How to ensure the efficiency of CNC machining ?

CNC machining itself is to achieve automation, free manpower, improve work efficiency, and improve the quality of the workpiece. So how to ensure the efficiency of CNC machining?

  Under the premise of ensuring the smooth operation of the machine tool, the method that can make the acceleration and deceleration process the shortest time is the best solution to improve the speed of CNC machining, and it is also the most critical problem to study acceleration and deceleration.

  Generally, there are two different acceleration and deceleration control schemes: pre-acceleration and post-acceleration and deceleration: acceleration and deceleration control before interpolation and after interpolation preprocessing. We generally call it pre-acceleration control, interpolator and servo control. The feed rate that controls the motion axis before the device is generally referred to as post acceleration and deceleration. The algorithm of the post-acceleration and deceleration control is relatively simple compared to the pre-acceleration and deceleration. It is not necessary to calculate the deceleration point, but the servo gains of different axes are different, which is easy to affect the accuracy.

  At present, the CNC machining of Flytiger CNC is generally used for the front acceleration and deceleration control technology. The acceleration and deceleration control method can be reduced to the flexible acceleration and deceleration method and the traditional acceleration and deceleration method. The traditional acceleration and deceleration method has the methods of trapezoidal acceleration and deceleration and exponential acceleration and deceleration. The flexible acceleration and deceleration method has a trigonometric acceleration/deceleration method, an S-curve acceleration/deceleration method, and a polynomial acceleration/deceleration method. The traditional trapezoidal and exponential acceleration and deceleration affects the smoothness of motion due to the sudden change of acceleration. The flexible acceleration and deceleration is attracting attention in high-speed hardware processing due to the continuous acceleration.
