Three key points for controlling the speed of CNC machining

Dongguan CNC Precision Processing Factory is developing towards high speed and efficiency. This includes speed control for CNC machining. In order to fully utilize the effective working stroke, it is necessary to accelerate the moving parts to the high-speed stroke in a short time and stop them instantly during the high-speed stroke. This is why speed control is necessary for CNC machining.

1. Flexible acceleration and deceleration control

In the CNC machining of Dongguan, the specific automatic speed regulation function is generally directly implemented by the system program. In this way, it is necessary to change the acceleration and deceleration characteristics of the system or modify the CNC program through addition and subtraction control, so ordinary users cannot make the CNC machine tool have the best acceleration and deceleration performance according to their own needs. Desire. Therefore, our proposed flexible acceleration and deceleration control method adopts the database principle, dividing the acceleration and deceleration control into two parts: acceleration and deceleration description and implementation, and separating the acceleration and deceleration description from the system program. In the CNC system software, a universal control channel independent of the acceleration and deceleration database content was designed to independently complete acceleration and deceleration calculation and trajectory control.

2. Flexible automatic acceleration control

Set up acceleration curves, analytical curves, and non analytical curves, and store them as templates in the acceleration and deceleration curve library in the form of a digital table.

3. Flexible automatic deceleration control

The acceleration control is also stored as a template in the acceleration and deceleration curve library in the form of a digital table. Reasonable automatic acceleration and deceleration control is an important link to ensure the dynamic performance of CNC machine tools. The traditional Dongguan CNC precision machining plant lacks flexibility in automatic acceleration and deceleration control based on fixed curves, making it difficult to ensure the matching of acceleration and deceleration processes with machine tool performance and optimize the dynamic characteristics of machine tool motion.
