Point by point comparison method of straight lines is widely used in CNC, but the traditional point by point comparison method exists some weaknesses such as high interpolation error, low feed speed, uneven pulse distribution.For above problems, an new point by point comparison method of straight lines is given. Based on pulse quadrilateral, compared with the traditional point by point comparison method of line interpolation, the interpolation accuracy is increased by 50%, the feed speed is increased by 38.89%. In addition, the pulse distribution is also more uniform.
