Abstract

Recent progress in robotics makes robots suitable for many different applications. Beside manipulative and installation applications, which are the most common for robot manipulator, milling can be performed as well. In the near future, robot manipulators, integrated with spindle, proper cutting tool and milling parameters could replace conventional CNC middle toleranced machining, especially for soft material end products. In general, tool life behaviour in milling with robots is not available or studied. Therefore, this work presents the analysis of HSS tool wear in milling MDF (medium density fibreboard) with an anthropomorphic robot. The focus is on the correlation of the tool wear and the workpiece position in the robot operation area. To analyse this, tests were performed in four different positions according to the distance between robot base and test milling position. Results show that increasing distance significantly affects tool wear, on account of vibrations, what shows completely different behaviour than stiff conventional CNC machine tools.
