Analysis of the influence of the location schemes of form-forming cutting elements on the deformation processes of step face milling cutters

open access: yesТехнічна інженерія, 2023
In recent times, methods of finishing flat surfaces with face mills equipped super-hard materials have become widespread. However, the non-stationarity of the cutting process, which is characteristic of face milling processes, leads to variable ...

Experiment study on overdepth coefficient of the cut hole in coal mine roadway excavation blasting

open access: yes工程科学学报, 2023
In rocky road drilling and blasting in coal mines, the key to work efficiency is cutting. Although blast hole depth has steadily increased with increasing rocky road excavation activities, the cut hole depth is still ordinarily shallow, which is normally

The influence of cutting forces study during finishing step face milling on the treated surfaces shaping processes

open access: yesТехнічна інженерія, 2023
The wide implementation of finishing face milling processes instead of abrasive treatment processes is explained by their high productivity and the possibility of providing processed surfaces of low roughness with the necessary microrelief.
