机械加工的精准度跟哪些因素有关呢?
 
What factors are related to the accuracy of machining?
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。
The manufacturer's production is related to mechanical equipment. With the help of machinery, our workload, effect and speed are much faster. Although there are mechanical equipment to help, but in the face of customer requirements for product quality so high. Naturally, the accuracy of the processing process is required to be high, such as precision machining of parts.
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。
During the processing of precision machine parts, the contour system controlled by digital program is widely used in milling machine, including the phase system with extensive process capability, simple and reliable, and low price. These systems are adopted by many factories, especially for controlling the processing of large-scale solid surface precision machine parts.
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。
It is one of the main conditions to ensure the machining quality of precision machine parts to make the control program correctly. For the digital program control phase system, the preparation of the control program is carried out by using the automatic program preparation system, and its quality level largely depends on the price of the preparation control program.
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。
The others are the processing errors caused by the manual control of the equipment. These errors include the accidental errors and system errors of the process system. System error plays an important role in all machining errors. As a whole, it will cause a series of CNC process system errors.
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。
For example, clearance has the same consequences as the insensitive belt in the machine tool drive chain, but does not include the reverse drive chain clearance; the amplification factor of unstable drive; the phase error on the control program tape; the periodic step instability of sensor feedback, the main form of which is the instability of the phase form.
