This part of ISO\u00a014405 establishes the default specification operator for angular size and defines a number of special specification operators for features of angular size: cone (truncated, i.e. frustum, or not), wedge (truncated or not), two opposite straight lines (intersection of a wedge\/truncated wedge and a plane perpendicular to the intersection straight line of the two planes of the wedge\/truncated wedge, intersection of a cone\/frustum and a plane containing the axis of revolution of the cone\/frustum). See Figure\u00a01 and Figure\u00a02.<\/p>\n
This part of ISO\u00a014405 also defines the specification modifiers and the drawing indications for these angular sizes.<\/p>\n
This part of ISO\u00a014405 covers the following angular sizes:<\/p>\n
\u2014\u00a0\u00a0\u00a0 local angular size:<\/p>\n
\u2014\u00a0\u00a0\u00a0 angular size between two lines;<\/p>\n
\u2014\u00a0\u00a0\u00a0 portion angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 global angular size:<\/p>\n
\u2014\u00a0\u00a0\u00a0 direct global angular size:<\/p>\n
\u2014\u00a0\u00a0\u00a0 least squares angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 minimax angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 rank order angular size\/indirect global angular size:<\/p>\n
\u2014\u00a0\u00a0\u00a0 maximum angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 minimum angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 average angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 range of angular sizes;<\/p>\n
\u2014\u00a0\u00a0\u00a0 mid-range angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 median angular size;<\/p>\n
\u2014\u00a0\u00a0\u00a0 standard deviation of angular size.<\/p>\n
This part of ISO\u00a014405 defines the meaning of tolerances of angular sizes indicated as<\/p>\n
\u2014\u00a0\u00a0\u00a0 + and\/or – limit deviations, e.g. 0\u00b0\/-0,5\u00b0, or<\/p>\n
\u2014\u00a0\u00a0\u00a0 indicated with upper limit of size (ULS) and\/or lower limit of size (LLS), e.g. 35\u00b0 max. or 15\u00b0 min., 34\u00b0\/36\u00b0,<\/p>\n
\u2014\u00a0\u00a0\u00a0 with or without modifiers.<\/p>\n
This part of ISO\u00a014405 provides a set of tools to express several types of angular size characteristics. It does not give any information on the relationship between a function or a use and an angular size characteristic.<\/p>\n","protected":false},"excerpt":{"rendered":"
