模具的制造加工过程不是一个步骤就能完成的，其中切削过程的进行关系到模具制造的质量案如何，而这个过程中还会采用很多方式方法，比如说洗铣方式。那么模具制造时如何选择采用顺铣还是逆铣呢？

　　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?

　　模具加工的切削过程少应分为粗加工、半精加工和精加工三个工序，在精加工过程中，将适用于圆刃铣刀和球头铣刀，圆刀片铣刀、球头立铣刀和直立铣刀都将应用余量铣削工艺，在每一道工序中，为下一道工序留出尽可能多的均匀分布的余量是非常重要的。通过选择槽形、特殊刀具尺寸和切削参数、组合和合适的铣削策略来优化切削工艺非常重要。

　　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.

　　那么模具加工中应该顺铣还是顺铣呢？山东模具制造厂家给出的答案是使用顺铣。切削刃刚切削时，顺铣时切屑厚度可达到很大值，顺铣时切屑厚度很低。一般而言，逆铣的刀具寿命比顺铣的短，因为发热量明显高于顺铣，顺铣随着切屑厚度从零增加到很大值，产生的热量也更多，因为切削刃上的摩擦力比铣削时强，而逆铣时径向力也明显较高，对主轴轴承产生不利影响。

　　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.

　　在顺铣中，切削刃主要承受压应力，这比逆铣中产生的拉力对硬质合金刀片或整体硬质合金刀具有更有利的影响。当然也有例外，当使用整体硬质合金立铣刀进行侧铣时，尤其是在硬化材料中，反向铣削是，这使得以较小的公差和较好的90度角更容易获得壁直度。

　　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.

　　如果不同轴向进给之间有任何错位，刀具连接标记也非常小，这主要是由于切削力的方向，如果在切割中使用非常锋利的刀刃，切割力会将刀“拉”向材料，可以反铣的另一个例子是用旧的手动铣床铣削，旧铣床的螺杆间隙大，反向铣削产生切削力间隙，使铣削动作更加稳定。

　　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.
