The image measuring instrument is a precision measuring instrument. A single error in the measurement process can cause the entire measurement to fail. Therefore, in addition to the measurement specifications and requirements of the instrument, the measurement personnel must also follow the general measurement requirements of the image measuring instrument during the use of the two-dimensional measuring instrument. In industrial measurement, the image measuring instrument has a very wide range of applications. It can be used not only for workpiece measurement for quality control, but also for reverse engineering. Before starting the measurement, we first need to understand some basic requirements of the measurement in order to reduce the measurement error as much as possible and improve the measurement accuracy and stability.
The general measurement requirements of image measuring instruments:
select the appropriate workpiece fixing method; select the appropriate features on the workpiece to establish the workpiece coordinate system; select the appropriate magnification; select the appropriate lighting method; plan the appropriate measurement path and measurement method.
What are the basic requirements of the measurement process of the two-dimensional imager?
The purpose of the measurement is to obtain accurate measured values of the measured object, but there are large differences between the measured object, the measuring tool, and the measuring person in the measuring example. In order to ensure the measurement accuracy, in addition to the measurement specifications and requirements of the instrument, we must also regulate the entire measurement process so that the measurement process can be controlled. Good image measuring instrument measurement specifications should have the following requirements:
correct measurement: the measurement process should meet the agreed and well-defined requirements;
correct tools: should be proven to be suitable for the purpose and accuracy of the work Appropriate equipment and methods for measurement;
correct personnel: the measurement personnel should be competent and understand the purpose of the work;
correct process: all measurement processes should be well thought out and consistent with national or international standards;
regular review: An independent department evaluates the technical performance of all measurement facilities and processes;
the consistency of the demonstration: the measurement in one place should be consistent with the measurement in other places.
