Aviation Industry Hafei Menxianrui: The Story of \”Dameer\”

The eyes of Men Xianrui, a craftsman in the Harbin aircraft machining workshop of the Aviation Industry, is a ruler, and it is a \”vernier caliper.\” In football, everyone is accustomed to calling the goalkeeper the \”gatekeeper\”. Because his surname is Men, and because he is a part-time proofreader of process procedures, and has a precise vision and perfect control, his colleagues gave him a nickname – \”Damen\’er\”.

If you want to process qualified parts, the preparation of correct process regulations is a prerequisite. \”Denmener\” proofreads the process regulations to ensure that the source of the entire processing process is correct. Although he is a part-time proofreader, his sense of responsibility and technical skills are that of a \”full-time\” one. To do this job well, he has the \”Three Treasures\”. First, read all kinds of technical documents dynamically and have a basis in mind. The second is to have rich work experience and be proficient in various types of parts processing. The third is to record, summarize, and improve to prevent the same mistakes from happening again. Proofreading work requires extreme care, because problems often occur in small and inconspicuous places, which also places extremely high demands on the \”eyesight\” of the proofreader.

Once, craftsman Xiao Zhang approached \”Denmen\’er\” confidently: \”Brother, help me look at this job. Is the plan feasible?\” Opening the online process, \”Denmen\’er\” immediately immersed himself in the process. In the procedure, \”The plan is great, but this job will definitely not be delivered.\” \”Dammen\” said with a frown. It turned out that Xiao Zhang only considered the requirements of the drawings when selecting materials, but ignored the constraints of the latest version of the technical documents, which was wrong from the source. \”It\’s hard to guard against it!\” Xiao Zhang sighed. Soon, \”Denmen\’er\” informed the whole group of this \”lesson\”. He said: \”The safer the place, the easier it is to turn a blind eye and the easier it is to make mistakes. Everyone must be serious, serious, and serious again.\”

In addition to avoiding problems in advance, \”Damener\” also has a keen eye for analyzing technical quality issues. Once, technician Xiao Liu optimized the CNC machining program in time according to the operator\’s needs. As soon as the machine tool was started after optimization, Xiao Liu and the operator discovered that the tool path was wrong.

\”The changed program has been checked by computer simulation and there will be no problems.\” Xiao Liu fell into deep thought, but he could not find the cause of the problem.

“Let’s take a look at ‘Damen’er’? His eyes are ‘poisonous’.” said the operator. Arriving near the machine tool, \”Damener\” immediately opened the program to look for clues. While inspecting the program, he asked Xiao Liu about the operation process just now.

A few minutes later, he said slowly: \”In addition to what you said, is there another auxiliary line?\”

\”Yes, yes, yes, how do you know?\” It turns out that the problem occurred in this auxiliary line. Online, after finding the cause, the problem was solved.

This is the story of \”Damener\”. By ensuring good product quality, Damener can hold on to it, be reliable, and never tire of it.
