Trust the Experts in Turbomachinery

For over 60 years, we have helped leading global OEMs to improve the performance and manufacturability of their turbomachines.

This is a video of Concepts NREC's optional 3+2 Roughing Module that enables roughing out of impellers using 3-axis algorithms, keeping a constant tool vector. This strategy optimizes the toolpath to provide constant cutting load, making it suitable for high speed machining. This is extremely helpful for large (>0.5 m) diameter impellers and/or hard materials where roughing using the 5-axis strategies is less efficient.

The Corporate Transparency Act In this blog series, I plan to touch on a small variety of legal and compliance-related topics that are directly related to the day-to-day operations of small and large companies, including those in the turbomachinery realm. The series will include topics like confidentiality, the recent FTC attempt to ban non-compete agreements, and export/trade compliance. At the outset of each entry (including this one) I will remind readers that this publication is not legal advice, and it should not be relied upon as such. If you find that this discussion raises some questions for you, I encourage you to seek legal counsel.

Evaluating Manufacturability for Shrouded Impellers
by Ryan Lussier, CAM Software Product Manager
Design engineers are always looking for ways to push performance and efficiency. This can produce geometry which is challenging to machine and one of the first questions the manufacturing team needs to answer is, “Can we make this?” There are many factors at play here, such as machines, tools, processes, material, and the geometry itself, that come together to decide capability and feasibility. And sometimes very subtle changes in geometry can lead to massive improvements in manufacturability.
