四建立耐振性標準 切削時發生振動,有二个特征:卽噪音和表面振動痕跡。如果切削時既没有噪音發生,表面上又沒有振動痕跡(波高不超过30公微),則这样的工作条件应認为是無振的工作条件。相反地,如切削時有噪音和表面振動痕跡(波高大於30公微),則这样的工作条件应为有振的工作条件。介於二者之間的叫做过渡工作条件,看其特徵的顯著程度,而屬於有振的或無振的。从这样观點出發,可以建立一系列标準。根据这些标準便可確定在某些条件下是否为無振工作条件。完成工作的各种条件(切削用量、刀具、机床等等)都可能在或大或小的程度上發生振動。为了精确地評定这些性能,必須確定一些耐振性标準。
Fourth, the establishment of vibration resistance Standard vibration occurs during cutting, there are two characteristics: 卽 noise and surface vibration traces. If there is no noise during cutting and there is no vibration mark on the surface (the wave height does not exceed 30 micro-heights), then such working conditions shall be regarded as vibration-free working conditions. Conversely, if there is noise and surface vibration marks during cutting (the wave height is greater than 30 micro-hertz), then such operating conditions should be vibration operating conditions. Between the two is called transitional working conditions, to see the salient features of its characteristics, which are vibrating or vibrationless. From this point of view, we can establish a series of standards. Based on these criteria, it is possible to determine whether or not a condition of vibration-free operation exists under certain conditions. Various conditions (cutting amount, tools, machine tools, etc.) to complete the work may vibrate to a greater or lesser extent. In order to accurately evaluate these properties, some criteria for vibration resistance must be established.
