leikkuupinta
Leikkuupinta, Finnish for “cutting surface,” refers to the surface produced on a workpiece as a result of a cutting or material-removal operation. It is the interface between the tool and the workpiece after a machining pass and is distinct from the original surface and from the tool contact surface.
In machining, the cutting surface is formed through chip formation, plastic deformation, and sometimes brittle fracture
Several factors influence the resulting cutting surface. Tool geometry (edge radius, rake angle, and coating), cutting
Measurement and quality control typically involve surface roughness and texture parameters (for example Ra and Rz)
