Training and Education

The design of movements, cams, indexing cam gears and servo drive trains is crucial for machines' performance and durability.

Well-designed mechanisms with good motion design are no more expensive to manufacture than bad ones, but work much better and longer.

The core of our software and services business is making machines more powerful through good design of mechanisms and motions, faster, quieter and more durable. Over the decades, we gained a lot of practical experience, which we pass on today with workshops and trainings.

If you can only increase the speed of a machine earning your money by 5% by using a few of our tips, a workshop with us has usually been worthwhile. Often, however, we achieve a speed improvement by more than 40% when we optimize machines dynamically!

You benefit permanently from the ideas we share with you. Apply the knowledge to several machines and multiply your success!

All trainings are carried out online.

Appointments can be set freely.

For your special requirements, we also combine topics from various trainings into an individually designed training package.

Contact us!

Generally, we want to answer all your questions as part of our training and seminars.

We like to discuss all topics referring your specific tasks, as far as secrecy permits.

In all trainings, the main focus is on methods and improvements that can be integrated into your existing design practice without much effort and thus give you immediate benefits.

Energy Efficiency

Learn how to make mechanisms and motions energy efficient in a simple way!

Machines should not only be fast, flexible, easy to handle and inexpensive, but also use as little energy as possible during operation. This seminar gives the participants tips and solution suggestions on how to optimize the energy turnover in mechanisms with cams, linkages and servo drives. For example, we show jerk-free motion laws that can deliver 22% less energy than the most favorable motion laws in the popular VDI Guideline 2143, and cams that theoretically shrink the drive torque and thus the power to zero. By clever arrangement of mechanisms and masses and springs, the power to be applied by the drive can usually be reduced to the compensation of the friction and the forming forces on the output, ie the unavoidable minimum.

Content:

• Calculating the drive torque from the power course
• Energy-saving motion beyond the VDI guideline 2143
• Design of power balancing mechanisms
• Power compensation cams
• Evaluation of dynamic designs with joint force and energy diagrams
• Eigenmotion
• Torque compensation with cams or linkages
• Torque compensation with non-circular wheels or indexing gears
• Dynamic design of as compact a servo drive train as possible, in a linear case with constant mass moment of inertia, in linkages with non-linear gear ratio and in smooth or unsteady drive of camshafts
• Overview of VDI Guideline 2149 on Mechanism Dynamics
