Mechanical production methods and their surface roughness.
Surface roughness from mechanical processing like
- flame cutting
- planning, shaping
- electron beam
- boring, turning
- barrel finishing
- electrolytic grinding
- roller burnishing
- sand casting
- hot rolling
- investment casting
- cold rolling, drawing
- die casting
