A go no go gauge should be used at the same temp as the part and is usually a shop floor type measurement. Thermal expansion is the enemy when holding extremely tight tolerance. CMM measuring is normally done at 70 deg F and a part needs to be exposed to that temp for 24hrs depending on size to acclimate ideally.
