By point contact machining, we mean to form point contact machining by grinding spherical milling cutter, spherical grinding wheel, etc. The main characteristics of this kind of machining are: the spherical normal vector points to the whole space, it has adaptability to the surface normal vector processing, and the line and surface contact processing is relatively simple, its programming and calculation are relatively simple, as long as the tool radius is less than the curvature radius of the surface, interference can be avoided. So it is suitable for all kinds of surface treatment. However, due to contact forming, the cutting speed is close to zero, the cutting conditions are poor, and the machining accuracy and efficiency are low.

我们所说的表面接触加工，就是指通过表面接触形成诸如磨削加工等加工方法。这种加工的主要特点是：由于切割点的切削速度快，所以循环进给量大，加工效率高，加工精度高。但是，由于模具的成型方法和刀具的形状，它主要适用于平面上加工曲面的凸性曲线变化。

By surface contact machining, we mean to form machining methods such as grinding by surface contact. The main characteristics of this kind of machining are: because the cutting speed of the cutting point is fast, so the circulation feed rate is large, the machining efficiency is high, and the machining precision is high. However, due to the forming method of the mold and the shape of the cutter, it is mainly suitable for the convexity curve change of the machining surface on the plane.

线接触加工是指在加工过程中与线接触的过程，例如柱形周铣、锥形周铣、凸轮轴钻、带磨等。其特点是切削速度快，加工精度高。接触成形可有效地提高加工效率。曲面接触加工的研究已经深入。

Line contact machining refers to the process of line contact in the machining process, such as cylindrical milling, conical milling, camshaft drilling, belt grinding, etc. It is characterized by high cutting speed and high machining accuracy. Contact forming can effectively improve the machining efficiency. The research of surface contact machining has been in-depth.

五轴雕刻机的优点是工件易于夹紧。不需专用夹具的加工，降低夹具成本，避免大量的夹具，提高模具加工精度。采用五轴加工模具可减少夹具的使用量。此外，由于五轴机床在加工过程中可以节约大量的专用工具，因此可以降低刀具成本。采用五轴数控加工技术，可提高有效刀刃长度，减少切削力，提高刀刃寿命，降低成本。

The advantage of five axis engraving machine is that the workpiece is easy to clamp. No special fixture processing, reduce the cost of fixture, avoid a large number of fixtures, improve the accuracy of mold processing. Using five axis machining die can reduce the use of fixture. In addition, because the five axis machine tool can save a lot of special tools in the processing process, it can reduce the cost of cutting tools. The five axis NC machining technology can improve the effective blade length, reduce the cutting force, improve the blade life and reduce the cost.

采用五轴机床加工模具，可以快速完成模具加工，快速交货，更好地保证了模具加工质量，使模具加工更加简单，模具修改更加方便。常规模具加工中，一般采用立式加工完成对工件的铣削加工。伴随着模具制造技术的不断发展，立式加工自身的缺陷也日益突出。

Using five axis machine tool to process the mold can quickly complete the mold processing, fast delivery, better ensure the quality of mold processing, make the mold processing more simple, mold modification more convenient. In the conventional mold processing, the vertical machining center is generally used to complete the milling of the workpiece. With the continuous development of mold manufacturing technology, the defects of vertical machining center are becoming increasingly prominent.

现代化的模具加工一般采用球头铣刀，球头铣刀在模具加工中的优点是显而易见的，但如果采用立式加工，那么底线的流速为零，因此完成的底部很差，如果采用四轴和五轴加工模具，则可克服上述缺点。

Modern mold processing generally uses ball end milling cutter. The advantages of ball end milling cutter in mold processing are obvious. However, if vertical machining center is adopted, the flow rate of bottom line is zero, so the finished bottom is very poor. If four axis and five axis mold are used, the above disadvantages can be overcome.
