The machine center uses a commercially available PC-Based CNC controller and micro-EDM power supply. The structure design is based on an open L-shaped granite base, where a Z-axis platform is mounted on the top of an L-type base, while X and Y-axis platforms are assembled by stacking. Additionally, a fuel tank, WEDG winding mechanism and a work piece holder were fixed to the X-axis work platform. Three-axis positioning stages use servomotors to drive lead screws for motion control. Equipped with a commercially available PC-Based CNC controller, any processing path and precision motion control can be achieved. In addition, the Z-axis platform includes a commercially available rapid adapter for the rapid assembly of C-axis rotation, high-speed micro-milling spindle and three-dimensional measuring probe. This means that the machine can quickly switch between micro-EDM, high-speed micro-milling and three-dimensional measurement. The machine center successfully produced micro probes with a front-end sphere with a diameter of less than 100 μm. Combined with a self-developed trigger circuit, it also completed a three-dimensional touch trigger probe. The measurement software was developed with Borland C++ Builder. Integrating the three-dimensional touch trigger probe with the three-axis linear scale, the three-dimensional coordinates of the measured values were calculated and processed. It has been successfully applied to the measurement of point, line, circle and angle. 本研究旨在開發(fā)一個加工中心組成的高速微型銑床，微細電火花加工、三坐標測量機。加工中心采用CNC控制器和微細電火花加工電源的商用PC。結構設計是基于一個開放的L形的花崗巖基座，在Z軸平臺安裝在L型底座的頂部，而X和Y軸平臺是由堆疊。此外，一個燃料箱，電極卷繞機構、工件夾持固定到軸工作平臺。三軸定位階段采用伺服電機驅動的絲杠運動控制。配備了一個數控控制器商用PC，任何加工路徑和精密運動控制可以實現(xiàn)。此外，Z軸平臺包括c軸旋轉快速組裝使用市售的快速接頭，高速微銑削主軸和三維測量探頭。這意味著，機器可以快速在微細電火花開關，高速微銑削和三維測量。加工中心的成功產生微探針與一個直徑小于100μM.結合自行研制的觸發(fā)電路前端的球體，它還完成了三維觸發(fā)式探頭。用Borland C++ Builder開發(fā)了測量軟件。三維觸發(fā)式測頭的三軸線性尺度積分，計算和處理的三維坐標的測量值。它已成功地應用于測量的點，線，圓，角 [2] Different types of geometric models of face-gear with circle line of teeth have been shown in the paper.

In aviation and mould and die industry, it is much significant to achieve high accuracy CNC machining on complex profile parts. The unsmooth Acceleration/Deceleration (ab. Acc/Dec) control in feed movement is one of the main reasons to bring about machine tools impact and vibration in practical machining. After analyzing the CNC machine tools dynamic model, an Acc/Dec control algorithm based on trapezoid-curve jerk is put forward in order to avoid step change in jerk curve in the study; Moreover, the motion profile smooth control approach based on continuous jerk is developed in details to decrease machine tools impact according to various kinematics constraint conditions, such as the maximum acceleration, the maximum jerk, the machining program segment displacement, the instruction feedrate and so on; Finally, the developed Acc/Dec approach and the traditional linear Acc/Dec approach are compared in the CNC experimental table. The results reveal that the developed approach can achieve more smooth and flexible motion profile, which is helpful to minish machine tools impact and enhance parts machining surface quality. 在這項研究中，我們提出了加速/減速基于數控加工梯形曲線沖擊控制算法。在航空和模具行業(yè)，是實現(xiàn)高精度數控系統(tǒng)在復雜型面零件的加工更重要。不平順的加速/減速（簡稱ACC / DEC）在進給運動控制是一個帶來實際加工機床的沖擊和振動的主要原因。在分析了數控機床的加減速動態(tài)模型，提出了以避免在研究反射曲線的階躍變化基于梯形曲線沖擊控制算法；此外，運動軌跡的平滑控制方法的基礎上連續(xù)反射是在細節(jié)降低機床的影響根據不同的運動學約束條件，如最大加速度，最大的混蛋，加工程序段位移，指令進給速度等；最后，開發(fā)的加速/減速的方法和傳統(tǒng)的線性加/減速的方法是在數控實驗臺的比較。結果表明，所提出的方法可以實現(xiàn)更光滑柔軟的運動軌跡，有助于減小機床的影響，提高零件的加工表面質量。 [8] A compound process that integrates end electrical discharge (ED) milling and mechanical grinding to machine silicon carbide (SiC) ceramics is developed in this paper. The process employs a turntable with several uniformly-distributed cylindrical copper electrodes and abrasive sticks as the tool, and uses a water-based emulsion as the machining fluid. End electrical discharge milling and mechanical grinding happen alternately and are mutually beneficial, so the process is able to effectively machine a large surface area on SiC ceramic with a good surface quality. The machining principle and characteristics of the technique are introduced. The effects of polarity, pulse duration, pulse interval, open-circuit voltage, discharge current, diamond grit size, emulsion concentration, emulsion flux, milling depth and tool stick number on performance parameters such as the material removal rate, tool wear ratio, and surface roughness have been investigated. In addition, the microstructure of the machined surface under different machining conditions is examined with a scanning electron microscope and an energy dispersive spectrometer. The SiC ceramic was mainly removed by end ED milling during the initial rough machining mode, whereas it is mainly removed by mechanical grinding during the later finer machining mode; moreover, the tool material can transfer to the workpiece surface during the compound process. 將端電火花復合工藝（ED）銑削與機械磨削加工碳化硅（SiC）陶瓷進行。該方法使用一個轉盤與幾個均勻分布的圓柱形銅電極和研磨棒為工具，采用水基乳液作為加工液。端電火花銑削與機械磨削交替出現(xiàn)的現(xiàn)象，是互惠互利的，所以這個過程是能夠有效地機大面積的SiC陶瓷具有良好的表面質量。介紹了加工技術的原理和特點。極性，脈沖持續(xù)時間，脈沖間隔的影響，開路電壓，放電電流，金剛石磨粒的大小，乳化液的濃度，乳化液流量，銑削深度和工具桿數對性能參數如材料去除率，刀具的磨損率，和表面粗糙度進行了研究。此外，不同的加工條件下加工表面微觀結構用掃描電子顯微鏡和能量色散譜儀研究。SiC陶瓷的電火花銑削初始粗加工模式中的主要去除，而這主要是去除機械研磨后精細加工模式期間；此外，刀具材料可以轉移到工件表面的復合過程。 [9] Purpose: The work presented in this paper might be used for basic data in the design of a lot extruded aluminum products using the variable section extrusion process.Design/methodology/approach: The capacity of a CNC extruder was calculated and decided as analyzing the FEM results performed by commercial software DEFORM-2D.
