Obrábění prostorových objektů pomocí průmyslového robotu / Robot machining of three-dimensional objects

Kolář, Bronislav January 2013 (has links)
This diploma thesis deals with the design of robot machining of three-dimensional objects. Used method is Part to tool, in which robot holds the part in its gripper and with stacionary clamped mill, machines the part. Overally three parts for machining are designed, everyone of them shows the different style of machining. Every machining operations are described in details. For their creation was used program Mastercam. Furthermore is described transfer of the data for industrial robot using program Robotmaster and recomanded algorithm for creation of similar tasks. The design of simplified workplace for demonstrative show of the milling of all the parts is also solved.
