työstettävyysluvulla
Työstettävyysluku is a Finnish term that translates to machinability index or machinability rating. It is a dimensionless value used to quantify how easily a material can be machined. This index is particularly relevant in the metalworking industry, where cutting, drilling, milling, and other machining operations are common. A higher työstettävyysluku generally indicates that a material is easier to machine, requiring less force, experiencing less tool wear, and allowing for higher cutting speeds and feed rates. Conversely, a lower value suggests that the material is more difficult to machine, potentially leading to increased tool wear, lower productivity, and a higher risk of surface defects.
The työstettävyysluku is not a universally standardized value and can vary depending on the specific machining
