Problems solved by technology

At this time, it is difficult to meet the needs of the processing technology if the constant line speed is used to cooperate with the feed.
Not only that, in the new process requirements, the synchronous control law of the feed rate of each axis and the main rotary axis is also more complicated
As a result, the calculations performed by the CNC system are too complex and require high computing resources.

Abstract

The invention relates to a control method and device for a numerical-control machine tool. The control method comprises that programming points related to a first program are obtained, the first program is used to execute a numerical control system of the numerical-control machine tool so that an operation including processing of a first interpolation track is completed, and the programming pointscomprise position information representing the first interpolation track; the programming points are loaded in a storage space associated with the numerical control system; and in response to a programming point feeding start instruction in the first program, programming points are obtained from the storage space, an interpolation program in the numerical control system is skipped, and the obtained programming points are output to a driver of the numerical control system according to a predetermined period. The invention also describes a corresponding device, a computer system and a readablestorage medium.

Description

technical field [0001] The present invention generally relates to the field of intelligent manufacturing, and particularly relates to a control method, device and system for a numerically controlled machine tool. Background technique [0002] The feeding methods in the existing CNC system are usually divided into sub-feed and rotary feed. Among them, sub-feed is a commonly used speed control method in milling and drilling. The programmer controls the feed rate by the incremental movement of the tool relative to the workpiece to be machined within a given unit of time (eg, per minute). However, sub-feeding cannot meet the needs of all processing scenarios. For example, in the turning process of the rotary surface, the surface quality of the workpiece is closely related to the feed increment and uniformity of each axis per revolution of the spindle, so when programming, the feed rate is directly controlled by the rotary feed method It is more intuitive and convenient, and c...
