High surface requirements place greater demands on the tool, on the control of process parameters, and on the handling of the profiles during production. Lower productivity and the risk of increased scrapping mean that a high surface requirement will result in a more expensive product.
It is important that surface requirements and visible surface are stated on the production drawing. The markings used for this are:
| Double-dotted and dashed line | — – – — – – — – – — |
| Dashed line | — — — — — — — — |
| Dotted line | – – – – – – – – – – – – |
Surface requirement can also be specified for unmarked surface.
