Drawback of traditional dimensional tolerance

poor fit or reduced component performance.

The disadvantage of displaying traditional dimensional tolerance according to Sohu. com is that it may lead to poor fit between parts or reduce the performance of parts. This is because the traditional dimensional tolerance does not take into account the actual matching conditions, material deformation and errors in the production process, so it is often unable to accurately describe the accuracy and quality of solid parts.

the traditional units of length in China are Li, Zhang, ruler, inch, Xun, Fu, Zhi, Qi, Bu, Chang, Ya, Yan, Ji, Rail, Luo, Millimeter, Li, Minute and so on.
