Roughness tolerance h7
Roughness tolerance h7
(OP)
Hi fellas,
I have some trouble with value over roughness symbol. The value is expressed as h7 or H7. It looks like on attached image. Anyone of You knows
which class describes it or how to translate it to Rz?

Does the drawing have a definition of H7 somewhere else like in the general notes? Sometimes when a surface texture is used over and over on a drawing they will use an abbreviated symbol in all the locations and then explain the symbol in a note.

If the long line on the right side of the triangle had another horizontal line on top than additional information could be listed (surf. roughness, grinding allowance etc.)

dgallup There is note about roughness tolerance for other dimensions (removal of the material is not permitted) and additional symbols used in the drawing: Ra1,6 and Ra3,2. Nothing else.
