Is there a specification for the calibration of the three dimensional measuring instrument?

The current effective calibration specification for three-dimensional measuring instruments is the JJF1064-2010 Calibration Specification for Coordinate Measuring Machines.

Extension of knowledge points:

Three-dimensional measuring instrument mainly refers to an instrument that measures by taking points in three dimensions. The main principles are:

The measured object is placed in the three-dimensional measurement space, the coordinate position of each measurement point on the measured object can be obtained, and the geometric size, shape and position of the measured object are calculated according to the spatial coordinate values of these points. The basic principle is to obtain the discrete spatial point position of the measured geometric element through the cooperation of the detection sensor (probe) and the measurement of the spatial axis movement, and then complete the analysis and fitting of the measured point (point group) through certain mathematical calculations, and finally restore the measured geometric element, and calculate the deviation between it and the theoretical value (nominal value) on this basis, so as to complete the inspection of the measured part.

Three-dimensional measuring instrument, mainly refers to a three-dimensional point measurement instrument, the market is also called three coordinates, three coordinate measuring machine, three-dimensional coordinate measuring instrument, three-dimensional. I am doing metrological verification, the current effective metrological calibration specification is JJF1064-2010 coordinate measuring machine calibration specification, I hope to give praise!

Yes, the latest in China is JJF1064-2010, and the international use of ISO-10360 specification.

Hello dear! <>

Three-dimensional measuring instrument electrical inspection process: 1Plug in and turn the instrument switch on.

2.Turn on the counter power switch. 3.

Turn on your computer to test. The measurement readings of the three-dimensional measuring machine are transmitted to the computer by the computer connection software program for further analysis and recording 4Observe whether the coordinates displayed by the computer and the counter are consistent.

Observe stability: move the probe up and down the object to be measured, and record the change of its data. Observe repetition:

Measure for 2 minutes to test the repeatability of the system. When measuring the diameter of a rigid probe or an electronic probe, calibrate it with a standard ball. 5.

Take any point on the surface of the workpiece, hand pull the rigid probe, let the probe touch the surface of the workpiece, when the probe touches the surface of the workpiece, use the foot switch, enter the coordinate value of the point. 6.Take any four points on the surface of the workpiece about equidistant points, pull the electronic probe by hand, let the probe touch the surface of the workpiece, when the probe touches the surface of the workpiece, the probe lamp will go out, and make a sound, indicating that the coordinate value of the point has been entered, and then measure the plane to be measured in the coincidence section.

After the 4 points of the measured plane are entered, the center coordinates of the outer diameter circle and the size of the circle diameter can be measured and recorded. 7.And then measure the inner diameter of the hole:

Unscrew the z-axis and pull the probe into the inside of the workpiece, positioning the probe approximately 5 mm below the upper edge of the workpiece. 8.The angle at which two lines cross the measurement surface.

9.After understanding the functions of each filial piety part of the instrument and the various functions of the computer connection software of the three-dimensional measuring machine, pull the probe back to the appropriate position and lock it. 10.

Turn off the power. 11.Iron instruments and equipment oil maintenance, marble instruments and equipment maintenance of Shilin.

Recording of Results: Attach a record of observations to the report. The measured data in each step are recorded separately and compared with the measurement results of the decimeter, vernier ruler and angle gauge.
