We are specialized in the calculation, evaluation and optimization of cams and indexing cam gears, the simulation and dynamic optimization of multiple concurrent motions controlled by cams, servo drives and linkages ("collision optimization"), the dynamic optimization of motions (motion design) and the synthesis of mechanisms.
For that, we offer powerful cam and mechanism design software and consulting (calculation service, trainings etc.).
We improve performance, speed and durability of machines.
In short: We make machines faster, quieter, more powerful and more efficient. This saves money, your money.

Most machines are taylored for the needs of your customers and for given product formats.
Delivery times are very short and fixed, but your customers reveals important parameters very late.
Customers request high machine performance, machines must be faster than their predecessors, and they want high stability in the machine's processes.
The cycle speed was fixed between sales and customer, before the machine was engineered.
Do you know that? This is what many of our customers experience.
When writing quotations you need a safe statement about the reachable cycle speed. If you promise too much, the engineers will not be able to stick to your promises, and you will have disputes with your customer, workovers and expensive installer applications at the customer's site. On the other hand, if you are too cautious, your competitor will win the job with a more courageous quotation.
In engineering you profit from good and quickly done mechanism and motion design, cam calculation and servoprogramming. The first shot should be an almost perfect design and fully exploit the potential of your machine. You cannot make lengthy studies or build prototypes because it would cost too much, and because the delivery time is too short.
When mechanism layout, cam design and motion design are done and the machine is constructed, the production needs data for cutting the cams, and PLC programmers need data sets for programming the drives.
With our software:
Mechanisms can be modeled in OPTIMUS MOTUS with kinematics, loads and smooth motions with few mouse clicks. CAD models are not necessary for that. In a few minutes you estimate whether a product can be processed within a given cycle time or not, which drive torques you have to deal with and what roller and cam durabilities can be expected.
The software OPTIMUS MOTUS is best suited for feasibility studies in mechanism, cam and motion design.
Look here for ...
If you already have a CAD model for your machine, you can transfer the geometry into OPTIMUS MOTUS and make a simulation model. You quickly design super-smooth motions in a very powerful grafical motion editor for gaining high machine performance, while in parallel you check for collisions with animations.
The optimization loop "change motion design", "calculate loads and durabilities", "check for collisions" which we call "collision optimization" is extremely efficient in OPTIMUS MOTUS.
By calculating maximum and effective drive torques, forces and torques in links and the pressure of Hertz in cam links, cam and roller durabilities and the attainable cycle speed can be estimated quite well.
The versatile motion design methods in OPTIMUS MOTUS release the full dynamic potential of your machines.
When developing motion controls, OPTIMUS MOTUS is like a navigation system.
You always know where you are and get home directly and safely.
With consulting and calculations:
First of all, we want to provide you with good solutions for your cam and mechanism challenges, and we want to provide them quickly.
If it is really urgent, that may even be overnight. Two examples:
1.) Once, during commissioning on site, one of our customers realized that he needed an additional cam-driven assembly in a machine to prevent articles from falling over. The engineers just had been too optimistic before. Overnight we designed a mechanism, sent an animation to the engineers for verification and provided NC files the next morning for cutting the cams on the milling machines available on site. This way, our customer lost almost no time.
2.) Another time, a company was not able to reach the promised cycle time for a complex 8-axis transport unit with his own software. His customer already was about to cancel the order when threatened when the company found us as specialist for dynamic motion design. Focused and we some night shifts, we developed a new motion design software for the transport unit in only few weeks. With this software the transport unit moved fast enough. So we saved the turnover for our customer with our effort. When we had some more time after that, we improved the motion design even more, and our customer celebrated follow-up orders.
We look for solutions and think transversely to find them.
When we find during an optimization that there are alternative, maybe better approaches, we follow them and make suggestions, even if that should not explicitely be part of our job. If, for some reasons no one could foresee, your specifications cannot be implemented, we look for alternative ways to solve the underlying problem.
For calculations and consulting on cams, indexing cams, mechanisms and motions, we take advantage from 40 years of practical experience.
An example: a bending machine produced pipe clips with 70 cycles per minute using ordinarily designed cams. By optimizing the cams with motion design and collision optimization we improved speed up to 250 cycles per minute and, moreover, could reduce wear.
For your support we offer:
Calculation and Consulting:
Since 1972 we calculated more than 14000 cams and mechanisms and implemented dozens of customer-specific user interfaces for our mechanism software.
A small selection of projects from our long-term practice gives insight in what we do:
Today's Nolte NC Kurventechnik GmbH emerged in 1994 from the engineering office Günther Nolte.
Ing. grad. Günther Nolte (1929-2001) had been employed by several companies since 1954 and was entrusted with the development of cam-controlled machines. In 1965 he started his own business to design special machines.
At that time, one still drew cams on the drawing board on tracing paper, grained them on sheet metal, cut out the cam contour and filed it manually. With such templates, the cams were then prepared for use on a copy milling machine. Even the best worker could not avoid with his fingertip small, with the eye unrecognizable waves in the cam shape. The resulting interference accelerations limited the speed of the machines.
At the beginning of the 1970s, the first path-tracking NC milling machines were introduced, and Günther Nolte realized that it was possible to produce much more precise, smoother cams without waves, which would allow machines to run much faster.
So in 1972 Günther Nolte bought his first computer, a Diehl Algotronic, as a purchase for life. Four weeks later, the realization prevailed that the calculator was too small, and exchanged it for a Diehl Alphatronic. At that time computers were still very expensive, more expensive than cars, and it was very unusual to own a computer as a freelance engineer. Computers existed only in data centers of universities and large companies. With the Diehl Alphatronic Günther Nolte developed the first programs to calculate cams, e.g. for screen printing machines or industrial sewing machines. Input was read from tape, and manufacturing data for NC machines were also exported as punched tape.
His main focus - making machines faster or more dynamic - is still very important today.
Günther Nolte was active at this time in several VDI committees of the transmission technology and also participated in the development of the VDI guideline 2143 (standardized motion laws), on which since 1980 many cam technicians fall back.
In 1979, even the Diehl Alphatronic became too small, especially too slow for the growing volume of orders, and on 23.12.1979 came the basic desktop computer Tektronix 4052 into the office. 54 kilobytes of memory - amazing!
Rainer Nolte, son of the company founder, at that time 13-year-old pupil, today owner and managing director of Nolte NC Kurventechnik GmbH, had his fun with the device. He had particular talent in mathematics, physics and computer science and liked to read books about operating systems and compilers (just which guys do). When his father did not need the computer, he first programmed games, later compilers, and even made a few of his programs with the "Jugend forscht" competition. By the end of 1980, he had developed a compiler to translate his father's cam programs from Alphatronic to Tektronix 4052, and that really worked! This way, he reduced the time for calculating a couple of cams from 7 hours to 30 minutes!
Now that Rainer Nolte was familiar with the Tektronix 4052 and the cam software, he improved the cam calculation programs in the afternoons, when school was out. For example, features were added during this time to consider linkages.
Since 1984, Rainer Nolte has participated in several VDI committees of cam and mechanism technology and regularly appeared as a speaker at the VDI mechanism conferences, also several times at the SPS / IPC / Drives and other conferences or colloquia. From 1985 to 1991 Rainer Nolte studied mechanical engineering and became a graduate engineer.
In 1989 he began a second degree as a computer scientist and graduated in 1996 with a diploma. The combination of mechanical engineering - solid steel, spatial imagination, mathematical derivations - and computer science - abstract logic, algorithms - still make up our work today. We connect two worlds. We work together with designers, manufacturers and programmers.
In 1985, the Tektronix computer became too small. At some point, every computer is too small ...
So we found the entry into the UNIX world, the forerunner of Linux, first with a Cadmus computer, later with HP workstations of the series 9000. Rainer Nolte re-developed the cam and mechanism software in C. This software first got a menu-driven user interface, then the trademark "OPTIMUS MOTUS", and we began to distribute OPTIMUS MOTUS software licenses. Until then, we had used our software solely to perform cam calculations as a service or to support cam production orders. Now we wanted other engineers to calculate with our software as well.
Rainer Nolte improved the OPTIMUS MOTUS software ever more and added new features to it, e.g. for kinematic simulations, force and torque calculations (kinetostatics), indexing cam calculations, graphic motion design, linkage analysis, mechanism synthesis, numerical optimizations, spatial linkages, servo drive layouts, source code generation for PLC projects and many new features for motion design including many new laws of motion. From 1992, the software OPTIMUS MOTUS was ported to the PC world first on DOS, then on Windows 3.1 and has since been running on every Windows operating system (95, 98, NT, 2000, XP, 7, 8, 10 and more).
Today OPTIMUS MOTUS is used worldwide with a German and English language interface.
OPTIMUS MOTUS has a graphically oriented user interface and is constantly being improved and extended today.
We continue to perform cam calculations and motion simulations on our behalf and distribute licenses for the software we have developed.
Training, hotline and update service, individual software adjustments and seminars on mechanics complete our offer.
Our aim is to make machines faster, quieter and more durable.
Especially the extensive and practice-oriented methods for motion optimization, which make OPTIMUS MOTUS a unique and effective tool for machine development, help us with this.
