Machining impellers, turbine blades, or medical prosthetics requires continuous tool tilt to maintain proper clearance. G43.4 allows CAM to output short, simple vector moves without worrying about machine kinematics. tool tip stays at X0
Not all FANUC controls support G43.4 . You need:
As CNC machines become more intelligent, G43.4 is evolving. Modern FANUC controls (31i-B5 series) integrate TCP with:
