Compliance error compensation in robotic-based milling
The paper deals with the problem of compliance errors compensation in robotic-based milling. Contrary to previous works that assume that the forces/torques generated by the manufacturing process are constant, the interaction between the milling tool and the workpiece is modeled in details. It takes into account the tool geometry, the number of teeth, the feed rate, the spindle rotation speed an...
متن کاملIncorporating target registration error into robotic bone milling
Robots have been shown to be useful in assisting surgeons in a variety of bone drilling and milling procedures. Examples include commercial systems for joint repair or replacement surgeries, with in vitro feasibility recently shown for mastoidectomy. Typically, the robot is guided along a path planned on a CT image that has been registered to the physical anatomy in the operating room, which is...
متن کاملError measurements for flank milling
This paper presents and compares methods of error metrics used to measure the error for the flank milling of a machined ruled surface. The aim of this work is to propose a new scheme for error approximation that is easy to implement and gives better error assessment when using optimization techniques to determine tool position. We propose using as the error calculation an approximation to the d...
متن کاملA Statistics-Assisted Fuzzy-Nets-Based In-Process Tool Wear Prediction System in Milling Operations
This paper describes a fuzzy-nets approach with the assistance of a statistical model (multiple regression) to create an in-process tool wear prediction (S-FN -ITWP) system, the goal of which is to predict tool wear in milling operations under cutting conditions determined by feed rate and depth of cut with cutting force detected through a dynamometer. After the S-FN-ITWP system had been traine...
متن کاملMicrostructure-sensitive flow stress modeling for force prediction in laser assisted milling of Inconel 718
Inconel 718 is a typical hard-to-machine material that requires thermally enhanced machining technology such as laser-assisted milling. Based upon finite element analysis, this study simulates the forces in the laser-assisted milling process of Inconel 718 considering the effects of grain growth due to c0 and c00 phases. The c0 0 phase is unstable and becomes the d phase, which is likely to pre...
