模（mó）具的製造加工過程不是一（yī）個（gè）步驟就能完（wán）成的，其（qí）中切削過程的進行關係到模具製造的質量案如何，而這（zhè）個（gè）過程中還會采用很多方式方法（fǎ），比如（rú）說洗銑方式（shì）。那麽模具製造時如何選擇（zé）采用順銑還是逆銑呢？

　　Mold manufacturing process is not a step can be completed, the cutting process is related to the quality of mold manufacturing case, and this process will also use a lot of methods, such as washing and milling. So how to choose the use of down milling or reverse milling mold manufacturing?

　　模具加工的切削過程至少應分為粗加工、半精加工和精（jīng）加（jiā）工三個工序，在精加工過程中，將適用於（yú）圓刃銑刀和球頭銑（xǐ）刀，圓刀片銑刀、球頭（tóu）立銑刀和直立銑（xǐ）刀都將應用餘量銑削工藝，在每一道工序中，為下一道工序留出（chū）盡可（kě）能多的均（jun1）勻（yún）分布的餘量（liàng）是非（fēi）常（cháng）重要的。通過選擇槽形、特殊刀具尺寸和切削參數、品牌組合和合（hé）適的銑削（xuē）策略來（lái）優化切削工藝非常重要。

　　Mould processing cutting process should be divided into rough machining, semi-finishing and finish machining at least three working procedure, in the process of finishing, will apply to round head milling cutter, milling cutter and the ball round blade cutter, ball end mill and upright milling cutter will be allowance for the milling process, application in every working procedure, for the next procedure, set aside as much as possible the uniform distribution of allowance is very important. It is important to optimize the cutting process by selecting groove shapes, special tool sizes and cutting parameters, brand combinations, and appropriate milling strategies.

　　那麽模具加（jiā）工中應該順銑還是順銑呢？山東模具製造廠家給出的答案是使用順（shùn）銑。切削刃剛切削時，順銑（xǐ）時切屑厚度可達到很大值，順銑時切屑厚度很低。一般而言，逆銑的刀具壽命比順銑的短，因為發熱量明顯高於順銑，順銑隨著切屑厚度從零增加到（dào）很大值，產生的熱量也更多，因為切削刃上的摩擦力比銑削時（shí）強，而逆銑（xǐ）時徑向力也（yě）明顯較高，對主軸軸承產生不利影響。

　　So die processing should be along milling or along milling? Shandong die manufacturers give the answer is to use down milling. When the cutting edge is just cut, the chip thickness can reach a great value in down milling, while the chip thickness is very low in down milling. In general, the tool life of reverse milling is shorter than that of reverse milling, because the caloric value is significantly higher than that of reverse milling. With the increase of chip thickness from zero to a large value, the heat generated is also more, because the friction force on the cutting edge is stronger than that of milling, and the radial force of reverse milling is also significantly higher, which adversely affects the spindle bearing.

　　在順（shùn）銑中，切削刃主要（yào）承受壓應力，這比逆銑中產生的拉力對硬質合金刀片或（huò）整體硬質合金刀具（jù）有更有利（lì）的影響。當然也有例外（wài），當使用整（zhěng）體硬質合金立銑刀進行側銑時，尤其是在（zài）硬化材料中，反向銑削是首選，這使得以較小的公差和較好的（de）90度角更容易獲得壁直度（dù）。

　　In down milling, the cutting edge is mainly subjected to compressive stress, which has a more favorable effect on carbide blades or monolithic carbide knives than the tension generated in down milling. There are exceptions, of course, when a solid carbide end mill is used for side milling, especially in hardened materials, where reverse milling is preferred, which makes it easier to obtain wall straightness with smaller tolerances and a better 90 degree Angle.

　　如果不同軸向進給之間有任何錯位，刀具連接標記也非常（cháng）小，這主要是由（yóu）於切削力的方向，如果在切割中使（shǐ）用非常鋒利的刀刃，切割力會將刀（dāo）“拉”向材料，可以反銑的另一個例子是用舊（jiù）的手動銑床銑削，舊銑床的螺杆間隙大，反向銑削產生切（qiē）削力消除間隙，使銑削動作更加穩定。

　　If you don't have any mismatch between axial feed, cutting tool connection mark also is very small, this is mainly due to the direction of the cutting force, if using a very sharp blade in cutting, the cutting force will knife "pull" to the material, can be another example of the milling is to use the old manual milling machine milling, milling machine screw clearance is big, old reverse milling cutting force eliminate clearance, Make the milling operation more stable.
