Ra in machining

Webb7 okt. 2024 · As machined parts will have minor visible tool marks, and the standard value of the processed surface roughness (Ra) is 3.2 μm. Finishing passes can be applied to reduce the surface roughness to 0.8, 0.4 μm or lower. This will increase the production cost of the parts due to the additional processing steps and stricter quality control.
