3 Steps to Rotary-Symmetric Contour!
For pocket or island contours, the entire geometry often needs to be created from A to Z. But what about rotationally symmetric contours? That should be much simpler, right?
With SYMplus™ CNC software, you can do it in just 3 quick steps:
1️⃣ Create 1/6 of the contour – saving you time and effort.
2️⃣ Mirror the created section – now you have the other side.
3️⃣ Mirror and rotate the whole thing around the other axis – and voilà, your rotationally symmetric geometry is complete!

Newsletter December 2024
The skilled workers of tomorrow, the day after tomorrow, and beyond.
2024 – what a year! In the CNC industry, challenges are part of everyday life: every workpiece presents new tasks, and each machine requires an individual approach. Yet, new technologies can sometimes overwhelm us. We understand that. CNC machinists are playing an increasingly central role in Industry 4.0. As machines become more automated and connected, the demands on training and skills for professionals are changing as well. That’s why, once again this year, we’ve worked hard to provide you with not just a “tool,” but solutions that integrate smoothly into your daily work – without unnecessary complexity that costs time, money, and nerves. We believe in thoughtful, small steps that make the biggest difference in the long run. For the professionals of tomorrow, the day after tomorrow, and beyond.
But before we say “goodbye” for this year, we’d like to take a brief look at the winter final exams for CNC machinists. What challenges did candidates face? What was new? On our YouTube channel (@CNC KELLER GmbH), you’ll find a simulation of each exam (Turning and Milling) using our CNC software. It’s perfect for anyone looking to prepare for upcoming exams, or for those who want to analyze the exam workpiece in more detail. You can find the links to the videos under this text (note: The videos are available in German only).
To wrap up this newsletter, we’d just like to say thank you: Thank you for your trust, your collaboration, and for helping us drive the CNC world forward in 2024. Our team will be taking a short break from December 23, 2024, to January 1, 2025, but we’ll be back with renewed energy on January 2.
We wish you restful holidays and a fantastic start to the new year!
Your KELLER.Software Team
Exam CNC Machinist (Part 2, Winter 2024)
Turning:
The turning exam part presented interesting challenges: It involved plan and longitudinal turning, finish machining with program repetition, and working with driven tools.
A highlight was an eccentric circular pocket with an island, programmed using G73 and G79. Other tasks included machining an internal contour, setting allowances, and precisely machining an internal thread.
Milling:
The milling exam piece for CNC machinists in Winter 2024 had a lot to offer: from an external hexagon with polar coordinates to tricky internal contours, circular pockets, and drilling. Programming with G-codes such as G11, G15, and G23 also played a key role.
An important change from previous exams: The separate work plan sheet was replaced by explanatory comments directly in the program, greatly improving orientation.
