机械加工的精准度跟哪些因素有关呢?
厂家的生产跟机械设备有关系,有了机械的帮助,我们的工作量,效果,速度上都快很多。虽然说有机械设备的帮助,但是面对客户对产品的质量要求那么高。自然在加工过程的精准度要求高,比如说精密机械零部件加工。
精密机械零部件加工的时候,在铣床上广泛采用数字程序控制的轮廓系统,其中包括具有广泛的工艺能力,简单可靠且价格低廉的相位系统,这些系统被很多工厂采用,特别是用来控制大型立体型面的精密机械零件加工。
正确编制控制程序是保证精密机械零部件加工质量的主要条件之一。对数字程序控制相位系统而言,控制程序的准备工作由采用自动程序准备系统来进行,其质量水平在很大程度上取决于准备控制程序的价格。
其它是人工控制设备时产生的加工误差,这些误差包括工艺系统的偶然误差和系统误差。全部加工误差中系统误差起主要作用,对精密机械零部件加工整体而言,会引起一系列数控工艺系统误差。
比如说间隙,其后果如同机床传动链中的不灵敏带,但不包括反向传动链间隙;不稳定传动的放大系数;在控制程序磁带上的相位误差;.传感器反馈的周期性步进不稳定性,其主要形式是相位形式不稳定。
What factors are involved in machining accuracy?
The production of manufacturers is related to mechanical equipment. With the help of machinery, our workload, effect and speed are much faster. Although said to have the help of mechanical equipment, but in the face of the customer's product quality requirements are so high. Nature requires high precision in the processing process, such as precision mechanical parts processing.
Precision machine parts processing, in milling machine widely used digital program control contour systems, including a wide range of process capabilities, simple and reliable and inexpensive phase systems, these systems are used by many factories, especially for the control of large vertical surface precision machine parts processing.
Correct programming of control program is one of the main conditions to ensure the machining quality of precision machinery parts. For digital program-controlled phase system, the preparation of control program is carried out by the use of automatic program-controlled preparation system, and its quality level depends largely on the price of the preparation control program.
The other is the machining error caused by manual control of the equipment, including the accidental error and systematic error of the process system. System error plays an important role in all the machining errors, which will cause a series of NC process system errors for precision machine parts machining as a whole.
For example, clearance, its consequences as the machine tool transmission chain in the insensitive belt, but does not include the reverse transmission chain clearance; Amplification factor of unstable drive; Phase error on control program tape; The main form of periodic step instability of sensor feedback is phase instability.
