A New Point-by-point Comparison Method of Linear Interpolation to Realize Two-axis

Point-by-point Comparison interpolation is one method of the contour interpolation algorithms ,ever used widely in CNC machine tools ,but its being not to realize two-axis limits its application .In this paper , A new Point-by-point Comparison Method of Linear Interpolation is put forward ,and this new algorithm not only overcomes it disadvantage and realize two-axis, but also improves the accuracy of the interpolation to some extent, While maintaining its original merits.
