How is surface profile calculated

A leader arrow connects the feature control frame (further referred to as FCF) of the profile of a surface tolerance to the part feature. Like any other FCFs in GD&T, the profile of a surface FCF can be divided into three distinct blocks. These are: 1. Geometrical tolerance block 2. Feature tolerance block 3. … Meer weergeven The profile of a surface is an extremely powerful and versatile GD&T callout.
