The stability of the numerical control system of woodworking engraving machine is very important. If the control system of woodworking engraving machine is unstable, for example, in summer, the numerical control system cannot work due to internal heating of the numerical control system or damage to the fan or hard disk, the enterprise needs to stop production for a week to wait for the system to be replaced or repaired, which will be a serious loss to the enterprise and manufacturer, According to many years of practical operation experience, ink source summarizes the following useful measures, hoping to get users' reference! Unstable factors include:

1.软件插补运算与Windows系统Windows系统不是实时操作系统，适用于办公自动化，但不适用于工业实时数控控制，尤其是当数控系统使用软件进行切割插补运算时，操作者一旦在切割拐点处进行加减速操作，就会立即导致切割过程中断。

1. Software interpolation operation and windows system Windows system is not a real-time operating system, which is suitable for office automation, but not for industrial real-time NC control. Especially when the NC system uses software for cutting interpolation operation, once the operator performs acceleration and deceleration operation at the cutting inflection point, the cutting process will be interrupted immediately.

2.高主频CPU高主频CPU散热量大，必须使用风扇，在夏季经常导致数控系统过热。

2. High main frequency CPU high main frequency CPU has large heat dissipation, so fan must be used, which often leads to overheating of CNC system in summer.

3.民用风扇民用风扇在粉尘高温等恶劣工业环境运行，必然磨损老化，使用寿命非常有限。一旦风扇损坏，必然导致CPU和主板损坏。

3. Civil fans civil fans will inevitably wear and age when they operate in harsh industrial environments such as dust and high temperature, and their service life is very limited. Once the fan is damaged, the CPU and motherboard will be damaged.

4.民用大硬盘带机械旋转介质，高速旋转导致发热，震动导致硬盘损坏，易感 染病 毒，不稳定性非常高。以上都是造成数控系统不稳定的因素，如何克服不稳定因素，维宏给您提以下几点建议：

4. Large civil hard disk is equipped with mechanical rotating medium. High speed rotation leads to heating, vibration leads to hard disk damage, easy to infect virus and high instability. The above are the factors that cause the instability of the CNC system. How to overcome the unstable factors, Weihong gives you the following suggestions:

1.硬件轴卡插补运算通过硬件轴卡插补运算替代软件插补运算，使插补运算在计算机底层即轴卡上进行，不使用Windows系统，不需要高主频CPU。

1. The hardware axis card interpolation operation replaces the software interpolation operation through the hardware axis card interpolation operation, so that the interpolation operation is carried out on the bottom layer of the computer, i.e. the axis card, without windows system and high main frequency CPU.

2.DOS操作系统使用单任务单进程的DOS操作系统，通过硬件运动控制轴卡实现实时数控切割，避免Windows多任务多进程导致切割中断死机，并通过使用维宏数控系统的“一键式”自动切割工艺替代手工操作切割方式。

2. DOS operating system uses DOS operating system of single task and single process to realize real-time NC cutting through hardware motion control axis card, so as to avoid cutting interruption and crash caused by windows multi task and multi process, and replace manual cutting mode by using "one key" automatic cutting process of Weihong NC system.

3.免风扇、低功耗、工业级CPU使用不带风扇的低功耗CPU，不仅CPU发热低，而且风扇的不稳定性，有用提高数控系统的稳定性。

3. Fan free, low-power, industrial CPU using low-power CPU without fan not only has low CPU heating, but also eliminates the instability of fan, which is useful to improve the stability of CNC system.
