摘要： A method for correcting errors in a coordinate measuring machine having a measuring head which is adapted to move in at least two different spatial directions. Measuring scales and measuring lines are assigned to each spatial direction. The measuring lines of different spatial directions intersect, and correction values are determined along the measuring lines at predetermined values of the scales in order to correct for elastic and/or geometric errors of the scales and/or of the guiding mechanism for moving the measuring head. According to one aspect of the invention, the correction values determined along a measuring line of a first spatial direction are modified such that the modified correction value of this measuring line assumes a predetermined value at the point of intersection with a first measuring line of a second spatial direction.

摘要： A coordinate measuring apparatus for measuring a workpiece with a probe head having a probe element for contacting the workpiece. The coordinate measuring apparatus includes: a plurality of sensors with each sensor supplying a signal indicative of a coordinate measurement position and a processing unit. An interface device between the plurality of sensors and the processing unit receives the signals and supplies a plurality of output signals to the processing unit representing respective position measurement values at any given instant of time. The processing unit includes at least one smoothing function block for continuously receiving a portion of the position measurement values. The smoothing function block is adapted to determine a final position measurement value (X.sub.E, Y.sub.E, Z.sub.E or R.sub.E) of the contact point of the probe element on the workpiece in a defined standstill of the apparatus by averaging a defined number of the received position measurement values to form a mean value. The processing unit further includes a function block for triggering the averaging before the apparatus reaches standstill and continuing the averaging until standstill is determined.

摘要： The method is used to determine the elastic bending behavior of coordinate measuring machines as a result of the measuring force and the position of measuring slides in the measuring range of the machine. Correction values are determined, which are used to compensate for measuring errors caused by machine bending. The correction values are a function of the position of the measuring slides and on the measuring force between the probe of the coordinate measuring machine and workpieces within the measuring range, and are established and stored for several positions. The method can be combined very advantageously with known methods for the correction of guideway errors, which were developed on the basis of a rigid model, and with methods for the dynamic correction of machine deviations caused by vibration of machine components.
