CYCLE84: Siemens Rigid Threading

Siemens cycle for tapping synchronized with the spindle.

For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.

Frequently Asked Questions (FAQ)

What does CYCLE84 mean in a CNC program?

Siemens cycle for tapping synchronized with the spindle. In the catalogue it appears as "Siemens Rigid Threading", within the Siemens cycles family.

How is CYCLE84 written on each control?

Siemens: CYCLE84(...). The exact syntax depends on the control version and the machine parameters: always confirm with the manufacturer's manual.

Can you give me an example of CYCLE84?

CYCLE84(...) — Siemens cycle for tapping synchronized with the spindle.

Which other codes is CYCLE84 combined with?

In practice CYCLE84 appears alongside these codes: G84, M03/M04/M05. It is worth reading them together, because the state one leaves behind conditions what the next one does.

Which machines use CYCLE84?

CYCLE84 is used in: Milling, Mill-turn.

What should you watch out for with CYCLE84?

High risk: a mistake here can cause a crash, a broken tool or an out-of-tolerance part. Simulate the program and dry-run it before cutting.
