Abstract: A laser cutting method for irregular parts based on machine vision includes: (A) obtaining and numbering vertices of all parts on the layout diagram; (B) planning a part vertex set and an empty cutting path vertex set; (C) obtaining a shortest empty cutting path and the empty cutting path vertex set with the shortest empty cutting path; (D) cutting the parts one by one according to an order obtained by the CPLEX algorithm. This application further provides a laser cutting system.

Abstract: Disclosed are an optimization method and a system based on a screwdriving technology in mobile phone manufacturing. The method comprises: acquiring mobile phone machining data; establishing a technological framework; determining initial screwdriving technological parameters and a range of the screwdriving technological parameters by a neural network algorithm; building a digital twin model of a screwdriving device by a digital twin technology and establishing a virtual-real synchronous real-object simulation platform to make a real object and a simulation model run synchronously; integrating the digital twin model of the screwdriving device with each module to synchronize data of the screwdriving device with data of each module; and if screwdriving feedback information is abnormal, optimizing the screwdriving technology according to the range of the parameters. A real-time running state can be tested and technological parameters can be monitored during technological process, and parameters in the screwdriving technological process can be adjusted in time.
