To compensate for varying tool sizes describes the purpose of which offset?

• A. Tool length offset
• B. The database
• C. The gage line
• D. CAM

Answer: (A)

Tool length offset is used to account for differences in how long each tool actually is. The CNC controller keeps a length value for every tool, and when a tool is selected, that offset is added to the programmed Z position so the tip reaches the intended depth regardless of tool length. This lets the same program work with tools of different lengths, as long as the offsets are accurate. The other terms aren’t used for this purpose: the database stores tool data, CAM is software for creating toolpaths, and a gage line is an inspection reference rather than a method to adjust tool reach.
