A cross-sectional profile measuring method of measuring cross-sectional profiles of an object at plural measurement sections of the object with a contact probe, includes: circularly moving the probe along a route around a circumference of the object at one of the measurement sections, a distance of the moving being longer than a measurement range corresponding to the circumference of the object by a predetermined overlapping range consisting of an acceleration range and a deceleration range; and moving the probe to next one of the measurement sections through a transfer range in a movement direction oblique to a continuous direction in which the cross-sectional profiles are adjacent to one another to offset a distance corresponding to the overlapping range.

Cross-sectional profile measuring method

A method of controlling a numerical control machine tool, includes generating a flag which designates a kind of operation of the numerical control machine tool and an operating variable which is used for controlling the operation of the numerical control machine tool, based on an instruction used for controlling a three-dimensional measuring device different from the numerical control machine tool, storing the flag in a flag storage area and storing the operating variable in an operating variable storage area, selecting an operation to be executed by the numerical control machine tool by referring to a value of the flag stored in the flag storage area, and executing a control of the selected operation of the numerical control machine tool in accordance with a value of the operating variable stored in the operating variable storage area.

Geometrical errors in a coordinate measuring machine are measured while works with various weights are mounted on the coordinate measuring machine. Compensation parameters are derived from measured results per a weight of a work and stored. A compensation parameter corresponding to a weight of a work to be measured is appropriately read out to correct measured coordinates of the work to be measured.

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.

A distribution of sample points, which are obtained by a two or three-dimensional coordinate measuring machine, is examined to classify into zero through third degrees. A geometry element is discriminated on the basis of the distribution of the sample points (zero through third degrees) and the number of the sample points. When the number of the sample points is equal to 2 or more and the distribution of the sample points is of the second degree, the geometry element can be discriminated as a plane or a circle in consideration of the probe moving direction. When the number of the sample points is equal to 6 or more, the geometry element can be discriminated as a cylinder or a circular cone on the basis of calculation of a half vertical angle of a circular cone that is specified from the sample points.

Method and apparatus for measuring geometry elements

An apparatus for calculating an operating time of a measuring machine, includes: a part program storing unit storing a part program; a command analyzing unit extracting commands relating to movement of a measurement probe from the part program stored in the part program storing unit, calculating operating times required for the measuring machine to implement the respective extracted commands, on the basis of movement parameters for the movement of said measurement probe, and summing up the calculated operating times to calculate a total operating time from a start of measurement to an end of measurement; and a displaying unit displaying the total operating time thus calculated by the command analyzing unit.

System for calculating an operating time of a measuring machine

A part program (measurement procedure) file 61 including definition information that defines the shape of a measurement object and measurement procedure information that defines a measurement procedure is read by a part program editing/executing section 62. The part program file 61 is used to control and edit a measuring apparatus. A solid modeler 65 generates solid models of the measurement object and a probe in a virtual space with the definition information and the measurement procedure information included in the part program file 61. The solid models are displayed on a displaying section 66. A measurement result can be displayed in the virtual space. With the measured result, a solid model can be generated. With the generated solid model, a part program file 61 is generated.
