Improvement of Productivity in Finnish Metal Industry in Cooperation with Employers’ and Employees’ Organizations

At the close of the nineteenth century, that is on the eve of colonial rule in Igboland, Igbo metal industry was flourishing. Production had attained a high level in the range and the quality of output. The output included agricultural equipment, traps and guns as well as title insignia and ornaments, mosdy made of copper and brass. The demand for die smiths' products were widespread and seemingly insatiable. To serve the need of dieir widely dispersed customers and patrons, Igbo smiths from Abiriba, Agulu Amokwe, Agulu Umana, Awka, and Nkwere undertook regular tours of parts of soudi-eastern Nigeria and even beyond – up to die Niger-Benue confluence area; past die Edo country to Ondo Yorubaland; and to the Bamenda district of die Cameroons. The superiority of Igbo metalworking led, in some of these places, to the demise of the local industry.

Process Forces

Industrieroboter bieten eine große Flexibilität und einen großen Arbeitsraum bei verhältnismäßig geringen Investitionskosten. Gegenüber spanenden Werkzeugmaschinen sind die Steifigkeiten und Bahngenauigkeiten von Robotern jedoch geringer. Dennoch bieten sie für die Holzbearbeitung großes Potential, da die Prozesskräfte gewöhnlich kleiner und die Toleranzen höher sind als im Metallbereich. Dieser Beitrag stellt einen Vergleich der erzielbaren Bauteilqualitäten bei der Holzbearbeitung mit Industrierobotern und Bearbeitungszentren vor.   Industrial robots provide great flexibility and a large working area at relatively low investment costs. However, their stiffness and path accuracy are generally lower compared to machine tools. Still, they offer high potential for woodworking, as the process forces are usually smaller and the tolerances higher than in the metal industry. This paper presents a comparison of the achievable component qualities in woodworking with industrial robots and machining centers.
