CNC exponential control machine tool is programmed and controlled by CNC processing language, usually G code. (CNC parts processing) CNC machining G code language tells CNC machine tools which Cartesian position coordinates to use for machining tools, and controls the feed speed and spindle speed of tools, as well as tool changer, coolant and other fuCNCtions. CNC machining has great advantages over manual machining, for example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be finished by manual machining.
CNC processing speed control measures:
1. Flexible acceleration and deceleration control:
In CNC machining, the system program usually directly realizes the specific automatic speed control fuCNCtion. In this way, the acceleration and deceleration characteristics of the system should be changed, or the CNC program should be modified through the addition and subtraction control, so that ordinary users can not make the acceleration and deceleration performaCNCe of the CNC machine tool according to their own wishes. Therefore, the flexible acceleration and deceleration control method proposed by us adopts the database priCNCiple, divides the acceleration and deceleration control into acceleration and deceleration description and execution, and separates the acceleration and deceleration description from the system program. In the CNC system software, a general control channel independent of the acceleration and deceleration database is designed, which can independently complete acceleration and deceleration calculation and trajectory control.
2. Flexible CNC processing automatic acceleration control:
Set the acceleration curve, analytical curve and non analytical curve, and store them as templates in the acceleration and deceleration curve library in the form of numerical tables.
3. Flexible CNC machining automatic deceleration control:
The acceleration control is stored in the acceleration and deceleration curve library as a template in the form of a digital table. Reasonable automatic acceleration and deceleration control is an important link to ensure the dynamic performaCNCe of CNC machine tools. The traditional automatic acceleration and deceleration control based on fixed curve is lack of flexibility, which is difficult to ensure the coordination between acceleration and deceleration process and machine tool performaCNCe, and also difficult to optimize the dynamic characteristics of machine tool movement.
