Troubleshooting G-Code Errors in 5-Axis Milling
PART 1: FANUC 31i-B The Kinematic RealityFanuc dominates North American/Asian 5-axis shops (DMG MORI, Makino, Okuma). Its strength modular G-codes becomes a weakness when kinematics are ignored. On a head-table machine (e.g., Makino D500), the A/B axes pivot the spindle. A G-code error here doesn’t just misposition the tool it makes the entire head assembly collide with fixtures.
