摘要:
A coordinate measuring machine has a coordinate measuring machine body and a controller. The coordinate measuring machine body has a probe having a measurement piece and a drive mechanism for driving the probe. The probe has a drive unit for driving the measurement piece. The controller includes a first measuring unit and a second measuring unit. The first measuring unit measures a displacement of the measurement piece driven by the drive unit. The second measuring unit measures a displacement of the probe. The measurement accuracy of the second measuring unit is lower than the measurement accuracy of the first measuring unit.

There are provided a measuring method and a measuring system which enable creation of a measurement route with ease to thereby enable three-dimensional measurement to be quickly performed even if an object to be measured has a complicated shape or configuration. An object to be measured is shot. A plurality of images obtained by the shooting are combined together to generate a combined image of the object. A measuring region of the generated combined image is designated. A measurement path measuring program is created by inputting parameters for creating a measurement path. The designated measuring region is measured along the measurement path according to the created measurement path measuring program.

Provided are a measuring section (210) including a vibrating contact-type probe having a measuring force detection circuit (219) which detects a measuring force acting to the contact portion (212); a moving unit (a three-dimensional drive mechanism (300), a vertical movement drive mechanism (220)) that moves the measuring section (210) relative to a workpiece surface (S); and a drive control unit (400) that controls the moving unit based on the magnitude of the measuring force output from the measuring force detection circuit (219). The drive control unit (400) includes: a scanning-measurement control section (410) that moves for scanning the contact portion along the workpiece surface (S) with the measuring force maintained at the designated scanning measuring force; and a touching-measurement control section (420) that conducts touching-measurements on the workpiece surface (S) in a repeated manner, in the measurements the contact portion (212) being adapted to intermittently contact the workpiece surface (S) at a touch detecting measuring force.
摘要:
An image measuring method comprises making no stop of an imaging means relative to a measurement stage at measurement positions (MP1-MP3), and capturing instantaneous images to acquire information required for measurement. A first direction to a measurement position (MP1) to be measured next and a second direction from the measurement position (MP1) to a next measurement position (MP2) form an angle therebetween. If this angle exceeds a certain angle, an overshoot path is formed at a location beyond the measurement position (MP1) in the first direction. The larger the angle formed between the first direction and the second direction, the lower the measurement speed at the measurement position (MP1) is made.

A mobile communications terminal having a communicator for transmitting and receiving a signal to/from a base station is connected to a measuring instrument through wireless medium and a cable. A control processing software stored in a memory of the mobile communications terminal is executed. The mobile communications terminal converts the measurement data acquired by measurement of the measuring instrument into the same format as the signal transmitted to and received from the base station and the converted measurement data is read into a controller to store in a storage. The measurement data is transmitted from the communicator to the base station to be stored in a data storage and published on a web site in a manner that a third party can check.

Components of a measuring tool such as a main beam (11) and a slider (12) of a caliper gauge (1) are formed by a synthetic resin containing carbon nanofiber and an electro-conductive electrode (15) is formed on the surface of the main beam (11) at a predetermined pitch, so that a production process can be simplified, rigidity of the components can be enhanced, linear expansion coefficient can be reduced, and anti-frictional properties can be improved, thus enhancing durability while improving measurement accuracy.
摘要:
A manufacturing system of the present invention comprises NC machine tools 21-2n each for processing a work in accordance with a process program having a process condition; a measuring device 3 for measuring the work processed by the NC machine tools 21-2n; and computers 5, 81-8n for modifying the process condition of the process program on the basis of a measured result from the measuring device 3. The computer 5 produces a correction data file for modifying the process condition on the basis of the measured result from the measuring device 3. The correction data file is a file that contains correction values for each of processed parts stored in variables capable of being referred directly or indirectly from the process program. The correction data file is transferred to the NC controllers 91-9n prior to the NC machine tools 21-2n processing the work. The NC controllers 91-9n modify the process condition by the process program with reference to the correction values stored in the variables of the transferred correction data file.
