Continuous development in aerospace industry puts increasingly higher challenges for manufacturers of aerospace parts. The production process of aerospace parts must meet strict requirements. One of them is inspection of part’s dimensions at the various stages of its production. It is important to proceed with the measurements when the part reaches desired temperature (usually 20°C). Temperature of the parts after machining process may be raised to approx. 60°C, hence they need to be cooled down. Cooling requires especially long time in case of large volume parts, which leads to prolongation of their delivery time. The research and development work in this field is therefore focused mainly on developing new solutions which may accelerate the cooling process. The present study describes the influence of temperature of workpiece on the result of dimensions measurement and a new design of refrigerator developed and patented by WALDREX Sp. z o.o. Refrigerator is equipped with an insulated container with cooling coil. The container is fixed in a stainless-steel frame. Provided solution enables fast and cost-effective cooling and keeping workpieces at a given temperature.
