New video: Final Exam Part 2 for Machinists, Summer 2024 (Turning)
Simulation of the IHK Final Exam (Exam conducted by Chamber of Industry & Commerce, Germany) Part 2 for Machinists, Summer 2024, CNC Turning is now available on YouTube:
- Watch the video: https://youtu.be/rMk0jaUg78w
In the Turning examination task this time, all machining operations had to be carried out with driven tools on chordal surfaces (G19 IP5). In particular, gaps in the cycle calls (G7x) had to be filled, where the candidates needed to understand the axes in the G19 plane (YZ). In contrast to milling, however, it was not necessary to program entire contour trains. Instead, they were required to determine individual coordinates for the “center tolerance” and ISO fits. There were further gaps for recesses, an internal recess and jump addresses in program part repetitions.

Newsletter June 2024
The exams are finally over and the summer vacation is just around the corner. But before you go fully into vacation mode, let’s take a look back at the exams – especially at the tasks given. What content was covered? What tricky challenges had to be mastered this year?Bye-bye exam stress, Hello summer!
Milling:
There were no major surprises in the milling exam. Of course, it was necessary to master the functions for switching the radius correction on and off and to apply the commands for soft approach and departure that have been changed since 2020.
In addition, contour points had to be read from the drawing and starting point coordinates had to be subtracted from the centre point coordinates, which were always dimensioned absolutely, to calculate I and J. Two fitting dimensions had to be determined, a rotational speed had to be calculated and some gaps in the cycle for thread milling (G88) and tapping (G84) had to be filled – similar to the previous winter exam.

GKE + CAM – Graphical Programming (Throwback 1989)
Today we look back on our product “GKE + CAM”, the forerunner of our current CNC software SYMplus™! This tool revolutionised “graphical programming”. With clear pictograms, the most complex geometries could be captured and combined with the raw part in the work plan. Production strategies such as roughing and finishing were implemented directly in tool paths, without the need for G and M functions.
Well-known personalities like the one in the photo, Johannes Rau (then Minister-President of NRW, later Federal President), were highly impressed. On the right next to him are Mrs. and Mr. Keller.
Fun fact: Rau was born in Wuppertal and was even mayor of his home town from 1969 to 1970.

Bergisches Competence Center for CNC and PLC Technology (Throwback 2001)
In May 2001, the “Bergisches Competence Center for CNC and PLC Technology” was inaugurated at BZI Remscheid!
This marked a strong partnership between KELLER, SPINNER, SIEMENS, and BZI, which provided the facilities and infrastructure (and with whom we still maintain a close friendship to this day!).
Together, we introduced state-of-the-art CNC programming into various industries. Thanks to practical courses and innovative tools such as ShopMill and ShopTurn from SIEMENS, skilled workers quickly familiarised themselves with the then-new technology. But it wasn’t just professionals; students also had the opportunity to immerse themselves in the world of metal technology and create their own workpieces.
