機(ji)械(xie)加工的精準度跟哪些因素有關呢？
廠家(jia)的(de)生產跟(gen)機(ji)(ji)械設備有(you)關系(xi)，有(you)了機(ji)(ji)械的(de)幫助，我們的(de)工作量，效果(guo)，速度(du)上都快很多。雖(sui)然說(shuo)有(you)機(ji)(ji)械設備的(de)幫助，但是面對客戶對產品的(de)質量要求(qiu)那(nei)么高。自然在加(jia)工過程的(de)精準度(du)要求(qiu)高，比如說(shuo)精密機(ji)(ji)械零部件(jian)加(jia)工。
精密機械零部件(jian)加(jia)工(gong)的(de)(de)時候，在銑床(chuang)上廣泛采用數字程序(xu)控制(zhi)的(de)(de)輪(lun)廓系(xi)統，其中包括具有廣泛的(de)(de)工(gong)藝能力，簡單可靠且價格低廉的(de)(de)相位系(xi)統，這些系(xi)統被很多(duo)工(gong)廠采用，特別是用來控制(zhi)大型立體(ti)型面的(de)(de)精密機械零件(jian)加(jia)工(gong)。
正確編(bian)制控制程(cheng)(cheng)序是保證精密機械(xie)零部件加工質(zhi)量的(de)主(zhu)要條件之一。對數字程(cheng)(cheng)序控制相位系(xi)統而言(yan)，控制程(cheng)(cheng)序的(de)準(zhun)備(bei)(bei)(bei)工作由采用自動程(cheng)(cheng)序準(zhun)備(bei)(bei)(bei)系(xi)統來進(jin)行，其質(zhi)量水平在很大程(cheng)(cheng)度上取決于準(zhun)備(bei)(bei)(bei)控制程(cheng)(cheng)序的(de)價(jia)格。
其它(ta)是(shi)人(ren)工(gong)控制設備時產(chan)生的加(jia)(jia)工(gong)誤(wu)(wu)差(cha)(cha)(cha)，這些誤(wu)(wu)差(cha)(cha)(cha)包括工(gong)藝系(xi)(xi)統的偶然(ran)誤(wu)(wu)差(cha)(cha)(cha)和系(xi)(xi)統誤(wu)(wu)差(cha)(cha)(cha)。全部加(jia)(jia)工(gong)誤(wu)(wu)差(cha)(cha)(cha)中系(xi)(xi)統誤(wu)(wu)差(cha)(cha)(cha)起主要作用，對精(jing)密機械零(ling)部件加(jia)(jia)工(gong)整體而(er)言，會(hui)引起一系(xi)(xi)列數控工(gong)藝系(xi)(xi)統誤(wu)(wu)差(cha)(cha)(cha)。
比如說間隙，其(qi)后果(guo)如同機床傳(chuan)動(dong)鏈中的(de)不(bu)(bu)靈(ling)敏帶，但不(bu)(bu)包括反(fan)(fan)向傳(chuan)動(dong)鏈間隙；不(bu)(bu)穩(wen)定傳(chuan)動(dong)的(de)放大系數；在控(kong)制程序磁(ci)帶上(shang)的(de)相位誤差(cha)；.傳(chuan)感器反(fan)(fan)饋的(de)周期性步進(jin)不(bu)(bu)穩(wen)定性，其(qi)主要形(xing)式是(shi)相位形(xing)式不(bu)(bu)穩(wen)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.
