From solid models and mechanical drawings to automation design and product development, we can provide the help you need!

Clients come to NSI for help in various engineering design services and product development with just an idea, a notion, or even a problem statement in mind. We specialize in bringing technology to life.

NSI focuses on designing and developing products with a passion for inventing creative design solutions, expert mechanical engineering techniques, and patented new technologies and strategies. Product development is a creative activity, but it also requires following a disciplined, systematic approach to guide the obligatory processes to get a new product from an idea to a marketable product.

 

THE PROCESS WE TYPICALLY FOLLOW AT NSI IS BROKEN DOWN INTO THE FOLLOWING PHASES

GEOMETRICAL ANALYSIS

 

NSI design and manufacturing team perform geometrical analysis to study and report the effect of geometric dimensioning and tolerances (GD&T) of components of assemblies. Our team analyzes the impact of GD&T from both design and statistical performance. 

We ensure high-fidelity results by using a cross-validation method utilizing mathematical derivations, advanced computer-aided design tools (CAD), and Finite element analysis to: 

  • Determine the tolerance values leading to worst-case scenarios 
  • Determine the tolerance values in compliance with the statistical capability index of the different manufacturing processes (i.e. RSS method). 
  • Evaluate the magnitude of clearance and interference between the different components using both linear and non-linear stack-up analysis
  • Estimate the contribution significance of GD&T of each component leading to a worst-case or statistical scenario. 
  • Compute the allocated 6 degrees of freedom motion range for each component with an assembly due to designed clearance. 
  • Evaluate the magnitude of induced clearance/interference between the different components in the worst or statical scenario due to sustaining the design and operating conditions of the assembly by coupling a parametric CAD model with Finite Elements Analysis (FEA) (i.e. thermal, static, and dynamic mechanical loadings)
