FANUC option functions, backup files, certification messages and application conditions.
Using the 0i-F descriptions manual, point coordinates and signed triangle area explain single- and dual-axis mirroring. Geometric reflection, arc-direction handling and physical spindle rotation remain distinct to avoid reversing the program twice.
Read article →The cutter compensation C chapter of the 16i/18i-MB manual distinguishes geometric inaccessibility, compensation data and path-reversal checks. An internal-fillet example explains why reducing the offset value is not a valid way to clear an alarm.
Read article →A motion-free variable trace based on the 0i-D common operator’s manual compares G65 with M98. It explains argument A mapping to #1, restoration of local-variable levels, and why common variables are not isolated by those levels.
Read article →For a G01 linear model on a 0i-F machining center, inverse-time feed formulas calculate time and speed before and after segmentation. The article distinguishes G93 F from feed per minute and recalculates F to preserve ideal speed.
Read article →The 0i-D manual distinguishes the cylinder radius, rotary-axis angle and developed-surface arc radius in G07.1. An arc-length calculation explains dimensional errors, followed by key restrictions on mode transitions.
Read article →The original 15i/150i-MB manual distinguishes circular tangential feed from spatial-path feed. Calculations for the same hypothetical geometry show the two velocity components and why HTG semantics must be checked.
Read article →The 30i/31i/32i-B descriptions manual distinguishes life-management groups, physical tools and offset data. A remaining-life calculation separates advance warning from end of life and helps investigate dimensional changes after a replacement tool takes over.
Read article →The FANUC function catalog distinguishes built-in CNC checking from a PC/FOCAS2 implementation. The article identifies validation priorities for geometry, tool data and communications, including the impact of fixture changes.
Read article →Coordinate calculations for a four-station fixture distinguish origin translation, workpiece orientation and program selection errors. The Plus catalog defines the scope of the 48 additional coordinate systems. These are geometric checks, not a machine-ready program.
Read article →Signal paths and delay-distance calculations explain High-Speed Skip, distinguish it from Continuous High-Speed Skip, and provide a layered approach to validating measurement errors.
