Which of the following is NOT a method for establishing a TOOL frame?

The five-point method is not a recognized method for establishing a TOOL frame in FANUC robotics. The TOOL frame defines the robot's tool position and orientation relative to its base frame and is essential for accurate movements and operations.

The three-point method is commonly used as it requires the measurement of three distinct points on the tool to establish its orientation in space. The six-point method provides even more precision by utilizing six points, allowing for an enhanced definition of tool geometry. Similarly, the four-point method finds its application in situations requiring a balance between complexity and data accuracy, as it captures four points.

In contrast, the five-point method lacks a specific standard application within the FANUC framework, making it the outlier among the established methods for defining a TOOL frame. This distinction highlights the importance of using accepted techniques to ensure accurate robotic operations.
