What this standard covers
This standard specifies a filtering method. This standard applies to the formation of composite machining surface, such surface roughing and finishing left the valley formed by the synthesis of a smooth surface. For these surfaces GB/T 18777-2002 (ISO 11562) required baseline filter the results would be adversely affected ravine. Described in this standard filtering suppresses the influence valley, resulting in a more suitable baseline.
