If you want to ensure your machine matches its factory settings during this process, I can help you if you provide a few more details. Please let me know:
If you’ve adjusted Parameter 1860 but rigid tapping is still problematic, check these:
FANUC parameter 1860 has a wide range of applications in CNC machining, including:
Without this correction, your rigid tapping cycles would produce out-of-tolerance threads, and your spindle would never stop at the exact same position twice. fanuc parameter 1860 work
Over the next days, 1860 kept surfacing in different machines, always with the same impossible decimal, always with a faint afterglow on the logs like a footprint. We replaced boards, reflashed firmware, and ran diagnostics that returned perfect green bars and polite assurances. Yet every night a single robot would hesitate, then move on as if apologizing.
The correct setting of FANUC parameter 1860 is crucial for achieving accurate and precise machining results. Here are some reasons why:
Power off the CNC machine completely once more, then power it back on. 4. Establish the New Reference Position If you want to ensure your machine matches
To edit it, you must be in MDI mode and have Parameter Write Enable (PWE) set to 1.
Works alongside 1860 to log secondary reference data or expanded coordinate offsets.
The primary function of parameter 1860 is to enable and set the scaling ratio for a specific axis. By adjusting this parameter, users can: We replaced boards, reflashed firmware, and ran diagnostics
Every absolute linear scale or rotary pulse coder tracks position across its full length or rotational cycle. However, when the mechanical component of an axis (such as a ball screw or a casting block) is mated to the servo motor, the feedback device's absolute zero point rarely aligns perfectly with the desired physical machine zero.
If your machine's zero point is slightly off (e.g., after a minor crash), you might adjust (Grid Shift).
