Opis:
Activities of maintenance services cover not only the performance of ongoing repairs, but, above all, the prevention of failures and downtime. Adopting preventive measures to maintain machinery and equipment in manufacturing enterprises has a significant impact on the timely execution of orders, which is why monitoring the state of the machine park is becoming common in robotic manufacturing enterprises. Currently, the most frequently observed diagnostic parameters relate to machine vibrations. Information on exceeding the permissible thresholds allows for appropriate reaction of maintenance services aimed at minimizing unplanned downtime. The diagnostic aspect is beyond dispute here. However, there is a question whether the vibration signal can additionally be a carrier of information about the production process - information that can be used at the stage of technological process assessment, or even at the stage of process control? Searching for the answer to this question, one of machining centres for mass production of glued panels in the furniture industry was analyzed. Information obtained from maintenance services was confronted with information from standard vibration measurements. The article is an attempt to answer the question of how to properly use at the management stage knowledge of vibration signals generated by motors mounted on the production line.

Opis:
In Iran, furniture is mainly manufactured in small workshops, where most activities are performed manually. This study was conducted among workers of furniture workshops to determine prevalence of musculoskeletal symptoms and to assess ergonomic working conditions to identify major risk factors associated with musculoskeletal symptoms. In this study, 410 randomly selected furniture workers participated. The Nordic questionnaire and an ergonomics checklist consisting of 6 sections were used as data collection tools. An index was calculated for each section of the checklist. Action categories indicating the priority of corrective measures were also defined. The highest prevalence of symptoms was reported in the knees (39%), lower back (35.6%) and wrists/hands (29.5%). It was found that manual material handling, poor workstation design and awkward working postures were associated with the reported symptoms in these regions (OR 1.77–4.52). Poor general working conditions and work organization showed association as well. Any interventional measures should focus on these areas.
