From the view of economy and practice this paper introduces a renewal design of measure - control system for old model electric spark machine tools , which are widely used in many enterprises in east zhejing at present 从经济性和实用性出发，对日前浙东地区中小企业较多使用的一些中低档电火花加工机床的测控系统进行了更新设计。
Abstract : the precision of electric spark machine - shaping is directly related with amount of electrode loss . according to the main factors of effecting on electrode loss , the countermeasures are suggested for decreasing and controlling electrode loss 文摘:电火花成型加工的精度，与电极的损耗程度有直接的关系.针对影响电极损的主要因素，提出了减少和控制电极损耗的相应对策
Locates in winner way industrial park , south district of the dong guan city , guang dong province . our company specializes in the exploiting , manufacturing and distributing of cnc electric spark wire cutting machines and cnc electric discharge machine ,位于广东省东莞市南城区宏远工业区，是一家专门从事数控电火花线切割机床，数控电火花成型机床的开发、生产和销售的专业化公司。
On the basis of a lot of experimental data based on the orthogonal test of pulse peak electric current , pulse width and pulse intermission , experimental mathematical models of electric spark forming of several sorts of materials are built up with multiple linear regression analysis 摘要用正交试验法对电火花加工中的峰值电流、脉冲宽度、脉冲间隔进行设计，在大量实验数据的基础上，采用最小二乘法建立实用的多种材料的电火花加工实验数学模型。
Above all , the paper offers the detailed introduction for the hardware system of mould industry and electric spark machining . this article sets forth the thought requirement , the principle of recording , the thought of realizing , the puzzles in designing and the process of adjustment during collecting course , conversion system between light and electron in the track system of optics 为此，本文对模具工业生产及数控电火花线切割机的硬件系统做了详细的介绍，重点阐述了光学跟踪系统中光电转换系统的设计及数据采集、处理软件的整体要求，记录原理，实现思路，设计过程，以及调试误差分析。
Incondition of surface anti - corrision and insulation coat of metal and tiny hole of steel where resistance and crack is very small , when supplying a high voltage , gas crack will be punctured and electric spark discharging will occur , now send a pulse signal to the alarming circuit the alarmer can send out sound and light to alarm . we can do leak hunting on the coating according to this principle 金属表面绝缘防腐层过薄、漏铁及漏电微孔处的电阻值和气隙密度都很小，当有高压经过时就形成气隙击穿而产生火花放电，给报警电路产生一个脉冲信号，报警器发出声光报警，根据这一原理达到防腐层检漏目的。
Equipped with numerical control press , numerically controlled lathe , electric spark machine , line cutterbar , milling machine , line cutterbar , milling machine , facing machine , boring mill , drilling machine , injection machine , injection machine , automatic spring machines etc . , ziqiang is capable of cad , making mould as well as large - scale machining 公司具有极强大的机件加工能力，模具制造，应用计算机辅助设计（ cad ） ，机床有数控冲庆数控车床电火花线切割铣刨镗钻大小吨位冲床及注塑机床等。
This factory has advanced mould and blame bid at present manufacturing facilities : lathe of grinder of electric spark of cut of accurate numerical control line , numerical control , numerical control , numerical control , milling machine , punching machine , measuring projector and number stage doubleclick cold dui machine , 3 labour , 4 labour , 5 labour digit accuses to wait for cold dui equipment , assembled advanced cad / three - dimensional wait for computational subdesign to be able to come according to the client development tastes tulaiyang newly 本厂目前具有先进的模具及非标件生产设备：精密的数控线切割、数控电火花、数控磨床、数控车床、铣床、冲床、投影仪和数台双击冷镦机、三工位、四工位、五工位数控等冷镦设备，并装配了先进的cad /三维等计算辅助设计可根据客户来图来样开发新品。
From the above it will be realised that fundamental difference between petrol and diesel engines is that in the petrol engine the source of heat for igniting the charge , namely an electric spark , is generated outside the engine , and is taken , as it were , into the waiting charge at the required instant 翻译：在高速柴油机发展的早期，可变的正时装置被引用到油泵驱动联轴节上，采用螺旋式花键套管的形状，驱动轴和从动轴之间的相对角度可以通过手动或自动控制进行改变。
