Development of Robotic Arm Manipulator Control System for ...

The process of documenting and measuring for monitoring the tool wear in micromilling requires high accuracy. This process uses a Dino-Lite digital microscope to take pictures and is repeated every time after machining by removing the cutting tool from the spindle on the micromilling machine. Therefore, the development of a manipulator robot is made to simplify the process of monitoring the ...

Automatic Motion Generation for Robotic Milling Optimizing ...

Optimal and intuitive robotic machining is still a challenge. One of the main reasons for this is the lack of robot stiffness, which is also dependent on the robot positioning in the Cartesian space. To make up for this deficiency and with the aim of increasing robot machining accuracy, this contribution describes a solution approach for optimizing the stiffness over a desired milling path ...
