(1) The inspection design hand board is not only visible, but also touchable. It can intuitively reflect the designer's creativity in the form of physical objects, avoiding the disadvantage of "drawing is good-looking but making is not good-looking". Therefore, hand board production is essential in the process of new product development and product shape deliberation.

（2）檢驗(yàn)結(jié)構(gòu)設(shè)計(jì)因?yàn)槭职迨强裳b配的，所以它可直觀的反映出結(jié)構(gòu)的合理與否，安裝的難易程度。便于及早發(fā)現(xiàn)問題，解決問題。

(2) Check the structural design. Because the hand board can be assembled, it can intuitively reflect the rationality of the structure and the difficulty of installation. It is convenient to find and solve problems as soon as possible.

（3）避免直接開模具的風(fēng)險(xiǎn)性由于模具制造的費(fèi)用一般很高，比較大的模具價(jià)值數(shù)十萬(wàn)乃幾百萬(wàn)，如果在開模具的過(guò)程中發(fā)現(xiàn)結(jié)構(gòu)不合理或其他問題，其損失可想而知。而手板制作則能避免這種損失，減少開模風(fēng)險(xiǎn)。

(3) Avoid the risk of directly opening the mold. Due to the high cost of mold manufacturing, the relatively large mold is worth hundreds of thousands or even millions. If the structure is unreasonable or other problems are found in the process of opening the mold, the loss can be imagined. The hand board production can avoid this loss and reduce the risk of mold opening.

（4）使產(chǎn)品面世時(shí)間大大提前由于手板制作的超前性，你可以在模具開發(fā)出來(lái)之前利用手板作產(chǎn)品的宣傳，甚前期的銷售、生產(chǎn)準(zhǔn)備工作，及早占領(lǐng)市場(chǎng)。

(4) The product launch time is greatly advanced. Due to the advance of hand board production, you can use hand board for product publicity before the mold is developed, and even preliminary sales and production preparations to occupy the market as soon as possible.

一）按制作手段分

1） By production method

手板按照制作的手段分，可分為手工手板和數(shù)控手板：

According to the manufacturing methods, the hand board can be divided into hand board and NC hand board:

（1）手工手板：其主要工作量是用手工完成的。

(1) Manual hand board: its main workload is completed by hand.

（2）數(shù)控手板：其主要工作量是用數(shù)控機(jī)床完成的，而根據(jù)所用設(shè)備的不同，又可分為激光快速成形(RP,RapidPrototyping)手板和加工（CNC）手板。

(2) CNC hand board: its main workload is completed by CNC machine tools. According to the different equipment used, it can be divided into laser rapid prototyping (RP) hand board and machining (CNC) hand board.

A：RP手板：主要是用激光快速成型技術(shù)生產(chǎn)出來(lái)的手板。

A: RP hand board: it is mainly produced by laser rapid prototyping technology.

：CNC手板：主要是用加工生產(chǎn)出來(lái)的手板。

: CNC hand board: it is mainly produced by processing.

手板同CNC手板相比較各有千秋：

Compared with CNC hand board, the hand board has its own advantages:

手板的優(yōu)點(diǎn)主要表現(xiàn)在它的快速性上，但是它主要是通過(guò)堆積技術(shù)成型，因而RP手板一般相對(duì)粗糙，而且對(duì)產(chǎn)品的壁厚有一定要求，比如說(shuō)壁厚太薄便不能生產(chǎn)。

The advantages of the hand board are mainly reflected in its rapidity, but it is mainly formed by stacking technology. Therefore, the RP hand board is generally relatively rough and has certain requirements for the wall thickness of the product. For example, if the wall thickness is too thin, it can not be produced.

CNC手板的優(yōu)點(diǎn)體現(xiàn)在它能非常的反映圖紙所表達(dá)信息，而且CNC手板表面質(zhì)量高，尤其在其完成表面噴涂和絲印后，甚比開模具后生產(chǎn)出來(lái)的產(chǎn)品還要光彩照人。因此，CNC手板制造愈來(lái)愈成為手板制造業(yè)的主流。

The advantage of CNC hand board is that it can very reflect the information expressed in the drawing, and the surface quality of CNC hand board is high, especially after its surface spraying and silk screen printing, it is even more glorious than the products produced after opening the mold. Therefore, CNC hand board manufacturing has increasingly become the mainstream of hand board manufacturing industry.
