The forming roughness details process is examined in this article. During volumetric processing (solid machining) the detail's surfaces are generated confined space. The working substance geometric characteristics influence on difficult of access zone machinability is researched. The experimental researches of evenness of figurine details centrifugal planetary treatment are lead.
