一、概述近年来,随着电火花加工工艺的不断推广应用,以及对线切割工艺研究的进一步深入,电极丝的振动及其对加工工艺的影响已逐渐引起人们的重视,而研究电极丝振动的前提便是要测试其振动。常用的电极丝,为一直径仅0.2mm左右且以约7～10米/秒的速度沿轴向作高速运动的柔顺细弦。由于这两大特征,即1.丝为柔顺的几乎无刚性的钼丝,2.它在作高速运动,因而给其振动的测试带来了许多困难。我们分析了国内外有关振动测试的数种方案:设计了该测试装置,并进而将其完善为一台可 First, an overview In recent years, with the EDM continue to promote the use of wire cutting technology and further research, the wire electrode vibration and its impact on the processing technology has gradually attracted people’s attention, while studying the wire vibration The premise is to test its vibration. Commonly used wire electrode, is a diameter of only about 0.2mm and about 7 to 10 m / s speed along the axis for high-speed movement of the soft string. Because of these two major characteristics, namely 1. The silk is a compliant, almost rigid, molybdenum wire, 2. It is moving at high speeds and therefore presents a number of difficulties in the testing of its vibrations. We analyzed several domestic and international vibration test program: the design of the test device, and then improve it as a can
