We spent some time with Carlos Hoefken, CTO & Co-Founder, and asked him questions regarding the Motus CAM and CAM Generator™ software. In the video, Carlos uses the ML100 as an example, but the same CAM concept applies to the ML1000 series. Take a look at the slideshow below that shows the CAM Generator software.
What makes the CAM the critical differentiator of our geared solution, and how do variations of the CAM design impact performance?
Carlos: Precision mechanical geared solutions are complex systems that do not follow simple geometric rules; instead, design complexities and dynamic variables of elasticities, deflections, vibrations, temperature changes, friction, wear, tolerances, and more need to be considered. Even the best simulation tools can’t predict a mechanical gear behavior, so something needs to be flexible enough to bridge the gap between theory and reality.
A CAM gives us the flexibility to find the perfect balance between elasticity, friction, and wear conditions to obtain optimal performance for any given geared solution.
Tell us about your innovative CAM optimization software tool?
Carlos: We developed a proprietary software application to calculate optimal CAM curves. Initially, a CAM is generated under pure geometric terms. The testing results often indicate that minor CAM modifications are required. Initially, we used a very primitive graphic method to calculate the CAM shapes that often took days to create a 3D model and final part. The math complexities involved in designing a solution that is continuous minimizes changes and does not self-intersect drove the need to develop an analytical tool to automate and refine this complex process.
After several attempts, we developed and later patented the CAM Generator™ Motion Algorithm software tool. The new tool enables Motus engineers to create a 3D model and final part in minutes rather than days.
Once the CAM is generated, we test and enter needed modifications into the CAM Generator to calculate a new CAM shape and repeat this process as needed. Usually, it takes 10 to 15 iterations to find the optimal CAM for a given gear design.
“The Motus CAM is the physical equivalent of a software program.”
– Carlos Hoefken, Inventor & Chief Technology Engineer
Does this process expedite the prototype, test, and analysis for custom geared solutions?
Carlos: Yes! The CAM Generator™ software tool enables Motus engineers to develop new designs more quickly, produce new prototypes, test and analyze performance, and make incremental to create perfectly optimized motion and performance.
