Relationship feed rate to surface roughness

Operating principle “Masterfinish“

Improved surfaceWith the same feed rate an insert with "Masterfinish" cutting edge attains a roughness value Ra which issignificantly higher than that of a conventional insert.

Reduced machining timesIf you want to reach the same Ra-value as with a standard insert, a twice as high feed rate can be appliedfor the insert with "Masterfinish" cutting edge ( = shorter production times per component!).

ISO-DIN measured surface roughness

Average roughness value Ra (DIN 4768)This is defined as the arithmetical mean of theabsolute sums of the roughness profile R withinthe entire measured length lm.

Average roughness depth Rz (DIN 4768)This is defined as the average value resultingfrom the single roughness depths of fivesuccessive single measured lengths le.

Single surface roughness depth Z1 ... Z5This is the vertical distance between the highestand the lowest point of the roughness profile Rwithin a single measured length le.

Maximum surface roughness depth Rt(DIN 4768/1)This is the distance between the elevation anddepression of the line within the measured length(reference distance) of profile filtered accordingto DIN 4768 sheet 1.
