Abstract:
Machine failure modes are presenting a major burden to the operator, the plant, and the enterprise causing significant downtime, labor cost, and reduced revenue. New technologies are emerging over the past years to monitor the machine’s performance, detect and isolate incipient failures or faults, and take appropriate actions to mitigate such detrimental events. This paper addresses the development and application of novel Prognostics and Health Management (PHM) technologies to a prototype machining process (a screw-tightening machine). The enabling technologies are built upon a series of tasks starting with failure analysis, testing, and data processing aimed to extract useful features or condition indicators from raw data, a symbolic regression modeling framework, and a Bayesian estimation method called particle filtering to predict the feature state estimate accurately. The detection scheme declares the fault of a machine critical component with user specified accuracy or confidence and given false alarm rate while the prediction algorithm estimates accurately the remaining useful life of the failing component. Simulation results support the efficacy of the approach and match well the experimental data.

Abstract:
In presented paper, the screwdriver’s electric power consumption studies depending on the corresponding fixed threaded joint’s assembly time are carried out. So far there are no recommendations from the tool manufactures for screwdriver’s optimal operating modes (the conclusion is made on the base of the attached instructions which provide instrument manufacturers), when evaluating this aspect upon taking into account the electrical power consumption and assembly time for different types of fixed threaded joints (wood, metal, plastic, etc.) and also taking into account obtainable tightening moments. In the examined literature sources which deal with the opportunities concerning the optimization of the automated assembly processes of fixed threaded joints, not enough attention is paid to the reduction of the instrument’s energy consumption which is one of the main tasks in the industrial process because it directly impacts production costs.

Abstract:
This diploma thesis deals with the problem of designing an automatic robotic workstation for automatic tightening screws connections seatback – seat and belt buckle. The research part of this thesis deals with current trends in the automotive industry, especially with the problem of assembling seats part, with focus on screwing. The design part of this thesis maps the process of designing two variants of an automatic robotic workstation. Special attention was given to the process of choosing the right industrial robot for the task, as well as to the construction of the end-effector and of the resulting 3D data. The right version of the workstation for the consecutive implementation was then chosen based on multi-criteria evaluation. The finishing touch of this thesis is a risk analysis for the implemented workstation.

Abstract:
Today the torque controlled tightening method for screw assembly is an established process in industries undertaking large scale productions [12]. In this tightening method an instability of friction during the tightening procedure leads to an imprecise stop of the electronic tightening tool affecting the preload. Besides this heavy noise emission occurs due to vibrations. Because of shorter and shorter cycle times in automated screw assembly, higher precision requirements, new surface pairings (e.g. Cr(VI)-free) with changed coefficients of friction and more complex assemblies with difficult access to the joint, result in an increased number of torque vibrations on automatized screw assembly (also called stick-slip). Due to highly interconnected production flows, the productivity is hereby significantly interrupted. This means significant financial loss because of a small screw which stops the entire production line. This contribution entitles the reasons for the origin of torque vibrations as well as advices for elimination.
