【Abstract】 A parabolic interpolation algorithm based on time division is developed in the article.And it has deduced the formulas in detail.Then the formulas has been simulated on the computer and proved that it is very efficient in the interpolating process of parabolic.This interpolating formula can be used in the middle or high quality specialized CNC system,and at the same time it has set up a solid base for CNC based open system.Therefore this interpolating formula has the certain function and expansion value.更多还原
