Know How Edge Measurement According To Bosch Standard From Mahr

Distances, geometric forms and acceptable tolerances are defined in technical drawings.

According to the drawings, all parts can be produced. An edge which is the intersection between two surfaces is created in the production line as a radius, an edge or as an edge with an undefined shape. For designers, it is easy to define radii or edges in technical drawings. It is more difficult, however, to describe edges with undefined shapes. You can find descriptions like “No sharp edge”, or “Burr not permitted”. These definitions do not allow for objective criteria for tolerances or ideal edge curves. It is also impossible to create a practice-oriented test method.

Mahr have produced a guide to Measuring edges with Maxisurf XC 20 and is available HERE to download in full
