Control method of CNC machining speed

CNC processing is developing in a direction of high efficiency and high efficiency. This includes CNC machining speed control. To maximize the working stroke, the moving parts must accelerate to the high-speed stroke within a short time and stop immediately during the high-speed stroke. Therefore, it is necessary to control the machining speed of the CNC machining center.

Based on the open control idea, a CNC machine tool automatic acceleration and deceleration control method based on arbitrary curve is proposed. The automatic acceleration and deceleration control technology has been developed from the traditional fixed mode to the new flexible mode, and a new way to effectively improve the dynamic performance of CNC machine tools has been explored.

1. Flexible acceleration and deceleration control device:

In CNC processing, the system program is generally used to directly implement specific speed automatic control functions. In this way, the acceleration and deceleration characteristics of the system can be changed, and the CNC program can be modified through the addition and subtraction control, so that ordinary users cannot make the CNC machine tool have the best acceleration and deceleration performance according to their own wishes. To this end, we propose a flexible acceleration and deceleration control method based on database principles, which divides acceleration and deceleration control into acceleration and deceleration description and execution, and separates it from the system program. The software designs a general control channel independent of the acceleration and deceleration database, which can independently perform acceleration and deceleration calculation and trajectory control.

2. Automatic acceleration control system for flexible CNC machining:

Acceleration curves, analytical curves and non-analytical curves are established and stored as a numerical table as a template in the acceleration and deceleration curve library.

3. Automatic speed reduction control system for flexible CNC machining:

Acceleration controls are stored in the acceleration and deceleration curve library as digital tables. Appropriate automatic acceleration and deceleration control is crucial to ensuring the dynamic performance of CNC machine tools. Traditional automatic acceleration and deceleration control based on fixed curves is difficult to ensure that the acceleration and deceleration process is coordinated with the machine tool performance due to the lack of flexibility, and it is also difficult to optimize the dynamic characteristics of the machine tool movement.

All the above are methods to control the CNC processing speed. I hope it can help you. If you want to know more about CNC processing, please consult online or call our service hotline (the upper right corner of the website), and we will do our best to do it. You provide high-quality service!
