A measurement apparatus includes a sensor that measures a workpiece, a multi-axis robot that moves the sensor in a three-dimensional space, a position determination part that determines i) a plurality of measurement positions that are positions along a normal direction at each of a plurality of positions to be measured on the workpiece and ii) a direction of the sensor at each of the plurality of measurement positions on the basis of at least either design data or captured image data indicating the geometry of the workpiece, a moving control part that sequentially moves the sensor to the plurality of measurement positions by controlling the robot, and a measurement control part that outputs measured data indicating a result that the sensor measured at each of the plurality of measurement positions in association with the plurality of positions to be measured.

Measurement apparatus, control apparatus, and control method

A stylus abrasion detection method includes obtaining a measurement curve of a standard specimen in which an unevenness that changes periodically is formed on a surface, by causing a stylus to trace along the surface of the standard specimen, detecting a displacement of the stylus in a direction perpendicular to the tracing direction, and using the displacement for obtaining the measurement curve; performing a frequency analysis on the measurement curve; calculating an abrasion amount of the stylus from a result of the frequency analysis; and displaying the abrasion amount calculated by the abrasion amount calculation.

Stylus abrasion detection method and surface property measurement device

A surface texture measuring instrument includes: a measuring device that includes a detector for detecting surface texture of a workpiece and an X-axis movement mechanism for moving the detector in a measurement direction; an elevation inclination adjuster capable of adjusting an elevation position and an inclination angle of a table on which the measuring device is mounted; a stage on which the workpiece is mounted; and a controller that controls the measuring device and the elevation inclination adjuster. The controller includes: a measurement controller that controls the X-axis movement mechanism to conduct a preliminary measurement and main measurement of the workpiece; a computing unit that acquires a result of the preliminary measurement from the detector and obtains an inclination angle of the workpiece at which the workpiece is inclined to the measurement direction; and a positioning controller for adjusting the inclination angle of the table based on the obtained inclination angle.

Surface texture measuring instrument and measuring method

In advance to measuring texture of the workpiece by a surface texture measuring machine ( ), a workpiece orientation adjustment stage ( ) is manually moved by the surface texture measuring machine ( ) in accordance with calculated orientation correction amount of the workpiece, thus adjusting orientation of the workpiece. Since it is only necessary for an operator to operate respective adjustment means until reaching a displayed correction amount, operation thereof can be facilitated and orientation thereof can be highly accurately adjusted without impairing operability.

Surface texture measuring machine, leveling device for surface texture measuring machine and orientation-adjusting method of workpiece of surface texture measuring machine

A surface texture measuring apparatus allowing effects of vibration disturbance to be removed and a highly accurate measurement to be achieved. The surface texture measuring apparatus is further provided with a small surface texture measuring apparatus, which detects the amount of vibration of a workpiece while maintaining a detecting device in contact with the surface of the workpiece without moving the device along the workpiece. The main surface texture measuring apparatus conducts measurement with a high accuracy based on the detected unevenness value of the surface of the workpiece and on the amount of vibration detected by the small surface texture measuring apparatus.

Surface texture measuring apparatus

A surface texture measuring apparatus that ensures detection of surface texture of a workpiece even when the surface has a steep unevenness. A detecting device having a stylus is moved in the X axis direction along the surface of the workpiece, and displacement in the Z axis direction is converted into electric signals to detect unevenness of the surface of the workpiece. When the surface has a steep unevenness and the amount of displacement in the Z axis direction reaches or exceeds a threshold, a Z axis detected value and an X axis detected value obtained at that moment are output. The moving speed of the detecting device is decreased when the surface has a steep unevenness, while the moving speed is increased when the surface does not have a steep unevenness, making it possible to improve following characteristics and to reduce measurement time.
