DIN 3967 (1953) Now Available in TBK

When old drawings meet modern engineering – DIN 3967 now available in TBK.

Re-engineering often starts with a challenge:

  • An old drawing
  • An outdated tolerance specification
  • And the question: How do we reliably validate this today?

To support exactly these use cases, the recognized TBK software now includes the historic tolerance standard DIN 3967 (1953) integrated specifically in response to user demand.

DIN 3967 defined:

  • Gear quality classes
  • Tooth thickness tolerances

DIN 3967 (1953) is now available in TBK as an additional tolerance standard next to:

  • DIN 3961
  • DIN 58405
  • ISO 1328
  • ANSI/AGMA 2015

Within the calculation modules for:

  • Single cylindrical gears
  • Cylindrical gear pairs
  • Planetary gear trains
  • 3- and 4-gear train systems
  • Racks and pinions

This allows direct evaluation of old drawing specifications.

Modern software must not only support the latest standards, it must also understand engineering history.

With DIN 3967 (1953) integrated, TBK bridges the gap between 1953 and today.
