The development of the advanced industries of the Republic of Kazakhstan (RK, such as chemical, oil, geological exploration, etc., dictates the need to develop promising and resource-saving technologies for manufacturing parts and assemblies of the machines and technological equipment. The most problematic is to ensure control during their manufacture. This is especially seen when inspecting critical surfaces, in particular holes of the large parts. The study in this article aims to solve this problem. The analysis of the design and technological feasibility of the existing instrumentation was carried out. The results showed that their main disadvantages are low measurement accuracy, high cost and design complexity, the impossibility of controlling holes of large diameters, as well as their unstable position inside the controlled hole. Taking into account these shortcomings, a special inside gauge has been developed to control holes of the large diameters, which will allow measuring the deviation of the hole diameters from the nominal value in a wide range of sizes. The advantage of the developed inside gauge is the following: The ability to measure deviations in the diameters of large holes, the stable position of the inside gauge to control holes of large diameters, in holes during inspection, as well as ensuring measurement accuracy with a resolution corresponding to the resolution of the applied dial indicator. The patent of the RK No. 4125 has been received for the design of the inside gauge to control holes of large diameters.
