Introduce as the solution to the "pivot point problem." Without it, programs are locked to a specific tool length and machine geometry; with it, the controller manages the tool tip path in real-time, enabling greater flexibility and accuracy. 2. Technical Fundamentals
The standard FANUC syntax for G43.4 is as follows: fanuc g43.4
-axis retraction to a safe clearance plane before initiating or canceling G43.4. Introduce as the solution to the "pivot point problem
Activating a rotary axis while G43.4 is active but the tool tip is not at the correct pivot distance. Fix: Always be at a known, safe Z position before commanding A , B , or C . safe Z position before commanding A
