What aspects should the speed control of CNC machining start from?

CNC processing speed is becoming more and more efficient, but in order to improve the processing speed, we should also do a good job of control to ensure the smooth processing of the workpiece. What aspects should we start from?

1. Flexible acceleration and deceleration control

In CNC machining, the specific automatic speed control function is generally realized directly by the system program. In this way, to change the acceleration and deceleration characteristics of the system or add and subtract control to modify the numerical control program, so ordinary users can not according to their own will to make the numerical control machine tool with the best acceleration and deceleration performance. Therefore, the flexible acceleration and deceleration control method proposed by us adopts the principle of database, which divides acceleration and deceleration control into 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 independent of the acceleration and deceleration database is designed to complete the acceleration and deceleration calculation and trajectory control independently.

2. Flexible automatic acceleration control

The acceleration curve, analytical curve and non-analytical curve are set and stored in the acceleration and deceleration curve library in the form of number table as samples.

3. Flexible automatic deceleration control

As for acceleration control, it is stored in the acceleration and deceleration curve library as a sample in the form of a number table. Reasonable automatic acceleration and deceleration control is an important link to ensure the dynamic performance of CNC machine tools. Due to the lack of flexibility, the traditional automatic acceleration and deceleration control based on fixed curve is difficult to ensure the coordination between the acceleration and deceleration process and the performance of the machine tool, and it is difficult to achieve the optimal dynamic characteristics of the machine tool motion.

As we all know, CNC machining center is so far, no matter from the workpiece processing accuracy, processing efficiency, processing ability of complex workpiece and automation degree of performance is better a kind of CNC machining equipment, so in order to improve the workpiece processing efficiency must be controlled from the speed is also very important.
