The milling exam task had no major surprises: Switching on and off functions of the radius correction and the commands for soft approach and departure that have been updated since 2020, had to be mastered. Reading contour points, calculating start point coordinates, determining two fitting dimensions, calculating rotation speed and filling in gaps in the cycle for thread milling (G88) and tapping (G84).

In 2012, Mr. Schenk and Mr. Ekrem from FASTNER GmbH demonstrated their skills as the first and second prize winners in the training for cutting machine operators (specialising in milling) in their area. Particularly impressive: Mr. Schenk secured the title of Baden-Württemberg state winner!
Their final workpieces? Programmed with the KELLER software “SYMplus” (then still known as “CNCplus”) and manufactured by the HAAS TM-3P – the very machine they are posing in front of in the photo.
