Adaptation and Learning for Manipulators and Machining
… manipulators, with a focus on the application of machining. Industrial robots offer a flexible and cost-efficient alternative to machine tools for machining, but cannot achieve as high accuracy out of the box. This is mainly caused by non-ideal properties in the robot joints such as backlash and …

Shearing, ploughing, and wear in orthogonal machining
Under normal machining conditions, cutting forces are due primarily to the bulk shearing of the workpiece material in a narrow region called the shear zone. However, under certain conditions, such as finishing cuts or a worn tool, force components due to the rubbing and ploughing of the edge or …

Rotary-linear axes for high speed machining
This thesis presents the design, analysis, fabrication, and control of a rotary-linear axis; this axis is a key subsystem for high speed, 5-axis machine tools intended for fabricating centimeter-scale parts. The rotary-linear axis is a cylinder driven independently in rotation and translation. This …
