The definition of part-dependent hardware apparatus and software code, of primary importance, was obtained developing an original strategy aimed to solve accuracy problems in robotic machining.
The programming strategy and the robot reference frames alignment were mainly investigated to enhance robotic machining accuracy without adding external hardware or tailored mechatronic devices.
Special strategies for offline programming and alignment operation were developed. The manual robot
teaching strategy commonly adopted in Industry for hammers is a fast method but did not reach the required
tolerance and cannot guarantee the quality steadiness.
Such limits were overcame thanks to the OLP, through the definition of target points disposed on the theoretical final surface of the model with mathematical precision, the experimental analysis of velocities and accelerations, the minimization of the robot chattering and the development of an original on-line alignment strategy.
Due to the high mechanical properties of the material, special attention was paid to the definition of the
machining strategy. A modular and parametric software routine was developed to manage the iteration of the
paths in function of the cutting depth and of the deviation of workpiece shape by the ideal CAD geometry.
