In recent years, more attention has been paid to additive wire printing technologies. Due to the peculiarities of printing with wire, the hardness of the workpiece is signifi cantly higher than with traditional forging. An increase in hardness leads to an increase in cutting force. The aim of the work is to study the cutting force during milling workpieces of stainless steel 0.4 C-13 Cr obtained by electron-beam surfacing. Research Methods The specimens were obtained by surfacing wire from martensitic stainless steel 0.4 C-13 Cr. The microstructure of the specimens was studied in this work. The main attention was paid to the study of cutting forces during the processing of specimens. The work investigate specimens obtained by electron-beam surfacing with 0.4 C-13 Cr steel wire. The cutting forces arising during milling of these specimens are determined. To carry out the research work, a standard methodology for conducting experiments to determine cutting forces was chosen. However, to determine the forces Pz and Py, a fourfl ute (z = 4) milling cutter was used and the milling width was less than 2 mm. Results and discussion. The structure of the specimens obtained by electron-beam surfacing is tempered martensite. It is established that high-speed milling, high-effi ciency milling and conventional milling are suitable for processing such workpieces. For processing thin-walled workpieces made of martensitic stainless steel after its manufacture by the method of electron-beam surfacing, it is necessary to use only carbide cutters with a diameter of at least 12 mm. The cutting modes obtained in the study make it possible to reduce the temperature of the cutting edge, cutting force and bending of a low-rigid end mill. So, in the course of the study, it was possible to select modes that reduce the vibration of the machine-device-tool-part system.
