.

摘要： A machine state monitoring system for recurrently determining a change in static or dynamic properties of a geometry of a machine with positional encoders to derive a coordinate information of at least a first machine portion with respect to a second machine portion, which are movable with respect to one another. The monitoring system includes one calibration-monitoring-unit with an optical, at least two-dimensional measuring location sensing unit which is fixed to the first machine portion and configured to optically sense an at least two dimensional location information of an artifact which is provided at the second machine portion, and temporarily moved into a sensing range for determining the change in the static or dynamic properties of the geometry of the machine by a comparison of multiple of such sensings, the compensation parameters are then updated and is used to derive the coordinate information from the encoders.

摘要： A method of compensating errors in a coordinate measuring machine adapted for determination of at least one spatial coordinate of a measurement point on an object to be measured. The method comprises measuring a distance from the first reference element to the first structural component, wherein the measured distance indicates a displacement or a deformation of the first structural component, defining a dynamic model with a first set of state variables, the state variables being related to a set of physical properties of the reference module and representing an actual state of the reference module, deriving the actual state of the reference module by a calculation based on the dynamic model, and deducing compensation parameters based on the actual state.
