ThreadRef - Thread data and reference plugin for GibbsCAM
ThreadRef Overview
ThreadRef is a thread data calculator and reference plugin for GibbsCAM.
It provides complete thread geometry data, tolerances and 3-wire measurement data for 13 thread standards.

Thread Data Table
Thread data tables for 193 standard thread sizes with instant pitch lookup, thousands of tolerance combinations, plus freeform entry for any custom thread size.
190+ standard sizes (Metric, UN)
39 pipe sizes (24 NPT + 15 BSP)
3,900+ tolerance variations on standard sizes alone
Unlimited freeform combinations for 8 thread families
Pipe threadTaper Data (NPT/BSP)
Hand-tight engagement length (L1)
Effective thread length (L2)
Pitch diameter at gauge plane (E1)
OD at small end / OD at large end
ID at small end / ID at large end
3-Wire Measurement
Useage of precision wires of known diameter (W) and a micrometer to measure the dimension across the wires (M)
Calculates Best wire size for all parallel and symmetrical threads
Calculates acceptable wire range (min/max)
Calculates measurement over wires (M) at max and min pitch diameter
