摘要
在传统的金属钣金类加工场景中,使用模具裁切落料是比较广泛的加工方式,但因模具设计存在制造周期长、成本高等问题,故仅适用于大批量或高附加值产品等有限的场景中;对于小批量及复杂工件加工的场景,拥有较高加工精度及柔性化的工业机器人激光切割应用已逐步成为最佳解决方案。由于传统的工业机器人手工示教编程耗时长、精度偏低,因此工业机器人离线编程技术得到越来越多用户的青睐。然而,工业机器人离线编程技术自身也存在诸多制约性因素:如无法脱离产品3D模型图、离线编程轨迹程序导入工业机器人本体后仍需要对刀校准,以及在实际工件上完成的切割效果也会因整体布局的综合精度影响而表现不一,因此离线编程技术至今尚未能全面替代传统的手工示教编程。将结合个人经验与案例,阐述工业机器人离线编程在激光切割应用中的使用优势,涉及的难点与关键因素,以及行业应用现状。
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.
