process description of profile grinding
Metrology for Manufacturing: surface measurement
On-process measurement; Direct Measurement Methods Direct methods assess surface finish by means of stylus type devices. Measurements are obtained using a stylus drawn along the surface to be measured: the stylus motion perpendicular to the surface is registered. This registered profile is then used to calculate the roughness parameters.
