The Precision Engineering Laboratory – LMP – is one of the most nationally and internationally renowned laboratory at Mechanical Engineering Department of Federal University of Santa Catarina. LMP was established in 1990 due to the need of Mechanical Engineering course structure modernization, making good use of the knowledge and experience from the old Machine-tool Laboratory – USIMAQ.The Precision Engineering Laboratory develops technological researches in conventional machining with defined and non-defined geometry tools, also aiming at precision and ultraprecision machining, emphasizing turning, drilling, reaming, milling, grinding, lapping, burnishing, electroerosion, flow drilling, conformation threading and others. LMP also develops researches in ultraprecision projects and machine-tool building scopes, mainly in microdisplacement and linear and angular micropositioning based on computer assisted aerostatic bearing, aiming machine-tools and metrology devices.Among the main equipments available at LMP, there are conventional and numerically controlled lathes and milling machines, drilling machines, grinders, lapping machines, boring machines, one ultraprecision lathe, piezoelectric platforms for forces measurement on turning, milling and drilling, machining database acquisition system and equipments for results measurement and evaluation, as well as a full computational support structure.A new research area is related to LASER materials processing, based on a 10kW fiber LASER source for welding, cladding and additive manufacturing researches.There is also an intense interchange between LMP and national and foreign research institutes like institutes from Kassel, Ilmenau, and Braunschweig Technician Universities, as well as graduation and post-graduation students bilateral interchange between LMP, FhG – IPT and the Aachen Technician University.
