How would you define 'tool offset' in CNC milling?

• A. Adjustment of machine speed
• B. Adjustment made for cutter dimensions
• C. Distance between tool and workpiece
• D. Angle adjustment of the cutting tool

Answer: (B)

Tool offset in CNC milling refers to the adjustment made for cutter dimensions. This offset compensates for the physical dimensions of the tool being used, ensuring that the CNC machine knows the precise location of the tool relative to the workpiece. Each tool has a different diameter, length, or geometry, and these variations must be accounted for to achieve accurate machining results. By properly setting the tool offsets, programmers can ensure that the tool cuts at the correct position, leading to precise machining and the desired final dimensions of the workpiece. This adjustment is crucial during the setup of a CNC milling operation, as it enables the machine to accurately position the tool based on its specific characteristics. By understanding and correctly applying tool offsets, operators can minimize errors and enhance the quality of the finished product.
