Semi-automatic tool compensation is a CNC feature for what?

• A. Tool offset entry
• B. Spindle speed control
• C. Toolpath generation
• D. Gage line measurement

Answer: (A)

Semi-automatic tool compensation is about applying tool offsets automatically during machining so the actual cutter position accounts for each tool’s size. You enter the tool offsets (diameter and length) into the machine’s offset table, and the CNC control uses those values to offset the tool center as the program runs. This lets you change tools or reuse tools without rewriting the program, while still achieving the correct final dimensions because the compensation continuously adjusts for the tool geometry. Spindle speed control, toolpath generation, and gage line measurement are separate functions: speed control sets rotation rate, toolpath generation plans the movement, and gage line measurement is a metrology step.
