Abstract The article presents the test results of surface quality parameters after broaching heat-resistant steels grades: 1.7335 (13CrMo4-5) and 1.4841 (X15CrNiSi25-20). aim work is to determine technological methods obtaining lowest treated roughness, layer hardening elimination defects broaching. To investigate influence cutting conditions (cutting speed, tool geometry feed) on roughness har...

The aim of this study, is to use finite element simulation to achieve the optimal geometry of a broaching tool that creates the lowest tensile stress at the machined surface of the Ti6Al4V alloy. It plays a major role in reducing production costs and improves the surface integrity of the machined parts. The type and amount of residual stress determined by the thermal and mechanical loads transm...

The efficiency of the application a new technology for fir-tree slots treatment in turbine discs based on combination pre-slotting operations «house» by hydro-abrasive (HAT) and final broaching herringbone CNC machine comparison with milling, deep grinding EDM-ing methods is viewed. Problems arising within manufacturing operating broaches often cause down-time both types: main tool production. ...
