CNC machining speed control method
CNC machining is developing towards high efficiency and high efficiency. These include CNC machining speed control. In order to maximize the efficiency of the working stroke, the moving parts must accelerate to the high-speed stroke in 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 idea of u200bu200bopen control, an automatic acceleration and deceleration control method for CNC machine tools based on arbitrary curves is proposed. The automatic acceleration and deceleration control technology is developed from the traditional fixed mode to a new flexible mode, which explores a new way to effectively improve the dynamic performance of CNC machine tools.
1. Flexible acceleration and deceleration control device:
In CNC machining, the specific speed automatic control function is generally realized directly by the system program. 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 the principle of database, which divides the 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, and can independently perform acceleration and deceleration calculation and trajectory control.
2. Automatic acceleration control system for flexible CNC machining:
The acceleration curve, analysis curve and non-analysis curve are established, and the They are stored in the acceleration and deceleration curve library as a value table as a template.
3. Automatic deceleration control system for flexible CNC machining:
The acceleration control is stored in the acceleration and deceleration curve library in the form of a digital table middle. Appropriate automatic acceleration and deceleration control is very important to ensure the dynamic performance of CNC machine tools. The traditional automatic acceleration and deceleration control based on fixed curve, due to lack of flexibility, it is difficult to ensure that the acceleration and deceleration process is coordinated with the performance of the machine tool, and it is difficult to optimize the dynamic characteristics of the machine tool movement.
