Examples of the ideal vs the reality, and some insight into where in the manufacturing process things deviate from the ideal (sharpness of tool, vibration and chatter, etc.)
- [Instructor] Before we talk about…geometric dimensioning and tolerancing,…let's take a look at some limitations…of standard dimensioning using plus/minus tolerancing.…Most engineers will be familiar…with standard dimensioning practices.…Standard dimensioning tools…are intrinsic features of typical CAD programs.…A feature or geometry is drawn…and then a dimension is assigned to it…to define the geometry or location of that feature.…There are many style guides online…which describe best practices…for adding dimensions to your 2D drawing or 3D part.…While those guides might make the dimensions more readable,…they fall short of fully and completely…defining the geometry.…
Standard dimensions don't include a way…to define fixed reference features…that can be used as a consistent starting point…for taking measurements.…Dimensions can also be placed…without taking into consideration…the ease or difficulty of measuring the actual dimension.…Often, standard dimensions can be interpreted…in multiple ways…and not necessarily the way the designer intended.…
