本文首先指出进行刀具耐用度试验研究的重要意义。回顾了过去常用的几种快速试验法。分别对常规试验法、阶梯试验法、五点试验法、端面车削试验法、圆锥车削试验法等刀具耐用度试验作了介绍,以钛合金车削为例,给出T—v公式的计算结果,经验证明,这几种快速试验法,特别是当它们结合生产进行时,对于刀具耐用度的预测和控制是很有帮助的。 This paper first points out the importance of tool durability test. Review several commonly used rapid test method. The durability tests of the tools such as the conventional test method, the ladder test method, the five-point test method, the end face turning test method and the conical turning test method are respectively introduced. Taking the titanium alloy turning as an example, the calculation result of the T-v formula is given, Experience has shown that these rapid test methods, especially when they are combined with production, are useful for predicting and controlling tool durability.
