Go-Nogo Gauge testing is a method of measuring machined parts for acceptance criteria. It is used by Ming Xiao Mfg to ensure parts meet specific industry standards. The process usually entails the use of a pneumatically operated go-no-go gauge, which is designed to quickly and accurately measure the dimensions of machined parts. The operator places the part on the gauge and then operates the pneumatic device to measure the parts and certify they meet industry standards. This method of quality control helps to ensure the parts delivered to customers are within the allowed tolerances.
