PROBLEM TO BE SOLVED: To provide a linear interpolation method for simplifying a driving control device hardware required for interpolation, quickly executing interpolation, and making the other axis follow a reference axis accurately. SOLUTION: The linear interpolation for driving control device sets the speed of the reference axis by selecting the reference axis based on the commanded value Xp, Yp, Zp, and Wp of the driving quantity with a reference axis setting part 30, sets the speed of the other axis in such a way as the ratio of the speed of the reference axis to the speed of the other axis becomes the ratio of the respective driving quantities with an other axis speed calculating part 31, drives the reference axis and the other axis based on the set speed via a driving pulse generating part 3 to 6, and increases and decreases the speed of the other axis by constant value by calculating theoretical value of the driving quantity of the other axis with a theoretical value calculating part 32 in a predetermined period by detecting the difference of the actual movement and the theoretical value, and deciding the increase and decrease of the compensation to cancel the difference with a speed compensation deciding part 33.
