A matrix intelligent production line layout was proposed to meet the personalized customization machining requirements of engine parts for manufacturing enterprises.The development focusing on the functional analysis,overall scheme design,simulation and verification etc.of the production line was carried out.And intelligent production scheduling,machining,detection,assembly and warehousing were realized by integrating industrial internet,intelligent control,industrial robot,MES system and other advanced technologies.The site layout optimization and virtual debugging of the designed production line were carried out by the process simulation method.And the production line was built and successfully debugged according to the above simulation results.It is proved by practice that the intelligent production line is reasonable in design and stable in operation.So the expected design requirements with the production line can be met.And the whole process intelligent production for engine parts can be realized.
