Abstract
The authors propose an algorithm for the computerized control and optimization of the cutting of threaded joints for drill pipes. They test the program by cutting screw threads on the sockets of TBPV-127 welded couplings with mechanically reinforced bits of hardened T15K6 alloy. The sockets were made of 40KHN steel with a hardness HB 285-341. Testing and analysis enabled the authors to determine the minimum thickness of the cut, to optimize shaving removal, and to increase the durability of the tools by several factors.
