Mechanical Engineering Tolerances Resources

GD&T Composite Position Tolerance Calculator for Dimensional Inspection:

Internal Feature of Size - hole, slot, cutout, etc..

Assumptions:

• Applies to an Internal Feature of Size (Hole, slot, 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
• Feature #1 is used as the origin for the FRTZF position tolerance calculations
