Concept glossary

Threading Part Program
A program created to machine threads on a CNC Lathe using G92 or G76 threading cycles.
Minor Diameter
The smallest diameter of a thread, calculated as Major Diameter minus 2 times Single Side Depth.
Major Diameter
The largest diameter of a screw thread.
Single Side Depth of Thread
The depth of one side of a thread, calculated as .6495 divided by the number of threads per inch for American Standard Threads.
Tool Offsets
Values set for tool position relative to part zero during CNC setup.
Part Zero
The reference point on a workpiece from which all measurements are taken during machining.
External Thread
A thread cut on the outside of a cylindrical workpiece.
