AUTONOMOUS MACHINING – RECENT ADVANCES IN PROCESS PLANNING AND CONTROL
Journal Title: Journal of Machine Engineering - Year 2019, Vol 19, Issue 1
Abstract
While autonomous driving has come close to reality over the recent years, machining is still characterised by many manual tasks and prone to costly errors. In this article, an overview is given about the potential of autonomous machining and uprising technologies that support this vision. For that purpose, a definition of autonomous machine tools and the required elements is presented. Next, selected elements of an autonomous machine tool, e.g. sensory machine components and control loops, are discussed. Finally, some insights into ongoing research projects regarding the use of machine learning for process planning and control are given.<br/><br/>

ENHANCING LASER STEP DIAGONAL MEASUREMENT BY MULTIPLE SENSORS FOR FAST MACHINE TOOL CALIBRATION
The volumetric performance of machine tools is limited by the remaining relative deviation between desired and real tool tip position. Being able to predict this deviation at any given functional point enables methods fo...
Evaluation of different approaches to 3d numerical model development of the contact zone between elementary asperities and flat surface
This paper presents two triaxial finite element (FE) models: a “full model” and a “quarter model”, representing the contact between the specimen’s rough surface and the ideally smooth and flat surface of the punch. Model...
INVESTIGATION OF A HIGH-FORCED COOLING SYSTEM FOR THE ELEMENTS OF HEAT POWER INSTALLATIONS
The studies of the ultimate thermal flows have been carried out in metallic and poorly heat-conducting porous structures, which operate when gravitational and capillary forces act jointly and cool various devices of ther...
DETECTION OF WEAR PARAMETERS USING EXISTING SENSORS IN THE MACHINES ENVIRONMENT TO REACH HIGHER MACHINE PRECISION
This paper presents methods to plan predictive maintenance for precision assembly tasks. One of the key aspects of this approach is handling the abnormalities during the development phase, i.e. before and during process...
DECOMPOSITION ALGORITHM FOR TOOL PATH PLANNING FOR WIRE-ARC ADDITIVE MANUFACTURING
Three-axis machines are limited in the production of geometrical features in powder-bed additive manufacturing processes. In case of overhangs, support material has to be added due to the nature of the process, which cau...
