Abstract
The invention provides a method for measuring the distance between a cutter mounting end surface and a rotating center during numerical control machining. The method comprises the following steps of: mounting a cylinder on a machining main shaft, and measuring the diameter phi of the cylinder and the distance Lt between the outer end surface of the cylinder and the cutter mounting end surface; and then measuring the Z and Y direction coordinates of the outer end surface of the cylinder and the Z and Y direction coordinates of the cylindrical surface of the cylinder when the machining main shaft is in a vertical state and a horizontal state, and calculating the distance between the cutter mounting end surface and the rotating center through a formula. By the method provided by the invention, the distance between the cutter mounting end surface and the rotating center can be convenient to measure without special equipment and professionals, and the length of a machining cutter is convenient to obtain. At the same time, the method for measuring distance between the cutter mounting end surface and the rotating center at one time can be used to measure the length of a plurality of machining cutters.
