The talent training mode of school-enterprise cooperation in Liaoning Vocational College of Light Industry provides students with enterprises suitable for their development. Zheng Jiyou entered the pilot workshop of Dachai Factory after graduation and became an equipment operator。

Zheng Jiyou still remembers the scene of the first day of work: "When I entered the workshop, I was overwhelmed by the neat rows of CNC processing equipment。At that time, he made up his mind: "While young, we must seize the rare opportunity to learn skills here and become a technical expert!"

Thanks to the skills he acquired in school and his passion for CNC machining, Zheng Jiyou's career got off to a smooth start。At the beginning of his entry, he humbly asked the masters for advice on operational methods, processing difficulties, tool cutting parameters and other practical experience, he recorded it one by one, and combined with what he learned in school and practice, and asked if he did not understand。

Day by day, the thick book is filled with dense notes, numerical control programming, mechanical drawing, tooling adjustment, tool selection and other skills are also rapidly improved。很快，Zheng Jiyou has skillfully applied the PowerMill CNC programming software to the programming of machining programs，He also mastered the characteristics of vertical and horizontal machining centers with multiple operating systems，Moreover, it can independently eliminate common faults of machine tools and assist maintenance personnel to analyze difficult faults，Gradually grow into the young backbone of the workshop。

"Contention" word as the head, a "war" fame break cocoon into butterfly

In his spare time, Zheng Jiyou volunteered to participate in the vocational skills examination, and successfully obtained the national vocational skills processing Center operator technician and milling (CNC direction) senior technician certificate。In July 2019, through the layers of selection, Zheng Jiyou entered the numerical control Competition training team formed by Dalian Federation of Trade Unions and participated in the 2019 Liaoning Province Workers' Skills Competition processing center Operation Competition on behalf of Dalian City。In order to the artisan dream in his heart, Zheng Jiyou was undistracted and trained hard。He gave up the weekend and high temperature holiday, from morning to night "bubble" on the machine tool to practice technology, carefully verify every line of procedures, every parameter。"Sometimes a workpiece down, from programming, processing, measurement takes 6 hours, the clothes on the body are often soaked with sweat.。"During that time, I trained from 8 a.m. to 9:30 p.m. in the workshop every day, went home and reviewed the theory, practiced software programming, and sometimes dreamed at night that I was memorizing problems and processing parts.。”

Sow and reap。Zheng Jiyou won the first place in Liaoning Machining Center Operation competition。Subsequently, in the 2021 Liberation of the company's staff skills competition, he also defeated the group and won the first place in the CNC machining competition。In 2022, on behalf of FAW Group, he participated in the CNC multi-axis Machining Competition of the Belt and Road and BRICS Skills Development and Technological Innovation Competition and won the second prize of the National Competition。

At the same time, Zheng Jiyou is also improving his personal management skills。In 2023 "Red Flag Cup" the fourth National machinery industry team leader management skills competition, he won the third prize。

The word "health" is to have the courage to take on the responsibility in the body

Practice what you learn and combine knowledge with practice。Zheng Jiyou will be a martial arts display to the production and processing process。His self-developed tool life statistics and tool length judgment methods for machining centers，Breaking through the neck technology of imported equipment，With zero investment, the phenomenon of tool punching and fixture damage and shutdown caused by the error of tool filling input is eliminated，Not only upgraded the production line LTE，And achieve accurate tool life control，Reduced tool costs。He designed the 6DM cylinder block production line fixture gas detection and error prevention device, solved the problem of manual clamping is not in place in the production process, and effectively reduced the processing scrap rate。

As the leader of the "post-80 QC team" in the processing workshop, Zheng Jiyou led the team members to solve many processing difficulties and pain points, and achieved remarkable results in quality improvement, efficiency improvement and cost reduction, successively winning the gold medal of the national machinery industry quality excellent management group twice。In the past three years, he has put forward and been adopted and applied more than 50 rationalization proposals and technical innovation projects, independently improved and produced more than 40 sets of tooling fixtures, saving funds for the company and creating economic benefits of more than 12 million yuan。

A hundred flowers are better than a single flower。"The strength of the team is the strongest!Only let the small partners around you have excellent business level, in order to enable enterprises to achieve technological progress and product innovation。Zheng Jiyou unselfishly taught and helped the team members。He relies on Kaichun provincial model worker studio training numerical control processing technology, improve the workshop staff numerical control processing operation level。He developed 3 courses and trained 11 apprentices, who respectively won the first, third and fifth place in the numerical control milling competition of Kimpu Craftsman Cup Skills Competition。In the past three years, he has trained and tutored apprentices, including 1 technician, 2 senior workers and 15 intermediate workers。He also returned to his Alma mater as an external counselor in the Department of Mechanical and Electrical Engineering and the lead creator of the complex Parts CNC Machining Master studio，Cultivate more than 10 students，Among them, 2 students won the first prize of "Mingcai Cup" National Industrial Digital Twin Technology Application Competition，2 students won the second prize of "Complex Parts CNC Multi-axis Linkage Machining Technology" in Liaoning Vocational College Skills Competition (the third place in the total result)，One student won the gold medal in the Challenge Cup Liaoning College Student Entrepreneurship Program Competition。It is particularly important that under his influence, the teachers and sisters have expressed that they will carry forward the spirit of hard work and endurance in the future study and life, enhance professional skills, practice excellent skills, and strive to become good young people in the new era who have ideals, dare to take on responsibilities, can bear hardships, and are willing to struggle。
