Definitions for "Linear Interpolation"
The mathematical process the CNC controller performs to determine the time and distance each axis must move to insure a perfectly straight tool movement regardless of angle. G1 is the CNC programming word for linear interpolation under feed control. Example G1 X3Y-1F10.0 where F controls the feed rate.
A form of interpolation that uses the calculated mean of two sample points as the interpolated sample point See also: drop-sample conversion
A method that allows the prediction of an unknown value if any two particular values on the same scale are known and the rate of change is assumed constant.
