: Using these exact dimensions reduces the variety of tools needed in a workshop, as specified in the DIN 509:2006-12 technical documentation . Visualizing the Undercut
This designation is – replaced by DIN EN ISO 4046 and ISO 2081 (for zinc coatings).
Modern Computer Numerical Control (CNC) machines, particularly those running advanced systems like the HEIDENHAIN TNC 640 or MANUALplus, have specific "cycles" or canned cycles for "Undercutting." The programmer simply inputs the code referencing DIN 509 E . The machine then automatically calculates the toolpath for the 0.6mm radius and 0.2mm depth based on the specific diameter of the shaft being machined. For example, the G25 cycle on some controls is specifically designed to generate DIN 509 E undercuts. This automation reduces the number of specialized tools required, lowering production costs.
: The term "EXCLUSIVE" might imply a high level of quality, a specific application, or perhaps a proprietary specification used within certain industries.
"DIN 509" is a multi-faceted standard. The table below clarifies common areas of application.
When a blueprint restricts a manufacturing step to an callout, it acts as a rigid boundary constraint for both CAD designers and CNC machinists. This exclusivity serves three vital roles: Perfect Flush Assemblies
The designation refers to a specific type of relief groove (also called an undercut) used in mechanical engineering for turned parts and bores. These grooves provide clearance for subsequent machining tools (like grinding wheels) and ensure mating parts can sit flush against a shoulder. Specification Details
