ادامه مطلبMachining functions such as cutting, welding, grinding, deburring, milling and polishing have historically represented a relatively low percentage of robotic applications. In 2018, for example, welding and soldering, dispensing and processing (cutting, grinding, de-burring, milling and polishing) accounted for only 25% of total applications of industrial robots.
ادامه مطلبMetal cutting, grinding, drilling, boring, and other tasks are all part of machining. And as these activities are all "metal-on-metal," at some point, something must give. This "give" comes in the form of tool wear, where regular operation means that tools will lose surface, sharpness, and temper over time.
