Abstract

The invention discloses a method for controlling the track of a numerically-controlled machine tool, and aims to solve the problem that the motion track of a machine tool cannot be accurately controlled and thus it is difficult to control the degree of parts machining. The displacement of a single movement in the machining plan is realized by being dispersed into M movements so that the variationof displacement for multiple times of close movements is reduced, the fitting degree of a machined free-form surface is better, and the degree of finish of the machined surface is higher. Therefore, the method disclosed by the invention can improve the degree of finish of the machined free-form surface, avoids the increase in data processing amount of the numerically-controlled machine tool and reduce the cost of the numerically-controlled machine tool under the same application requirement without lengthening a machining file. The method for controlling the machining track of a numerically-controlled machine tool has the advantages of simple steps, simple application and wide application scope, and is applicable to the field of numerically-controlled machining.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to a method for controlling the trajectory of a numerical control machine tool. Background technique [0002] Numerical control machining (Mumerical coMtrol machiMiMg) refers to a process method for processing parts on a numerical control machine tool. The process regulations of numerical control machine tool machining and traditional machine tool machining are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the movement of parts and tools. It is an effective way to solve the problems of variable variety, small batch, complex shape and high precision of parts and realize high-efficiency and automatic processing. The current CNC machining is gradually becoming intelligent, but it is still very difficult to control the trajectory of the CNC machine tool. How to control the trajectory of the mac...
