前言在精密切削加工中,一旦刀具发生磨损,无论机床的运动精度多高,也难保证制品的精度。为此,操作者必须时刻监视切削加工状态,不断测试工件尺寸精度。一旦发现刀具磨损和折损等异常现象时,就立即停机,更换刀具或调整刀尖位置。这样不世保证了工件质量,而且保护了机械设备和刀具。然而,在高度自动化的精密数控机床上进行人工监视,却是非常困难的。特别是在多机床管理或无人管理的情况下,必须采用特殊手段对切削状态进行自
Preface In precision cutting, once the tool wear, no matter how high the accuracy of machine tool, it is difficult to ensure the accuracy of products. To this end, the operator must always monitor the state of machining, continuous testing of workpiece size accuracy. Once the tool is found to wear and tear and other anomalies, immediately shut down, change the tool or adjust the tip position. This worldly guarantee the quality of the workpiece, but also protect the machinery and equipment and tools. However, manual monitoring on a highly automated, precision CNC machine is very difficult. Especially in the case of multi-machine management or unmanned, special measures must be taken to cut the state from
