What is the acceleration and deceleration control of CNC machining?

With the continuous advancement of our technology, of course, we need a certain processing method to be able to process it, otherwise it cannot be processed. The same is true for CNC processing. So what is the acceleration and deceleration control of CNC processing?

1. The basic idea of u200bu200bflexible acceleration and deceleration control

In CNC machining, the specific automatic acceleration/deceleration control function is usually realized directly by the system program. In this mode, it is necessary to change the system's acceleration and deceleration characteristics or add and subtract control to modify the CNC program, so ordinary users cannot make the CNC machine tool have the best acceleration and deceleration performance according to their own wishes. Therefore, the flexible acceleration and deceleration control method we proposed adopts the principle of the database, and divides the acceleration and deceleration control into two parts: acceleration and deceleration description and implementation, and separates the acceleration and deceleration description from the system program. In the numerical control system software, a general control channel that has nothing to do with the content of the acceleration and deceleration database is designed, and the acceleration and deceleration calculation and trajectory control are completed independently by it.

2. Flexible automatic acceleration control

Set acceleration curves, analytical curves and non-analytic curves, and store them in the acceleration and deceleration curve library in the form of a number table as a model.

3. Flexible automatic deceleration control

Acceleration control will store it in the acceleration and deceleration curve library in the form of a number table as a model. Reasonable automatic acceleration and deceleration control is an important link to ensure the dynamic performance of CNC machine tools. The traditional automatic acceleration and deceleration control based on a fixed curve lacks flexibility, and it is not easy to ensure that the acceleration and deceleration process matches the performance of the machine tool, and it is difficult to optimize the dynamic characteristics of the machine tool movement.
