Abstract
The practical laser-guided deep-hole boring tool of 110mm diameter is produced for application and higher performance on the basis of the experimental results of the prototype tool. The practical tool consists of a counter-boring head, piezoelectric actuators for its attitude control, an active rotation stopper and a laser system for detecting its attitude. Experiments are conducted to examine the performance of this tool in detail using a duralumin (A2017-T4) workpiece with a prebored 108-mm diameter hole. To improve guiding accuracy, a guiding axis is optically arranged to bring in line with a desired one. Rolling of the tool is restricted by a rolling proof apparatus for detecting and controlling its attitude precisely. Results show that the practical tool can be guided to go straight through along the desired axis. The tool can be practically used to bore a precise hole using a rolling proof apparatus.
