WebApr 1, 2024 · The broaching load of GM (S2) can be reduced by 63.6 N, and the load reduction ratio is 8.11 %. The measured data show that the microstructure surface of broach can reduce the broaching load. The reduction of broaching load can be attributed to the diminution of tool-chip contact area by microstructure surface.
