This class explores how industrial robots enable advanced capabilities and motion for machine tending. Robotic machine tending uses robots and peripheral devices, such as end effectors, to load and unload materials and parts from machining equipment. Machine tending may also be used for some secondary operations like inspection. Machine tending provides the accuracy and repeatability necessary to handle objects without damaging any finished products.
An understanding of robotic machine tending is important for working with industrial robotics and modern manufacturing applications. After taking this course, users will understand the technologies, systems, and operations associated with machine tending.
