微型雕刻機總體及數(shù)控系統(tǒng)選用設(shè)計
摘要： 隨著微電子技術(shù)和微型計算機的飛速發(fā)展，微型雕刻機的應(yīng)用越來越廣泛。機電一體化廣泛地綜合了機械、微電子、自動控制、信息、傳感測試、電力電子、接口、信號變換和軟件編程等技術(shù)，并將這些技術(shù)有機的結(jié)合成一體，它是當(dāng)今世界機械工業(yè)技術(shù)和產(chǎn)品發(fā)展的主要趨勢。
本文調(diào)查研究了雕刻機的發(fā)展，介紹臺式數(shù)控龍門雕刻機X的設(shè)計過程，包括機床總體方案設(shè)計、主傳動系統(tǒng)設(shè)計和X向進(jìn)給傳動系統(tǒng)的機械結(jié)構(gòu)設(shè)計。X向進(jìn)給傳動系統(tǒng)中主要分析了絲杠的安裝，以及相關(guān)固定和支承。計算主要有兩個方面：對滾珠絲杠和X軸電機的選擇計算和校核。此外，我還進(jìn)行了數(shù)控系統(tǒng)的選擇，數(shù)控系統(tǒng)是機床自動化的重要組成部分,其性能直接影響到加工的精度、效率及生產(chǎn)企業(yè)的效益。本文詳細(xì)介紹了數(shù)控系統(tǒng)及驅(qū)動單元的原理及其優(yōu)缺點,如何選擇性價比最好、最合適的數(shù)控系統(tǒng)及驅(qū)動單元。
本課題是在參考現(xiàn)有雕刻機的基礎(chǔ)上，設(shè)計一種機構(gòu)尺寸比較簡單的數(shù)控雕刻機，適用性比較大的工藝品的雕刻加工。

Miniature engraving machine overall and selection design of CNC system
Abstract：Along with the development of micro-electronics technology and microcomputer technology，miniature engraving machine will be widely used. These technologies are widely used in Mechatronics, including mechanism, microelectronics，autocontrol, information, sensor and test,power and electron, interface, signal transform, software program. On the other hand, mechatronics maked these technologies integrated closely. It is the primary trend of the development of mechanical industrial technology and products in the world nowadays.
The development of the CNC engraving machine and the meaning of the electric spindle to the NC machine was investigated about this thesis. The process of design for the X axle in Desk-work CNC engraving and milling machine was introduced, including the design project of the machine, the design of the mechanical structures of the feeding mechanism of X axis. In the section of the feeding machine of X axis , the assembly of the straight guide-way and the bearing of the ball screw and so forth was presented .The calculation mainly includes two aspects: choosing and verifying the servo-motor of X axis. At last,In addition, I also had the choice of numerical control system CNC system is an important component of machine tool automation,and the capacity directly affected the machining accuracy,efficiency and the benefit of the production enterprise.The principle and advantage/disadvantage of CNC system and driver unit were introduced.How to select the highest price ratio and most appropriate CNC system and driver unit was also described.
This topic is based on the existing engraving machine to design a CNC engraving machines with a simple size, which adapted to the relatively large carving handicraft processing.
Keywords: Engraving plotter, numerical control system, mechatronics, X axis，and interpolation arithmetic.
