This report deals with a newly developed Numerical Contouring Control Electric Discharge Machining(NCC-EDM) system which is based on Profile Electrode. Controuring NC data and 6-axis NC discharge machine. The proposed NCC-EDM makes it possible to efficiently generate 3-dimensional curved surfaces, configurated by the combination of cross section profiles and its axial motion. In order to generate NC data for the profile electrode and axial motion from given drawings, an Automatic Programming System(APSET-2) has been developed. NCC-EDM system has the following characteristics:1) As the stock removal is performed as terpanning by using the profile electrode, high speed and low energy machining process is possible.2) Regarding the machining od 3-dimensional swept surfaces which consist of cross sectional profile and axial motion, the shape of electrode is easily machined by using NC wire discharge machine, and the data of axial motion is also easily produced by the developed Automatic Programming System (APSET-2).3) The proposed NCC-EDM permits us to produce a complex 3-dimesional mold cavity without any complex female electrode. And a number of such complex 3-dimesional shapes can be made and tries out in a very short time with APSET-2.4) High accuracy of the electrode shape can be obtained by standardizing of the electrodes. Furthermore, higher machining accuracy and resistance against the electrode wear, can be obtained by using an Automatic Tool Changer(ATC).

本文介绍了一种新型的基于轮廓电极的数控电火花加工系统。控制数控数据和六轴数控放料机。提出的nc - edm可以有效地生成三维曲面，由截面轮廓及其轴向运动组合而成。为了从给定的图纸中生成轮廓电极和轴向运动的数控数据，开发了一个自动编程系统（APSET-2）。NCC-EDM系统具有以下特点：1)由于用型材电极将坯料以刨削的方式进行，因此可以实现高速低能的加工过程。2)对于由横截面轮廓和轴向运动组成的三维扫描曲面的加工，采用数控线切割机床可以方便地加工出电极的形状，并且利用开发的自动编程系统（APSET-2）也可以方便地生成轴向运动的数据。3)提出的nc - edm允许我们在没有任何复杂的母电极的情况下生产复杂的三维模具腔。使用APSET-2.4可以在很短的时间内制作出大量这样复杂的三维形状并进行试验。)通过电极的标准化，可以获得较高的电极形状精度。此外，使用自动换刀器（ATC）可以获得更高的加工精度和抗电极磨损的能力。
