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.軟件插補運算與Windows系統Windows系統不是實時操作系統，適用于辦公自動化，但不適用于工業實時數控控制，尤其是當數控系統使用軟件進行切割插補運算時，操作者一旦在切割拐點處進行加減速操作，就會立即導致切割過程中斷。

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.高主頻CPU高主頻CPU散熱量大，必須使用風扇，在夏季經常導致數控系統過熱。

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.民用風扇民用風扇在粉塵高溫等惡劣工業環境運行，必然磨損老化，使用壽命非常有限。一旦風扇損壞，必然導致CPU和主板損壞。

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.民用大硬盤帶機械旋轉介質，高速旋轉導致發熱，震動導致硬盤損壞，易感 染病 毒，不穩定性非常高。以上都是造成數控系統不穩定的因素，如何克服不穩定因素，維宏給您提以下幾點建議：

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.硬件軸卡插補運算通過硬件軸卡插補運算替代軟件插補運算，使插補運算在計算機底層即軸卡上進行，不使用Windows系統，不需要高主頻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操作系統使用單任務單進程的DOS操作系統，通過硬件運動控制軸卡實現實時數控切割，避免Windows多任務多進程導致切割中斷死機，并通過使用維宏數控系統的“一鍵式”自動切割工藝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.免風扇、低功耗、工業級CPU使用不帶風扇的低功耗CPU，不僅CPU發熱低，而且風扇的不穩定性，有用提高數控系統的穩定性。

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.
