Mechanical Engineering Tolerances Resources

GD&T Composite Position Tolerance Calculator for Dimensional Inspection:

External Feature of Size - post, tab, pipe, etc...

Assumptions:

• Applies to an External Features of Size (Tab, Boss Projection etc..)
• PLTZF tolerance applied at MMC
• FRTZF tolerance applied at MMC
• All dimensional unit applied with uniform units - all inches, mm, m, etc.
• Datum applied at RFS
• Datums are normally othogonal to FOS for PLTZF
• Complex, non othogonal datums not supported 
• FRTZF datum is perpendicular to features
• X and Y measurements taken with datum's established
• Up to fifteen (15) features can be calculated
• Hole feature #1 is used as the origin for the FRTZF position tolerance calculations
