CASTILLO-CASTANEDA, E.; TRASLOSHEROS-MICHEL, A.  and  OKAZAKI, Yuichi. Depth Impact Control of an Electromagnetic Actuator for High Precision Engraving. Ing. invest. y tecnol. [online]. 2008, vol.9, n.4, pp.281-291. ISSN 2594-0732.

This document presents both the mechanical elements and the motion control of a novel three-axis metal engraving machine. The aim of this work is to improve the conventional high resolution engraving techniques that commonly use expensive piezoelectric actuators with reduced impact depth. Also, it is presented the depth impact control in open loop for an electromagnetic actuator (solenoid). A conical tool is fixed on the mobile part of the solenoid that moves toward the work piece when the solenoid is energized. This novel machine performs micro-impacts of controlled depth on metallic flat surfaces and it can be also applied to high precision machining processes. The machine was experimentally tested on steel work pieces using scanned pictures.
