三次元量測儀原理

v空間物體是由三度空間的座標尺寸所構成，即長、寬、高三種長度尺寸。因此若有一測量儀器能同時測量三度空間的尺寸，即空間座標值，此種測量儀器稱為三次元座標量測儀。

Space object is constituted by three-dimensional coordinates of the size of that length, width and height dimensions of three lengths. Therefore, if a three-dimensional measuring instrument can simultaneously measure the size of that space coordinate values, such measuring instruments called three dimensional coordinate measuring instrument.

v三次元量測儀可定義為“一種具有可作三個方向利用手動或控制器控制馬達驅動移動的探測器，可在三個相互垂直的導軌上移動，此探測器以接觸或非接觸等方式傳送訊號，三個軸之位移量測系統 ( 如光學尺 ) 經數據處理器或電腦等計算出工件的各點座標 (x,y,z) 及各項功能量測的儀器”。

3D measurement instrument can be defined as "having three directions can be used manually or use a motor drive controller controls movement detector can be moved in the three mutually perpendicular rails, this probe to the contact or non-contact, etc. send signals, the three axes of the displacement measurement system (such as a linear scale) through a data processor or computer to calculate the workpiece coordinate points (x, y, z) and the functions of the measuring instrument. "

v其量測原理是利用測針(一般為紅寶石的測針)去碰撞工件的邊緣，取得該位置的座標值，再減去該探頭的半徑即為工件的真實座標值。一般而言，量測軟體會自動做轉換動作，便可計算出所要的座標值或尺寸。

Its measurement principle is to use the stylus (usually ruby stylus) to the edge of the workpiece collision, get the coordinates of the value of the position, minus the radius of the probe is the real coordinate values of the workpiece. In general, the measurement software will automatically do the conversion action, you can calculate the desired coordinate value or size.

v三次元座標量測儀機台結構大部份為精密花崗石平台，台面上有固定工件鎖孔，因為花崗石具有不變形、硬度高、耐磨性強等優點。三軸大部份亦使用花崗石，有些使用鋁合金或鑄鐵，較高階的機種會使用碳纖、陶瓷或其它複合材質,相對的成本也比較高。

Three yuan coordinate measuring instrument machine structure for the most sophisticated granite platform, a fixed workpiece table lock, because granite with no deformation, high hardness, wear resistance and other advantages. Most also use triaxial granite, some use aluminum or cast iron, the higher-order models will use carbon fiber, ceramic or other composite materials, the relative cost is relatively high.

v三次元座標量測儀形式，依主軸支撐方式可分為懸臂型與橋架型。常見的外型結構為龍門式(或稱移動橋架式)，其他較常見的有單邊架橋式(或稱L橋架式)、雙邊架橋式、懸臂式等。

Three yuan coordinate measuring instrument form, according to the spindle support can be divided into type and cantilever bridge type. Common exterior structure gantry (or moving bridge type), there are other more common unilateral bridging formula (also known as L-type bridge), bilateral bridge, cantilevered and so on.

 v三次元量測儀依操作方式分類有手動和自動型式。

 1.  手動式三次元量測儀:價格較便宜,但用手動量測會有餘旋誤差產生,適合簡單的幾何公差量測

 2.  CNC式三次元量測儀:價格較昂貴,可自動產生法線方向路徑量測,教導式程式編輯可讓你首件量測完成即可當成程式使用,適合大量或有曲面的產品量測

 Coordinate Measuring Machine classification by mode of operation manual and automatic types.

  1. Manual Coordinate Measuring Machine: cheaper, but will hand more than a spin momentum measurement error generation, suitable for simple geometric tolerance measurement

  2. CNC type 3D measurement instrument: more expensive, can automatically generate the normal direction of the measurement path, didactic program that lets you edit the first pieces of measurement can be completed as program use, suitable for a large amount of product or curved surface measure

v運動方式一般區分為滾珠線性滑軌及氣浮滑軌兩種，滾珠線性滑軌的干涉及變形較大，比較少使用在大型機台；現今的主流為氣浮滑軌，其原理為壓縮空氣在空氣軸承與軌道間形成一個幾微米 (μm) 低摩擦力及低阻力的空氣層，也就是說空氣軸承會浮在軌道上，這時便可輕易移動。 

Ball movement is generally divided into two kinds of linear slide rails and flotation, ball linear slide interference and large deformation, less use of the mainframe platform; today's mainstream slide as flotation, the principle of compressed air between the bearing and the track is formed a few microns (μm) low friction and low air resistance layer, that will float on the air bearing track, then you can easily move.

v三次元量測儀之量測功能受儀器結構影響外，測頭系統也是極為重要之因素之一。

Three measurement functions yuan measurement instrument of influence by the instrument structure, the probe system is also a factor of great importance.

v因應不同應用，測針分很多種類型測針，一般分為紅寶石探針與硬式探針(掃描碰觸用)。

In response to different applications, for very many types of stylus stylus, generally divided into ruby probe and Hard probe (scanning touch with).

v三次元量測儀測頭一般組成為測座+測頭+測針

3D measurement instrument probe is generally composed of measuring head stylus + probe +Styli
