Effective PMI Management with NX Hole Callouts - Part II

In our article "Effective PMI Management with NX Hole Callouts" we gave a first introduction about NX hole callouts, the associative descriptions/labels for holes and threads, which are created from multiple parameters, derived directly from the hole's feature data. Read in our blog which additioanl parameters are available and how the NX hole callouts are ballooned for inspection.

Since NX1899 there are more parameters available for the individual feature types:

Hole callouts / Feature types

A hole callout is a new characteristic type that can be ballooned within BCT Inspector, the quality management solution for NX and Teamcenter. The hole callout characteristic is similar to a text note: the remark column contains the whole callout content as text. Each hole callout / feature type (hole, drill size hole, screw clearance hole, ...) receives one main charateristics number, e.g.

42

Feature Location Label (FLL)

FLLs manage additional referenced features of a PMI (Product Manufacturing Information). In the quality process, there is a need to identify and measure each of these elements, identified by its exact position. To fulfill this specification, it is necessary to place identification labels on each of these occurrences (pattern feature count). FLLs will be applied according to number of associated objects on a PMI hole callout, e.g.

F1, F2

Hole callout parameters

Each individual hole callout parameter (FLL, diameter, dimension, angle, note) is assigned a unique sub-balloon number (sub- or integer numbers), taking into account the default tolerances, e.g.

42.1
42.2

Secondary dimension for depth

The secondary dimension for depth creates an additional Hole Callout for depth. During ballooning it will be handled as a separate hole callout. A new main characteristic number will be assigned, parameter(s) will get sub-numbers assigned. Restriction: if depth parameter is visible on the linear/radial hole callout a separate sub-number will be assigned.
