Which concept describes the CNC feature for entering tool offsets?

• A. Semi-automatic tool compensation
• B. The database
• C. CAM
• D. Gage line

Answer: (A)

Entering tool offsets in a CNC machine is done through tool compensation, which adjusts the programmed path to account for the actual size and length of each tool. This feature lets the controller apply the correct offset automatically when a tool is selected, so the cutter follows the intended geometry. That makes semi-automatic tool compensation the best description here: you set up the tool dimensions in the tool data and the control applies those offsets during machining, typically with tool changes and compensation enabled. The other concepts don’t fit because the database is about storing data, not applying tool dimensions; CAM is about generating the toolpaths from a model rather than managing tool size offsets; and a gage line relates to measurement and inspection, not offset entry.
