Abstract: The invention provides a solution according to which the diameters of a large plurality of cylindrical measuring pins (1A-1E) can be measured fast and accurately, while using an affordable, non-complex and universally applicable measuring apparatus. In concise summary, the key features of the invention are formed by using a two-dimensional tracing apparatus (10) having a simultaneous holding structure (12) for simultaneously holding the measuring pins in fixed positions relative to the apparatus frame (11), while the measuring pins are alongside one another with their central axes parallel to one another, and by performing first and second joint tracing operations by tracing against and along diametrically opposite first and second parts of first and second circular sections of the cylindrical outer surfaces of the measuring pins, to thereby determine measured values of the diameters.

Abstract: In a method for measuring a gauge (20), the invention provides a standard (30). The standard has a calibrated standard distance (33) between a standard reference plane (31) and a standard detection line (35), being mutually parallel. When the standard is placed with its standard reference plane onto a gauge reference plane (21), the standard is traced with a tracing point (12) of a measuring apparatus (10). Thereby it is possible to reliably measure the distance (43) between the standard detection line (35) and the apparatus reference plane (11), and hence the distance between the gauge reference plane (21) and the apparatus reference plane (11). The invention allows to reliably measure gauges in an affordable, non-complex measuring apparatus, in cases where, in order to reliably measure gauges in the apparatus, such gauges cannot be placed with their gauge reference planes onto the apparatus reference plane.

Abstract: The invention provides a solution according to which many various circumferential toothing contours (93) of many various toothed revolving objects (90) can be measured accurately and quickly by means of an inexpensive apparatus (1). In concise summary, the key features of the invention are formed by detective tracing actions of two asymmetrically sharp tracer fingers (11, 12), wherein said detective tracing actions take place at opposite tooth flanks (91, 92) during opposite rotation directions (41, 42) between the tracer fingers and the circumferential toothing.

Abstract: A method for determining a geometric parameter of an axial cross section of internal or external screw thread, comprising, with at least one probe, mechanically probing in radial direction two screw thread profiles of the screw thread to be measured, at two probing positions which are located diametrically opposite each other and which are both situated in a plane through a centerline of the screw thread, measuring a distance in said plane through the centerline of the screw thread in radial direction with respect to the screw thread between the probes in probing position, while the at least one probe is a wedge probe, the method further comprising the setting of a probing width of the at least one wedge probe, determining the geometric parameter on the basis of the measured distance between the probes in probing positions and a pitch of the screw thread.

Abstract: The invention relates to a method and apparatus for quickly and automatically centering and inserting substantially parallel cylindrical or conical measuring objects having very different nominal diameters, such as a smooth axis, outside screw thread, smooth bores, and inside screw thread, in a one-axis measuring system such as, for instance, a universal one-axis measuring machine, with a view to enabling accurate measurement of diameter quantities, such as minor diameter, pitch diameter and outside diameter of screw thread, without it being necessary that, preceding the measurement, first the points of reversal have to be manually searched for, while the influence of the centering clamping force upon the magnitude of the measuring forces between the two measuring plungers and the surface of the measuring object is very small or nil.

Abstract: The invention relates to the determination of the complete two-dimensional axial cross section of internal and external screw threads and similar workpieces, wherein in a plane through the centerline of the workpiece, two screw thread profiles which are located diametrically opposite each other are measured through two two-dimensional scan measurements in this plane or through arithmetic construction based on two profile depth measurements with a measuring ball or measuring wire, further on the basis of the assumption that the screw thread profiles in question further have a known dimension and geometry, whereafter these two opposite profiles are linked to each other by performing one or more linked measurements such as, for instance, the outside diameter in the case of external screw thread and the core diameter in the case of internal screw thread.

Abstract: Method and device for accurately measuring a longitudinal contour of a measuring object, wherein use is made of clamping members for retaining a measuring object to be measured; a scanning arm which is pivotable about an axis transverse to a longitudinal center line of the clamped measuring object and whose free end comprises one scanning needle, the scanning arm being mounted on a driving device which, in operation, can move the scanning arm in one linear direction of movement parallel to the longitudinal center line of the measuring object, and means being provided for detecting the angular displacement of the scanning arm and the position of the scanning arm in said one linear direction of movement; and a processor for processing information regarding the angular displacement and the position of the scanning arm, wherein a contour measurement is made in such a manner that the scanning needle moves along a contour flank in downward direction only, i.e. in the direction of the bottom of a profile groove.
