Abstract: In traditional metal sheet processing scenarios, the use of die cutting for blanking is a relatively widespread method. However, due to reasons such as long design and manufacturing cycles and high costs,stamping dies are only suitable for limited scenarios like large batch sizes or high-value-added products. For scenarios involving small batch sizes and complex work piece processing, robot-laser-cutting with high precision and flexibility has gradually become the optimal solution. Traditional manual teaching programming for robots is time-consuming and less precise, leading to an increasing number of users favoring offline programming technology for robots. Nevertheless, offline programming technology for robots has its own constraints: it cannot operate without the product’ s 3D model, offline programming data still require tool calibration after being imported into the robot and the actual cutting effects on work pieces may vary due to the overall layout’ s precision. As a result,offline programming technology has not yet fully replaced traditional manual teaching programming. Combine personal experiences and projects to elaborate on the advantages of using offline programming in robot-laser-cutting applications, the difficulties and key factors involved, as well as the current state of the industry.
