1. Flexible acceleration
In CNC machining, specific automatic speed control functions are implemented by system programs. Generally speaking, the flexible acceleration and deceleration control methods are based on the database principle. Normally, the acceleration and deceleration control can be divided into two parts: acceleration and deceleration description and implementation. It requires separating the acceleration and deceleration description from the system program. In the numerical control system software, it is generally possible to use a general-purpose control channel that has nothing to do with the contents of the acceleration and deceleration database, so that it can independently complete the acceleration and deceleration calculation and trajectory control.
2. Flexible automatic deceleration control
Acceleration control can generally be stored in the acceleration and deceleration curve library in the form of a number table according to the template. Reasonable automatic acceleration and deceleration control is a very important link that can ensure the dynamic performance of CNC machine tools. Traditional fixed curve-based automatic acceleration / deceleration control generally lacks flexibility. It is not easy to ensure that the acceleration and deceleration process and the performance of the machine tool are compatible with each other. Therefore, the speed is not controlled. This is difficult to make the dynamic characteristics of the machine tool reach the optimal state .
In a word, Reasonable automatic acceleration and deceleration control is an important link to ensure the dynamic performance of CNC machine tools
