Show answer and explanation

Correct answer: (D) Generate reference signals prescribing the shape of the produced part.

Explanation

The interpolator converts programmed path endpoints and geometry into coordinated intermediate axis-reference positions. Those reference signals prescribe the tool path and produced shape. **D**.
