Three coordinate measurement for precision parts machining
In the field of precision parts processing, three-dimensional measurement means a very high degree of precision. So, is the data of three-dimensional measurement for precision parts processing necessarily the most accurate? Is it the most worthy of our reference?
In fact, measurement is a highly specialized technology, and selecting the appropriate measuring equipment or tools also requires a certain amount of professional knowledge and experience to determine. Any measuring equipment is very accurate, and only applicable or not applicable to the measurement results can be said. Below, we will give examples to illustrate one by one:
Usually, when measuring the aperture, many people prefer to use a stopper rod for go/no go measurement, but they can also choose an inner micrometer for measurement or a three coordinate system for measurement. These three measurement tools or equipment are commonly used, and each of them has its own advantages and disadvantages. If the selection is generally based on the actual application of the part, the roundness of the inner hole cannot be recognized when using a stopper rod for go/no go measurement, However, if some parts with large gaps are installed, their functionality can be fully guaranteed and the measurement efficiency is high; For some products with higher precision requirements, an inner micrometer can be chosen for measurement. Its measurement is fast, efficient, and accurate, making it particularly suitable for measurement on the machine. When it is impossible to remove the clamp, an inner micrometer is a very good choice. For measuring inner holes with three coordinates, the measured data is very accurate, but sometimes it is not necessarily suitable for assembly.
So, in the field of measurement, any measuring equipment can only be applicable and cannot be determined by the most accurate or best.
