CYCLE95: Siemens contour roughing

Siemens turning cycle for roughing/finishing defined contours.

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.

  • It usually replaces Fanuc G71/G70-style flows in Sinumerik environments.
  • Validates contour, allowances, machining direction and active tool.

Fanuc · Haas · Fagor

  • Fanuc: Conceptual equivalence: G71 for roughing and G70 for finishing.
  • Haas: Conceptual equivalence: Haas lathe G71/G70 cycles.
  • Fagor: Fagor uses its own turning cycles; don't copy CYCLE95 directly.

Frequently Asked Questions (FAQ)

What does CYCLE95 mean in a CNC program?

Siemens turning cycle for roughing/finishing defined contours. In the catalogue it appears as "Siemens contour roughing", within the Siemens lathe family.

How is CYCLE95 written on each control?

Siemens: CYCLE95(...). 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 CYCLE95?

CYCLE95(...) — Siemens turning cycle for roughing/finishing defined contours.

Which other codes is CYCLE95 combined with?

In practice CYCLE95 appears alongside these codes: G71, G70. It is worth reading them together, because the state one leaves behind conditions what the next one does.

Which machines use CYCLE95?

CYCLE95 is used in: Turning, Mill-turn.

What should you watch out for with CYCLE95?

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.
