PAL2020: How to rewrite old PAL programs.
With the reform of the PAL norms in 2020, quite a few changes came our way. G17 is now G15, G86 and G88 remain, but many new or modified cycle addresses have been added, and so on and so forth.
However, we found out through interesting exchanges with the participants in our new webinar series, “PAL2020: What’s Changing in Machinists’ Exams,” that the PAL2020 commands feel like deciphering hieroglyphics.
But since we’re not all likely to be Indiana Jones, we’d like to give you a little overview of the changes in this newsletter – To decipher the hieroglyphics, so to speak.
Here you can find a table with the comparison “PAL2008/PAL2012” and “PAL2020” (status spring 2023):
To the comparison: “PAL2008/2012 ↔ PAL2020” >
Well, now you can understand the hieroglyphs a bit better, but you still have a lot of programs that run with the old PAL standard, or more precisely, don’t run anymore. What about that?
One trick that is so easy and old that you might not even think of it is the search-and-replace function in SYMplus™. You can use it to rewrite anything that can be replaced one-to-one, like G17 with G15. And this is how you proceed:
1.
Open the program, which you have programmed in an older PAL coding, in the mode “PAL2020”. You will then get the message, “The NC program is faulty!” This is exactly what we want to change, so just click it away with “F10”. In your editor, the last block that does not correspond to the coding according to PAL2020 will now be marked. Here in our example, the exercise program “LAGER3” from the workbook “Plane Swing”, is the line “N65 G17 CR180 AR90”.
2.
Press the “F1” key to select “Search/Replace” and enter “G17” in the “Search for” field and “G15” in the “Replace with” field:
Then click “Replace All” to replace “G17” with “G15” throughout the document. Finally, apply this edit by pressing the “F10” key.
3.
Next, in our example, the line “N45 G48 G40 R10 Z0” is marked as incorrect, because after PAL2020 the commands for tangential approach and departure have also changed:
Replace them according to the same principle: “G48 G40 R” becomes “G40 G46 RR”. And then “G41 G45 D” = “G41 G45 DL”.
And already you have done quite a lot of work without having to trudge through the lines piece by piece.
Everything else (like changing cycle addresses) is explained on our support page:

6 steps to an organised Postprocessor list.
SYMplus™ provides a list of around 50 Postprocessors. In reality, you will hardly ever need all of them. Mostly you work with one or a few. So selecting the right postprocessor can prove to be a nuisance with such a large list. Here is a tip that can help you organise those Postprocessors efficiently: Create a second folder for postprocessor parameter sets, and copy the postprocessors you currently need into this folder. That’s it.
Here it goes:
Step 1: Open the “Work plan” operating mode (alternatively also “PAL simulator” or “Simulator”).
Step 2: Select “F1 File” > “F5 Management” > “F4 Postprocessor Parameter”.
Step 3: Mark the file(s) relevant to you and …

SYMplus™ Update 63 is now available to all customers with plusCARE™ and includes new features as well as great improvements.
Scale the font size in the editor of the simulators to 200% by default (e.g. for the beamer image of the teacher’s computer)
When creating PAL gap-filling tasks, store individual instructions for each gap in the text
Receive the new simulators for the SINUMERIK 808D control system
The exchange of revolver stations and individual allowance presettings for roughing, facing and grooving in turning operation was never so easy
In addition, many detailed improvements in the simulators for PAL2020, SIEMENS 810D/840D and HEIDENHAIN allow for more effective work. The use of mobile licenses and the sources for the creation of individual macro work steps (by customer order) have also been improved. Other sample programs have been revised according to PAL2020 (for new installation as part of the user data).
More information about Update >
Lastly, we want to pause and look back at the past year.
It was great to see that many events and meetings took place this year. It started with the BETT UK education fair in London in March and ended with the BZI Remscheid open day last month.
The fact that face-to-face meetings were more feasible again than in the past two years was also evident at the KELLER.Academy: close to 40 guests came to the Academy courses this year (in comparison: there were less than twenty in 2021). In addition, the KELLER.Academy celebrated its fifth anniversary and held (virtual) training courses in Pakistan and Mexico, both of which are far away. In September, we published the new “SYMplus™ license via the Internet”, with which you now only need one KELLER ID to let several users work with SYMplus™. And in October, a new edition of the workbooks was also published.
Look out for more new improvements next year!

Accessibility, Friendliness, Competence and Persistance.
Are you at a loss for ideas on how to solve your CNC related questions? Don’t worry! That is why we have an expert support team at your service.
And by that we do not mean an annoying hotline where you:
- spend what feels like hours on hold with a melody (which is guaranteed to give you an earworm), or
- you notice directly that the person has no knowledge of the subject at all.
Rather, this is about the support teams, like that of KELLER.Software, who really help you solve your problems.
Mr.Korthaus from the firm Feinwerkmechanik Marcus Röll in Wuppertal recently described KELLER support with the words: “Accessibility, friendliness, competence and persistance”. When he faced a technical problem because of the interface between the machine and the computer, “he was at a loss himself”, as he wrote in his review.
He went on to say: “In the course of solving the problem together, it had become clear that this problem was not easy to fix. And at this point I’m very grateful that KELLER support got involved and didn’t let go, so that we were in constant contact and were able to find a solution together.”
We would like to return our thanks to Mr. Korthaus at this point, who has confirmed to us with his kind review that we are not doing a bad job at all.
You can read the whole review from Mr. Korthaus here, as well as other interesting reviews from customers > https://cnc-keller.com/customers/

Still in service then and now
Do you own any old CNC machines? Or do you know such models from the past? Well, even if neither is the case, this discovery at the Bergische University Wuppertal is interesting for all CNC professionals. There is a Boehringer VDT DUC 560 lathe from 1996.
And the best part: it works! This is achieved by using the former CNCplus control from KELLER, which makes the workpieces turn.
In the video below, Mr. Cavallaro, the workshop manager of the Physics Mechanical Workshop at the university, takes great pleasure in programming this 25 year old machine.
Watch now and let us know your thoughts > https://cnc-keller.com/aktuelles/boehringer-vdt-duc-560-lathe-built-in-1996/

Practical Tip: Clever Cutting and Reclamping
The plan was quite simple. Cut a turned part to be machined on both sides from the bar and at the same time programme the second machining side. If the length of the blank is defined to such an extent that at the end, there is enough material to “cut” out of the protective zone for the chuck or the clamping jaws.
However, if you proceed as described, after the “cutting off” step it would result in the half-finished workpiece falling in the simulation as in reality the chip tray or a part catcher. Afterwards, the geometry is no longer available in the working plan for further machining.
But what is the solution then? The following practical tip gives you the answer:

Tricky Production Order?
With renewed energy from the holidays, we are now getting back to work. To support you even more confidently and effectively than before, a very informative training session was held for the KELLER.Software team last month. The main focus was on you, our customer, and how we can help you more effectively in the very first telephone conversation.
Speaking of support: Recently, Schmidt Zerspanungstechnik GmbH approached us with a very fascinating task…
For two counter-rotating 3-flute flat threads on a spreader roll (Ø152, length approx. 3m), the control on their machine does not offer a suitable cycle.
The solution was quickly obvious: a macro needs to be programmed in SYMplus™. This macro will rough and finish the threads with normal grooving steels in many small infeeds. Since this was initially a one-off order for the company from Herdorf, it was created together with the customer via Zoom meeting.
Are you familiar with such tricky production orders? Do you have trouble finding a solution on your own? Then get in touch with us using the form below. KELLER.Software team will be happy to help you.

Summer slump? Not with us!
No matter whether it is a long trip or a vacation at home on the balcony, the KELLER.Software team wishes you a wonderful and relaxing summer season.
While you are hopefully enjoying your well-deserved vacation or have already enjoyed it, we used the time to further develop ourselves internally.
For example, we launched our first ( to be regular in the future) employee survey, which focused on how comfortable the individual employee feels in the company and with his or her colleagues. Because just as the relationship with our customers is important, the working atmosphere is also of great importance for a healthy company – and of course you, our customer, will also benefit from this.
That’s why the outcome from the survey was all the more pleasing: Everyone in the KELLER.Software team supports each other and we get on very well together.
In addition to this, our sales department is also undergoing training to make your experience with us even more pleasant.
If you want to take advantage of the summertime just like we do, take a look at our KELLER math software, TECHNICplus™. With it, you can brush up on your math skills in a fun way.
