Reverse Engineering in Production and the Repair Complex Profile and Large-Sized Products

Methods have been developed for monitoring and diagnosing the degree of wear and loss of the geometric shape of surfaces. A selection of technological routes was carried out for the complex restoration of working surfaces of large-sized products using electrophysical energy sources during surfacing of powders and wires. It has been shown that the cost of major repairs when restoring a screw shaft is, on average, two times lower than manufacturing a new one. It is important to monitor regularly the degree of wear of shaft turns and their local restoration using surfacing materials and technologies.
