CNC machining began to develop in the direction of fast and high efficiency, which includes the speed control of CNC machining. In order to make the most of the working schedule, it is necessary to speed up the moving components to a fast travel schedule in a very short time and stop them in a split second during the moving journey. That's why it's important to control the CNC machining speed.
1. Flexible acceleration and deceleration control
In CNC machining, the specific fully automatic speed control function is generally completed immediately by the system program. This must be through addition and subtraction manipulation to adjust the comprehensive acceleration and deceleration characteristics or change the CNC lathe program, the general user can not make the CNC lathe has the most ideal acceleration and deceleration characteristics according to their own preferences. Therefore, the proposed soft acceleration and deceleration control measures are based on the database principle, and the acceleration and deceleration manipulation is divided into two categories: acceleration and deceleration narrative and completion, and the acceleration and deceleration narrative is extracted from the system program.
2. Flexible and changeable automatic speed reduction control
For accelerated manipulation, it is necessary to store it in the acceleration and deceleration curve library file as a template in the form of a value table. The scientific and reasonable automatic acceleration and deceleration control of CNC machining is an important part of ensuring the dynamic characteristics of CNC lathes. The traditional automatic acceleration and deceleration operation according to the fixed immobility curve cannot ensure that the whole process of acceleration and deceleration is consistent with the characteristics of the CNC lathe because of the lack of coordination ability, and it is difficult to achieve the excellent dynamic performance of the fitness movement of the CNC lathe.
