Information summary:

The function of CMM measuring bracket

The measuring bracket is an auxiliary bracket when measuring parts with a three-coordinate measuring instrument. Its main function is to position parts and facilitate three-coordinate measurement. All its supporting surfaces (points) and positioning datum.

Measuring the function of CMM support

CMM measuring bracket is a kind of auxiliary bracket when measuring parts with CMM. Its main function is to position parts and facilitate CMM measurement. All its supporting surfaces (points) and positioning datum planes (points) must be milled according to the CAD data of parts. Modern inspection tools are often used as measuring brackets in structural design. When the online inspection function of inspection tools and CMM measuring bracket function cannot be met at the same time, the online inspection function of inspection tools should be met first.

Qualitative and quantitative inspection of parts

In order to realize on-line inspection of parts, it is necessary to accurately install and position the parts on the inspection tool, and then check the key product characteristics (KPC) and key control characteristics (KCC) such as the part profile, peripheral tangent line, function hole position, etc. by means of visual inspection, measuring meter or caliper, so as to quickly judge the size characteristics of parts, and the deviation between parts and CAD theoretical values can also be obtained by counting measuring tools.

Key product characteristics = key product characteristics “KPC” is the special characteristics of the product, such as key and important dimensions, which make the bad review all its own characteristics.

Key control characteristics = key control characteristics “KCC” refers to process control characteristics, such as process parameters of equipment or key and important processes.
