How to eliminate oscillation of CNC lathe

There are many reasons for oscillation. In addition to the mechanical transmission gap, elastic deformation, friction resistance and many other factors, the influence of relevant parameters of the servo system is also important. 1. Reduce the position loop gain.

The proportional calculus integrator is a multi-functional controller. It can not only effectively perform proportional gain on the current and voltage signals, but also adjust the output signal from lagging to . Oscillation faults are sometimes caused by the output current and voltage lagging to . At this time, the output current and voltage phase can be adjusted through PID.

2. Oscillation caused by closed-loop servo system

Some CNC servo systems use semi-closed-loop devices, while fully-closed-loop servo systems must adjust parameters on the premise that the local semi-closed-loop system does not oscillate, so the two are similar.

3. Adopt high frequency suppression function

The above discussion is about the parameter optimization method during low-frequency oscillation, and sometimes the CNC system will produce feedback signals containing high-frequency harmonics due to certain mechanical oscillation reasons, which makes the output torque unstable and causes vibration. For this high-frequency oscillation situation, a -order low-pass filter link can be added to the speed loop, which is a torque filter.

In the realm of modern manufacturing, the Precision Multi-Axis CNC Milling Machine stands as a testament to technological innovation and engineering prowess. This sophisticated tool has revolutionized the way intricate components are fabricated across various industries, offering unmatched precision, versatility, and efficiency.

To understand the creation of the Precision Multi-Axis CNC Milling Machine, we must first delve into the origins of CNC (Computer Numerical Control) technology. The concept of CNC dates back to the 1940s and 1950s when early numerical control systems were developed to automate machining processes. These systems relied on punched tape to control the movement of machine tools, laying the groundwork for more advanced CNC technologies that would follow.

Early Development

The development of CNC milling machines evolved significantly during the 1960s and 1970s. Innovators and engineers began integrating digital computers with machine tools to enable precise control over movements and operations. This transition marked a pivotal shift from manual to automated machining processes, enhancing accuracy and repeatability in manufacturing operations.

Introduction of Multi-Axis Capability

The evolution towards Multi-Axis CNC Milling Machines gained momentum in the 1980s and 1990s. Traditional milling machines with three axes (X, Y, Z) were enhanced to incorporate additional rotational axes (A, B, C), enabling complex machining operations. This multidimensional capability allowed manufacturers to produce intricate geometries and contours that were previously challenging or impossible with conventional machining methods.

Advancements in Control Systems

Central to the development of Precision Multi-Axis CNC Milling Machines was the continuous improvement in CNC control systems. Modern machines are equipped with sophisticated software and controllers that facilitate seamless integration of CAD (Computer-Aided Design) models with CAM (Computer-Aided Manufacturing) programming. This integration enables operators to generate tool paths, simulate machining processes, and optimize cutting strategies with precision and efficiency.

Materials and Tooling Innovations

Alongside advancements in CNC technology, innovations in materials and tooling have also played a crucial role in shaping the capabilities of Multi-Axis CNC Milling Machines. High-performance cutting tools made from carbide, ceramic, and diamond coatings have improved machining speeds and tool longevity, while advancements in materials science have expanded the range of workpiece materials that can be effectively machined.
