Question:

In NC machine, the function of interpolator is to

Show Hint

The interpolator in NC machines ensures that the tool moves precisely according to the programmed shape, which includes generating reference signals for tool movement.

The Correct Option is D

Solution and Explanation

- The interpolator in a Numerical Control (NC) machine is responsible for generating the correct reference signals that guide the tool's movement along the intended path. The interpolator computes the required coordinates and ensures that the tool follows the desired trajectory based on the input data.
- Therefore, the interpolator's primary function is to generate reference signals that describe the shape of the part being produced.
