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 and mechanical equipment, with the help of machinery, our workload, effect, speed is much faster. Although there are mechanical equipment to help, but the face of the customer on the quality of the product requirements are so high. Nature in the process of high accuracy requirements, such as precision machinery parts processing. When machining parts for precision machines, digital programmed contour systems are widely used on milling machines, including phase systems with a wide range of technological capabilities, which are simple, reliable and inexpensive, in particular, used to control the large-scale three-dimensional surface of precision machinery parts processing. One of the main conditions to ensure the machining quality of precision machine parts is to compile control program correctly. For the Digital Program Control Phase System, the preparation of the control program is carried out by the automatic program preparation system, the quality level of which largely depends on the price of the preparation control program. The other is the processing error caused by the manual control equipment, which includes the accidental error and the systematic error of the process system. The system error plays a major role in the total machining error, and it will cause a series of NC process system error for the whole machining of precision machine parts. For example, the clearance, which is the same as the insensitive belt in the transmission chain of the machine tool, but does not include the clearance of the reverse transmission chain; the amplification factor of the unstable transmission; the phase error in the control tape;. The periodic step instability of sensor feedback is mainly in the form of phase instability.
