The production of the handboard model shall go through the cutting process, which can be divided into at least three types:

　　粗加工、半精加工、精加工，有時甚是超精加工(主要用于高速切削應(yīng)用)。殘馀銑削當(dāng)然是為半精加工后的精加工而準(zhǔn)備的。重要的是要為每個流程的下一步留出均勻分布的空白。如果在工具路徑和工作負載的方向上幾乎沒有快速的變化，那么工具的壽命可以得到延長，并且更加可預(yù)測。如有可能，應(yīng)在專用機床上進行精加工。這將在更少的調(diào)試和裝配時間內(nèi)提高手板模型的幾何精度和質(zhì)量。

　　Roughing, semi finishing, finishing, and sometimes even super finishing (mainly for high-speed cutting applications). Of course, residual milling is prepared for finishing after semi finishing. It is important to leave a evenly distributed gap for the next step in each process. If there is little rapid change in the direction of tool paths and workloads, tool life can be extended and more predictable. If possible, finish machining shall be carried out on special machine tools. This will improve the geometric accuracy and quality of the handboard model in less debugging and assembly time.

　　切削過程中更重要的目標(biāo)之一是在每個加工過程中為每個刀具創(chuàng)建一個均勻分布的加工余量。這意味著必須使用不同的直徑(從大到小)，特別是在粗糙和半成品過程中。在任何時候，主要的標(biāo)準(zhǔn)應(yīng)該是在每個過程中盡可能接近更終的手板模型的形狀。

　　One of the most important goals in the cutting process is to create a uniformly distributed machining allowance for each tool in each machining process. This means that different diameters (from large to small) have to be used, especially in rough and semi-finished processes. At any time, the main criterion should be to be as close to the shape of the final prototype as possible in each process.

　　手板模型為每個刀具提供了均勻分布的加工余量，以確保恒定和高生產(chǎn)率和的切削過程。當(dāng)ap/ae(軸向切削深度/徑向切削深度)不變時，切削速度和進給速度也可以保持在較高的水平。這樣，切削刃上的機械作用和工作量變化不大，使得手板模型產(chǎn)生的熱量和疲勞更少，從而提高了刀具壽命。如果以下工序為部分半精加工工序，特別是全部精加工工序，則可進行無人加工或部分無人加工。手板模型材料的恒加工余量也是高速切削應(yīng)用的基本標(biāo)準(zhǔn)。

　　The handboard model provides a uniform distribution of machining allowance for each tool to ensure a constant, high productivity and safe cutting process. When AP / AE (axial cutting depth / radial cutting depth) is constant, the cutting speed and feed speed can also be kept at a high level. In this way, the mechanical function and workload of the cutting edge change little, which makes the heat and fatigue produced by the hand plate model less, thus improving the tool life. If the following processes are partial semi finishing processes, especially all finishing processes, unmanned processing or partial unmanned processing can be carried out. The constant machining allowance of handboard model material is also the basic standard of high-speed cutting application.
