在机械制造厂的加工车间中,目前仍普遍采用直接目测和与粗糙度工作样板目测比较的方法来评定工件的粗糙度。为了了解粗糙度工作样板的使用效果,我们作了一些试验调查。
In the machining shop of the mechanical factory, the roughness of the work piece is still generally evaluated by direct visual inspection and visual comparison with the roughness working sample. In order to understand the effectiveness of the use of roughness work model, we made some experimental investigation.
