探讨机械加工精度的影响与控制

The discussion on influence and control of machining accuracy

任何机械加工的工件从初始加工到最后检测合格并投入使用,都需经过一系列步骤,其过程中有许多因素都会影响工件的质量。因此,为了在最大程度上避免或减少各种可能影响加工精度的因素,机械加工前需要对加工过程缜密考量以求在最大程度上加以控制。本文集结机械加工行业中所积累的多种优良经验及一些失误的前车之鉴,针对影响机械加工精度的各种主要因素进行分析,并提出了一些能够在最大限度上降低机械加工误差的几项具体措施。

Any work - piece machining should have a multiple - step from initial processing to finally detection of qualified and put use, so many factors could affect the quality of a work - piece. Therefore, to avoid or reduce the factor affecting machining accuracy, the working process should be considered carefully before machining, so that to maximize the process control. This paper analyzed various main factors affecting machine - working accuracy by con- centrating good experiences and mistakes of past, and some practical measures were suggested which could reduce machining error maximally.
