    銑刀剛性要好對回收有什么價值?

    二是為適應數控銑床加工過程中難以調整切削用量的特點。例如,當工件各處的加工余量相差懸殊時,通用銑床遇到這種情況很容易采取分層銑削方法加以解決,而數控銑削就必須按程序規定的走刀路線前進,遇到余量大時無法象通用銑床那樣“隨機應變”,除非在編程時能夠預先考慮到,否則銑刀必須返回原點,用改變切削面高度或加大刀具半徑補償值的方法從頭開始加工,多走幾刀。

    Second, it is difficult to adjust the cutting parameters in the machining process of NC milling machine. For example, when the machining allowance of the workpiece varies greatly, the general milling machine can easily adopt the layered milling method to solve this situation, while the NC milling must move forward according to the tool path specified in the program. When the allowance is large, it cannot be "random strain" like the general milling machine. Unless it can be considered in advance during programming, the milling cutter must return to the origin, Start machining from scratch by changing the height of the cutting surface or increasing the compensation value of the tool radius.
    但這樣勢必造成余量少的地方經常走空刀,降低了生產效率,如刀具剛性較好就不必這么辦。再者,在通用銑床上加工時,若遇到剛性不強的刀具,也比較容易從振動、手感等方面及時發現并及時調整切削用量加以彌補,而數控銑削時則很難辦到。在數控銑削中,因銑刀剛性較差而斷刀并造成工件損傷的事例是常有的,所以解決數控銑刀的剛性問題是至關重要的。

    However, this is bound to cause empty knives in places with less margin, which reduces the production efficiency. If the tool rigidity is good, it is not necessary to do so. Moreover, when machining on a universal milling machine, if you encounter a tool with weak rigidity, it is easier to find and adjust the cutting parameters in time from the aspects of vibration and hand feeling, while it is difficult to do it in NC milling. In NC milling, it is common to break the cutter and cause workpiece damage due to poor rigidity of milling cutter, so it is very important to solve the rigidity problem of NC milling cutter.
    銑刀的耐用度要高
    The durability of milling cutter should be high
    其是當一把銑刀加工的內容很多時,如刀具不耐用而磨損較快,就會影響工件的表面質量與加工精度,而且會增加換刀引起的調刀與對刀次數,也會使工作表面留下因對刀誤差而形成的接刀臺階,降低了工件的表面質量。
    When a milling cutter has many processing contents, such as the tool is not durable and wears quickly, it will affect the surface quality and machining accuracy of the workpiece, increase the times of tool adjustment and tool setting caused by tool change, leave the tool receiving step formed by tool setting error on the working surface, and reduce the surface quality of the workpiece.
    上述兩點之外,銑刀切削刃的幾何角度參數的選擇及排屑性能等也非常重要,切屑粘刀形成積屑瘤在數控銑削中是十分忌諱的??傊?,根據被加工工件材料的熱處理狀態、切削性能及加工余量,選擇剛性好,耐用度高的銑刀,是充分發揮數控銑床的生產效率和獲得滿意的加工質量的前提。
    In addition to the above two points, the selection of geometric angle parameters and chip removal performance of the cutting edge of the milling cutter are also very important. Chip sticking to the cutter to form chip accumulation tumor is very taboo in NC milling. In short, according to the heat treatment state, cutting performance and machining allowance of the workpiece material to be machined, selecting a milling cutter with good rigidity and high durability is the premise to give full play to the production efficiency of the NC milling machine and obtain satisfactory machining quality.
