Speed control method for numerical control multilayer leather cutting machine tool

Abstract

The invention discloses a speed control method for a numerical control multilayer leather cutting machine tool, comprising the following steps of: (1) setting the numerical control multilayer leather cutting process including a main motion and a feed motion; and for the speed control on the feed motion, figuring out the acceleration Ja of the machine tool and deducting an acceleration formula anda speed calculation formula according to performance indexes of the feed maximum acceleration amax and the feeding maximum speed Vmax; (2) judging whether a leather material to be processed is a standard leather material or not and correcting; (3) judging whether the layer number of leather to be cut is a single layer or not and correcting; and (4) judging whether the current cutting track is a straight line or not: correcting the speed according to the radius Rx of a current path to obtain V3 and linearly calculating according to the speed in a path curvature radius interval to obtain the cutting speed of any curvature radius. The speed control on the tangential accompany motion can be realized. The speed control method is suitable for multilayer leather processing occasions and has highprocessing speed and efficiency optimizing degree; and the adjust error is reduced.

Description

technical field [0001] The invention relates to the field of multilayer leather numerical control cutting machine tools, in particular to a speed control method for multilayer leather numerical control cutting machine tools. Background technique [0002] CNC cutting technology includes the most advanced mechanical technology, computer and information processing technology, system technology, automatic control technology, sensing and detection technology, and servo transmission technology. With the development of numerical control technology, numerical control cutting technology is gradually developing in the direction of openness, intelligence and high speed. The foreign leather cutting system has developed into an integrated and intelligent CNC integrated system. However, although the foreign advanced CNC leather cutting machine is powerful, it is expensive, and adopts a technology monopoly and closed policy to our country. [0003] For this speed planning method, relevant...
