Function of Interpolator in a CNC Machine Controller

The machining path in contouring systems is often built from a combination of circular and linear segments. The start and final locations of each segment's coordinates as well as the rate of feed only need to be specified in the component programme.

• Interpolation is the process of creating the needed shape as per this data, and the interpolator in CNC is the related software programme.
• To provide the necessary machining route, the interpolator coordinates motion in the machine axes, which are independently controlled.
• These motion of aixs are coordinated by an interpolator so that the predetermined path is always followed from the start of the movement to its conclusion.
• Circular and linear interpolators are the two most popular forms.
• Filling in the gaps between the key surrounds is the main definition of interpolation in computer science. It typically draws graphics semi-inevitably by estimating the in-between frames through the use of piecewise polynomial interpolation (typically).
• We can diverge the parameters by a certain age (the default PA controller) and particle velocity using interpolation controllers (ICs).

Summary:-

The Function of Interpolator in a CNC Machine Controller is to - 1. control spindle speed 2. coordinate feed rates of axes 3. control tool rapid approach speed 4. perform miscellaneous (M) functions (tool change, coolant control etc.)

In a CNC machine controller, the function of an interpolator is to coordinate feed rates of axes.
