How to avoid mechanical vibration and accuracy degradation caused by inertial forces during high-speed operation of a six axis reciprocating machine?

During high-speed operation, the inertia force of a six axis reciprocating machine can easily cause mechanical vibration and lead to a decrease in accuracy, seriously affecting the performance and processing quality of the equipment. To effectively avoid these problems, we can start from the following key aspects.

Optimizing the mechanical structure is the crucial first step. Reasonably design the mass distribution of each axis, reduce the mass of moving parts through lightweight design, and thus reduce the generation of inertial forces. For example, using high-strength and low-density aluminum alloy materials to manufacture shafts and connectors can reduce weight while ensuring mechanical strength. At the same time, enhancing the rigidity of mechanical structures is also crucial. By optimizing the design of supporting structures and reinforcing ribs, the overall vibration resistance of the structure can be improved. For example, using a thickened base and reinforced guide rail mounting seat to reduce displacement caused by vibration.

Improving control algorithms plays an important role in suppressing vibration and ensuring accuracy. Advanced motion control algorithms, such as adaptive control algorithms, can be used to dynamically adjust control parameters based on the real-time operating status of the equipment. During high-speed operation, the algorithm can automatically detect changes in inertia force and adjust the output torque and speed of the motor in a timely manner to maintain smooth motion. Introducing predictive control algorithms to predict possible vibrations and impacts during motion in advance, make adjustments in advance, and avoid the occurrence of vibrations.

Choosing appropriate buffering and damping devices can also effectively reduce the impact of inertial forces. Installing an elastic coupling between the motor and transmission components can buffer the impact generated during motor start and stop, reducing the impact on the mechanical structure. Add a damper between the guide rail and slider to dissipate vibration energy and suppress the propagation of vibration through damping. Using air springs or rubber damping pads as support for equipment can effectively isolate vibrations and improve equipment stability.

Regular maintenance and calibration of equipment are equally essential. Regularly inspect the connecting components of each axis to ensure that they are securely fastened and not loose, in order to avoid increased vibration caused by looseness. Lubricate and maintain the guide rails and sliders to reduce frictional resistance and ensure smooth movement. Regularly calibrate the accuracy of equipment, adjust deviations caused by vibration and wear in a timely manner, and ensure that the equipment is always in optimal operating condition.

During high-speed operation of a six axis reciprocating machine, various measures such as optimizing the mechanical structure, improving control algorithms, selecting appropriate buffering and vibration reduction devices, and regular maintenance and calibration can effectively avoid mechanical vibration and accuracy degradation caused by inertial forces, improve equipment efficiency and processing accuracy, and meet the high requirements of industrial production.
