Five-axis linkage machining machine tools have strict requirements on NC interpolation controllers and servo drive systems. Why do you say this way? Next, let’s take a look at the strict requirements for five-axis simultaneous processing machine tools with the editor.

The motion of the five-axis linkage machining machine tool is the synthesis of the motion of the five coordinate axes. The addition of rotational coordinates not only increases the burden of interpolation operations, but also greatly reduces the rotational coordinate error. Therefore, the controller requires higher operating accuracy. The motion characteristics of five-axis machine tools require the servo drive system to have good dynamic characteristics and a large speed range.

In addition, the NC of five-axis CNC programs is particularly important. In order to improve processing efficiency, the traditional test cutting verification method must be eliminated. In five-axis CNC machining, the verification of CNC programs becomes very important because the workpieces processed by five-axis CNC machines are usually very expensive. In five-axis CNC machining, collisions are common problems, such as: the tool cuts into the workpiece, the tool collides with the workpiece at high speed, the tool collides with equipment within the processing range such as machine tools and fixtures, and the moving parts of the machine tool collide with fixed parts or workpieces.

In five-axis CNC, collisions are difficult to predict, and the calibration program must comprehensively analyze the machine tool kinematics and control system.
