With our technology is in continuous progress, of course progress, it requires a certain processing method to be able to process, otherwise it is not processed, CNC processing is also the same, so what is the acceleration and deceleration control of CNC processing?
1. The basic idea of flexible acceleration and deceleration control
In CNC processing, generally by the system program directly to achieve a specific automatic acceleration and deceleration control function. In this way, to change the system acceleration and deceleration characteristics or acceleration and deceleration control to modify the CNC program, and thus the ordinary user can not make the CNC machine according to their own wishes to have the best acceleration and deceleration performance. Therefore, our proposed flexible acceleration/deceleration control method uses the principle of database to divide the acceleration/deceleration control into two parts: acceleration/deceleration description and implementation, and separates the acceleration/deceleration description from the system program. In the CNC system software, a common control channel independent of the acceleration and deceleration database content is designed, and the acceleration and deceleration calculation and trajectory control are completed independently by it.
2. Flexible automatic acceleration control
Set acceleration curves, analysis curves and non-analysis curves, and store them as samples in the acceleration/deceleration curve library in the form of a number table.
3. Flexible automatic deceleration control
The acceleration control is also stored in the acceleration/deceleration curve library as a sample in the form of a number table. Reasonable automatic acceleration and deceleration control is an important part of ensuring the dynamic performance of CNC machine tools. Traditional automatic acceleration and deceleration control based on fixed curves due to the lack of flexibility, it is not easy to ensure that the acceleration and deceleration process with the machine performance, it is difficult to make the dynamic characteristics of machine motion to achieve the best.
