The stability of the CNC system of woodworking engraving machine is very important. If the control system of wood engraving machine is unstable, such as the internal heating of the CNC system in summer, or the failure of the fan or hard disk, the CNC system can not work, the company needs to stop production for one week waiting for replacement. Or repair system, which is a serious loss for enterprises and manufacturers, woodworking engraving machine based on years of practical experience, summed up the following effective measures, hope to get users' reference and reference! Unstable factors include:
1. Software interpolation operation and Windows system Windows system is not a real-time operating system, suitable for office automation, but not suitable for industrial real-time numerical control, especially when the CNC system uses software for cutting and interpolation operations, the operator once cuts the inflection point Acceleration and deceleration at the beginning will immediately interrupt the cutting process.
2. High frequency CPU high frequency CPU has a large heat dissipation, must use a fan, often causes the CNC system to overheat in the summer.
3. Civil fan The civil fan runs in a harsh industrial environment such as dust and high temperature, which is inevitably worn and aged, and its service life is very limited. Once the fan is damaged, the CPU and motherboard will be damaged.
4. Civil large hard disk with mechanical rotating medium, high-speed rotation causes heat, vibration causes hard disk damage, easy to be infected with viruses, and instability is very high. All of the above are factors that cause the instability of the CNC system. How to overcome the unstable factors, Xiaobian gives you the following suggestions:
1. The hardware axis card interpolation operation replaces the software interpolation operation by the hardware axis card interpolation operation, so that the interpolation operation is performed on the bottom layer of the computer, that is, the axis card is not used, and the high-frequency CPU is not required.
2. The DOS operating system uses the single-task single-process DOS operating system to realize real-time CNC cutting through the hardware motion control axis card, avoiding the multi-tasking and multi-process of Windows causing the cutting interrupt to crash.
3. Fan-free, low-power, industrial-grade CPU uses a low-power CPU without a fan. Not only does the CPU have low heat, but it also eliminates the instability of the fan and effectively improves the stability of the CNC system.
