Abstract

The invention discloses an acceleration and deceleration controlling method based on an S-shaped curve. An S-shaped curve is applied to speed planning of an i+1 section of a processing track, wherein the i+1 section of the processing track is arranged between a first transfer position and a second transfer position, and accelerations of the first transfer position and the second transfer position are controlled not to be zero. The invention further discloses a controlling device of acceleration and deceleration based on the S-shaped curve and the numerically-controlled machine tool. Due to the fact that the acceleration and deceleration method based on the S-shaped curve and the equipment using the acceleration and deceleration controlling method based on the S-shaped curve of a numerically-controlled system control the accelerations of the first transfer position and the second transfer position not to be zero, processing efficiency can be effectively improved, and impact to the machine tool during the processing process is reduced.

Description

technical field [0001] The invention relates to the technical field of numerical control systems, in particular to an S-shaped curve-based acceleration and deceleration control method and device, and also relates to a numerical control machine tool using the acceleration and deceleration control device. Background technique [0002] With the development of high-speed cutting technology, the trend of high-speed machining of CNC machine tools has become increasingly prominent. Due to the variety of workpiece contours to be processed, the processing program of each part consists of multiple program segments. Most of these program segments are composed of straight lines and arcs, and there are transitions where the straight lines and arcs are connected. In order to realize the high precision of workpiece processing, CNC machine tools must perform acceleration and deceleration processing in the motion control between the program segments at the transition, so as to ensure that t...
