The hand board model plays a key role in the R & D stage of the enterprise. It can detect the defects of the product appearance and structure. Most enterprises will find the hand board factory to verify the hand board after the completion of the drawing design. 3D drawing is an essential link for the production of the hand board model.

　　3D圖也叫三維立體圖，它能夠通過眼睛的視覺成像系統(tǒng)的重合和分離，讓觀者能夠地清楚其設計結構，對圖中隱含的圖像一目了然。

　　3D image is also called three-dimensional image. It can make the design structure clear and the hidden image clear through the superposition and separation of the visual imaging system of the eyes.

　　而手板制作企業(yè)則可以通過3D圖更加清楚、了解客戶所做手板模型的尺寸大小，內(nèi)部結構復雜度與產(chǎn)品外觀效果，判斷一個手板模型生產(chǎn)所需要的時間，能夠準確、快捷地給客戶報價和交期。

　　However, the handboard manufacturer can know the size, internal structure complexity and product appearance of the handboard model made by the customer more clearly through the 3D diagram, judge the time required for the production of a handboard model, and accurately and quickly quote and deliver the price to the customer.

　　同時不管是CNC加工還是SLA激光快速成型或者是3D打印加工都需要3D圖來進行編程的，然后根據(jù)設計產(chǎn)品的功能選擇相應的材料。

　　At the same time, no matter CNC processing, SLA laser rapid prototyping or 3D printing processing, 3D graphics are needed for programming, and then the corresponding materials are selected according to the functions of the designed products.

　　在手板制造行業(yè)中，不管是CNC加工、3D打印還是硅膠復模的加工方式，都需要客戶提供3D圖才可以制作，手板廠一般能打開3D圖紙格式有STP、IGS、PRT等，有些圖紙的格式是無法打開的，所以在交付工廠制作手板前，需要先詢問合適的3D圖紙格式。

　　In the handboard manufacturing industry, whether it is CNC processing, 3D printing or silicon replica processing, the customer is required to provide 3D drawings before production. Generally, the handboard factory can open 3D drawing formats, such as STP, IGS, PRT, etc., and some drawing formats cannot be opened. Therefore, before delivering the handboard to the factory for production, it is necessary to inquire the appropriate 3D drawing format.

　　就目前而言，制作手板主要方式主要有CNC加工、3D打印、真空復模、模具注塑等工藝。雖然這些制作技術的工作原理各不相同，但是，毋庸置疑的是都必須要用到3D圖紙。

　　At present, the main ways of making handboards are CNC processing, 3D printing, vacuum re molding, mold injection molding and other processes. Although the working principles of these manufacturing technologies are different, there is no doubt that 3D drawings must be used.

　　CNC加工的基本原理就是數(shù)控車床給加工路線指車刀從對刀點或機床固定原點開始運動起，直返回該點并結束加工程序所經(jīng)過的路徑，包括切削加工的路徑及刀具切入、切出等非切削空行程路徑，而這些路徑的設定都需要根據(jù)3D圖紙來設定的。

　　The basic principle of CNC machining is that the machining path given by CNC lathe refers to the path through which the turning tool moves from the tool setting point or the fixed origin of the machine until it returns to the point and ends the machining program, including the path of machining and the path of non cutting empty stroke such as cutting tool cut in and cut out, and the settings of these paths need to be set according to 3D drawings.

　　3D打印是一種數(shù)字模型文件為基礎，運用特殊蠟材、粉末狀金屬或塑料等可粘合材料，通過打印一層層的粘合材料來制造三維的物體。

　　3D printing is a kind of digital model file based on which three-dimensional objects are made by printing layers of adhesive materials, such as special wax, powder metal or plastic.

　　現(xiàn)階段3D打印機被用來制造產(chǎn)品。逐層打印的方式來構造物體的技術。3D打印機的原理是把數(shù)據(jù)和原料放進3D打印機中，機器會按照程序把產(chǎn)品一層層造出來。

　　At this stage, 3D printers are used to make products. The technique of building objects by printing them layer by layer. The principle of 3D printer is to put data and raw materials into 3D printer, and the machine will build products layer by layer according to the program.

　　真空復模技術是利用產(chǎn)品原型,如：快速原型件、樣件、手板在真空狀態(tài)下制作出硅膠模具，并在真空狀態(tài)下采用PU材料進行澆注，從而克隆出與產(chǎn)品原型相同的復制件。而這個復模手板的原型就是通過CNC加工或者3D打印做出來的，所以做復模手板也需要3D圖紙。

　　The vacuum replica technology is to use the product prototype, such as rapid prototype, sample and hand plate to make silica gel mold in vacuum state, and use PU material to pour in vacuum state, so as to clone the same replica as the product prototype. The prototype of the hand board is made by CNC processing or 3D printing, so 3D drawings are also needed to make the hand board.

　　如果沒有3D圖怎么辦？遇到這種情況的話，如果有產(chǎn)品實物也是可以做手板的，只需要將實物拿去抄數(shù)來畫3D圖就可以，或者尋找有設計能力的手板制作公司幫助設計圖紙。

　　What if there is no 3D map? In this case, if there is a real product, it can also be made of handboards. You only need to copy the real product to draw 3D drawings, or find a handboard making company with design ability to help design drawings.
