In FANUC programming, what is the Tool Center Point (TCP) and why is it important?

• A. TCP is the torque control parameter.
• B. TCP is a temperature characteristic of the tool.
• C. TCP is the calibration point on the table.
• D. TCP defines the exact position and orientation of the tool in space, used to compute end-effector pose.

Answer: (D)

The Tool Center Point is the reference point on the end-effector that defines the exact position and orientation of the tool in space, and it’s what the controller uses to compute the end-effector pose for every move. In FANUC programming, you establish the TCP so the robot knows where the tool tip is relative to the robot flange, allowing all programmed Cartesian coordinates to be translated into correct joint motions. This ensures the tool reaches the intended location and orientation with precision; if the TCP is off, positions and angles will be off, risking inaccuracy or collisions. The other options describe things unrelated to how the tool’s geometry and pose are defined or used in motion planning.
