機械加工的精準(zhǔn)度跟哪些因素有關(guān)呢？
廠家的生產(chǎn)跟機械設(shè)備有關(guān)系，有了機械的幫助，我們的工作量，效果，速度上都快很多。雖然說有機械設(shè)備的幫助，但是面對客戶對產(chǎn)品的質(zhì)量要求那么高。自然在加工過程的精準(zhǔn)度要求高，比如說精密機械零部件加工。
精密機械零部件加工的時候，在銑床上廣泛采用數(shù)字程序控制的輪廓系統(tǒng)，其中包括具有廣泛的工藝能力，簡單可靠且價格低廉的相位系統(tǒng)，這些系統(tǒng)被很多工廠采用，特別是用來控制大型立體型面的精密機械零件加工。
正確編制控制程序是保證精密機械零部件加工質(zhì)量的主要條件之一。對數(shù)字程序控制相位系統(tǒng)而言，控制程序的準(zhǔn)備工作由采用自動程序準(zhǔn)備系統(tǒng)來進(jìn)行，其質(zhì)量水平在很大程度上取決于準(zhǔn)備控制程序的價格。
其它是人工控制設(shè)備時產(chǎn)生的加工誤差，這些誤差包括工藝系統(tǒng)的偶然誤差和系統(tǒng)誤差。全部加工誤差中系統(tǒng)誤差起主要作用，對精密機械零部件加工整體而言，會引起一系列數(shù)控工藝系統(tǒng)誤差。
比如說間隙，其后果如同機床傳動鏈中的不靈敏帶，但不包括反向傳動鏈間隙；不穩(wěn)定傳動的放大系數(shù)；在控制程序磁帶上的相位誤差；.傳感器反饋的周期性步進(jìn)不穩(wěn)定性，其主要形式是相位形式不穩(wěn)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.
