Drawing check procedure
1.Dimensions. Is the part fully dimensioned, and are the dimensions clearly positioned? Is the drawing dimensioned to avoid unnecessary shop calculations?
2.Scale. Is the drawing to scale? Is the scale shown? What will the plot scale be?
3. Tolerances. Are the clearances and tolerances specified by the linear and angular dimensions and by local, general, or title block notes suitable for proper functioning? Are they realistic? Can they be liberalized?
4.Standards. Have standard parts, design, materials processes, or other items been used where possible?
5.Surface texture. Have surface roughness values been shown where required? Are the values shown compatible with overall design requirements?
6.Material. Have proper material and heat treatment been specified |
