FIFTY LINETurn G-code

Machining cycle

Threading

External and internal threads: right/left-hand, multi-start, with lead-in and lead-out

Threading cycle form (internal) with parameters and the live 2D toolpath simulator

 

Форма цикла «Резьба» (внутренняя)

Cycle form: internal threading shown — geometry and thread mode on the left, live 2D toolpath simulator on the right.

The threading cycle supports external and internal threads, right- and left-hand direction, multi-start threads, and configurable lead-in/lead-out sections for the tool.

The threading motion syntax switches between G32 and G33 with a selectable pitch address letter (I/K/F) — matching your specific controller and post-processor.

Who needs this cycle

Needed for cutting standard cylindrical threads — from fasteners to multi-start threads — without manually calculating passes.

Key form parameters

  • External/internal thread diameter
  • Thread pitch
  • Number of starts
  • Length of the threaded section
  • Lead-in and lead-out
