Din 509. DIN EN 509 DIN 509 December 1, 2006 Technical drawings - Undercuts - Types and dimensions This standard applies to undercuts on turned parts and in bores, and helps reduce the variety of tools needed to produce such undercuts DIN 509:2006-12 8 7 Machining allowances The machining allowances z 1 and z 2 specified in Table 2 offset the transition of the undercut to the machining surfaces by dimensions e 1 and e 2, respectively, which are in turn determined by the magnitude of the allowances and the relevant sidewall angles of the undercut.
