I have been working in FAW Car Engine and Transmission Manufacturing Center as a mechanical engineer since August 4th, 2010. I was the project manager in charge of the machining production line for the transmission cases. Since August, 2014, after the final acceptance of the machining production line, I have been working right inside the plant, taking charge of the 4GC engine cylinder head machining line, which has already been in the mass production period. As a processing engineer, I need to solve all kinds of problems to guarantee the cylinder heads qualified. I also need to optimize the machining process like cutting parameters, changing cutting tools and cutting tracks, and adjusting NC programs. Reducing the cost of tools is also a must, and when there are design changes of the product, I need to write new programs adding to the machining program.I was the process engineer of 4GDZN cylinder head machining line at the same time.Since Novemebr 2016, I have been in charge of a new project meanwhile, which aimed at changing the 4GDZN cylinder head line to machine 4GC cylinder heads.(Right in progress)
