Mathematical control 5 axis CNC horizontal milling machine has many variables that cause oscillation. In addition to the transmission void, elastic contortion, friction resistance and also other aspects that cannot be removed at the mechanical degree, the influence of the pertinent criteria of the servo system is additionally a key facet.
We can eliminate the vibration of the 5-axis CNC horizontal milling machine from the following aspects.
1. Lower the gain of the position loop.
2. Oscillation triggered by closed-loop servo system.
3. Use high frequency suppression feature.
1. Lower the gain of the position loop
Symmetrical calculus is a multifunctional controller. It cannot just effectively get proportional gain to present as well as voltage signals, yet also can readjust the outcome signal to lag into a leading trouble. Oscillation faults are often brought on by the lagging of the result present and also voltage right into leading problem. Right now, PID can be utilized to readjust the output current as well as voltage phase.
2. Oscillation triggered by closed-loop servo system
Some CNC servo systems make use of semi-closed loophole gadgets, and the fully closed loop servo system should change the specifications under the precondition that the regional semi-closed loop system does not generate oscillation, so the two are similar.
3. Use high frequency suppression feature
The above conversation is associated with the specification optimization method of low-frequency oscillation, as well as occasionally the CNC system of the 5 axis CNC horizontal milling machine will have high-frequency harmonics in the comments signal due to some vibration aspects on the machinery, which makes the outcome torque not consistent. Subsequently, vibration is created. For such high-frequency oscillation problems, a first-order low-pass filter web link can be included in the rate loop, which is a torque filter.
Which aspects should be paid attention to when making use of 5 axis CNC horizontal milling machine?
1. The tools operation and maintenance workers have to be specialists that have the expert understanding of the corresponding equipment or personnel that have actually passed expert technical training, and also should operate the 5 axis CNC horizontal milling machine according to the safe operation procedure as well as safe procedure needs;
2. Non-professionals are not permitted to open up the electric cupboard door. Before opening the electrical cupboard door, see to it that the primary power switch of the devices has actually been switched off. Only expert upkeep workers are enabled to open the door of the electrical closet for power-on upkeep;
3. Except for some parameters that can be modified by the individual, the remainder of the system specifications, pin specifications, servo criteria, etc., cannot be modified by the individual without permission, or else it will cause damages to the driver's tools, parts, and also personnel;
4. After changing the specifications, when carrying out a handling, the 5 axis CNC horizontal milling machine will be made use of for test procedure with equipment securing, solitary block and also other techniques without tools and parts set up, and afterwards utilize the tools after verifying that the devices are typical;
5. It is advised that the constant procedure of the devices must not go beyond 24 hours. If the continual procedure time is too long, it will impact the service life of the electrical system and also some mechanical parts, and after that impact the accuracy of the equipment;
6. All adapters, joints, and so on of the 5 axis CNC horizontal milling machines are not permitted to be removed or plugged in, otherwise it will cause severe consequences.
