1. The adsorption capacity of the machine itself is not good, the problem of adsorption and fixation of the whole board is not big, and it can not be adsorbed when processing small materials.

2、生產軟件生成的加工路徑不合理，應當遵循先切小板再切大板，先切沒有連接的地方再切有連接的地方，都是小板要從外邊往里面切，遵序的原理就是產品不是依靠本身的吸附力固定住自己，而是靠其它的板材去輔助固定的，注：加工實木的時候尤其要注意材料的紋理。

2. The processing path generated by the production software is unreasonable. It should follow the principle of cutting small plates first and then large plates, cutting the places where there is no connection first and then the places where there is connection. All small plates should be cut from the outside to the inside. The principle of order is that the product is not fixed by its own adsorption force, but by other plates, Note: when processing solid wood, pay special attention to the texture of the material.

3、加工結束后清潔不到位，臺面有細小的碎屑造成產品跟地板之間沒有有效的接觸，漏氣影響相對摩擦力造成跑板。

3. After processing, the cleaning is not in place, and there are small debris on the table, resulting in no effective contact between the product and the floor. Air leakage affects the relative friction, resulting in plate running.

4、加工時刀具過切量太大，臺面底板加工留下的深淺不一的刀痕，刀痕加工時會漏氣，造成材料跟底板之間吸附力小，同時造成接觸面小根據單位面積摩擦力公式，摩擦力等于摩擦因數乘以正向壓力，接觸面積減少，正向壓力減小，那么相對應的摩擦力也會隨之減小，在開料阻力不變的情況下去，摩擦力小于阻力就會造成跑板。

4. During machining, the tool overcut is too large, and the knife marks with different depths left by the machining of the table bottom plate will leak during the machining, resulting in small adsorption force between the material and the bottom plate and small contact surface. According to the friction formula per unit area, the friction is equal to the friction factor multiplied by the positive pressure, the contact area is reduced and the positive pressure is reduced, Then the corresponding friction will also decrease. When the cutting resistance remains unchanged, the friction less than the resistance will cause plate running.

5、真空泵自身負壓力能否達到需要的值，這個可以通過關掉吸附閥門的方式看真空壓力表數值，正常單獨測試應達到-0.7-1.2。吸附全開也要控制在-0.5以上，太低吸附力不夠。

5. Whether the negative pressure of the vacuum pump can reach the required value can be seen by closing the adsorption valve. The value of the vacuum pressure gauge shall reach -0.7-1.2 in normal separate test. The full opening of adsorption should also be controlled above - 0.5, which is too low and the adsorption force is not enough.

6、檢查吸附臺面與真空泵之間所有的連接處漏氣情況，還有底板邊緣是否有漏氣的情況。單獨開關一個吸附區測試吸力怎么樣。

6. Check whether there is air leakage at all connections between the adsorption table and the vacuum pump, and whether there is air leakage at the edge of the bottom plate. Open and close an adsorption zone separately to test the suction.

7、如果是在海拔相對較高區域，建議使用功率大一些的真空泵。

7. If it is in a relatively high altitude area, it is recommended to use a higher power vacuum pump.

8、臺面的結構是否合理決定真空吸附效果。功率同等的真空泵，不同規格的臺面的吸附效果是不同的。

8. Whether the structure of the table is reasonable or not determines the vacuum adsorption effect. With the same power vacuum pump, the adsorption effect of different specifications of table top is different.

9、刀具選擇不合理，刀具鈍化嚴重，在成切割阻力大。

9. The tool selection is unreasonable, the tool passivation is serious, and the cutting resistance is large.
