Preface
1 i5 L0 x( ~; \( l8 ITechnical developments, leading to higher performance, higher efficiency, lower pollutions
and greater reliability, and the constraints imposed by economy and the need for
rationalization, greater cooperation with licensees and subcontractors, make it necessary
to have completely toleranced drawings suitable for the function, for manufacturing
. F8 a* `9 D1 D' Dand inspection.
“Completely toleranced” means that the geometries (form, size, orientation and location)
of geometrical elements of the workpiece are completely defined and toleranced.
Nothing shall be left to the individual judgement of the manufacturer or inspector. Only
with this approach can proper functioning be verified and the possibilities available for
economization and rationalization in manufacturing and inspection be fully utilized.
This book presents the state of the art regarding geometrical dimensioning and tolerancing.
It describes the international standardization in this field, which is laid down
$ U" D. o3 w+ @1 X: m( `in ISO Standards. It indicates the deviations between the American Standard ASME
Y14.5M, the former East European Standards and the ISO Standards. It describes the
additional specifications laid down in the German Standards (DIN Standards). Possible

What has to be regarded for manufacturing within the geometrical dimensioning and
tolerances is explained.
Principles for the inspection of geometrical deviations are given, together with a

and inspection.
