His experience guarantees fast, thorough and effective results throughout all phases of the development process, thus enabling companies to achieve their objectives.
Expertise & projects
Precision MechanicsIs the required stiffness met? Are the material stresses within limits? Is there no hidden stick-slip? Does the assembly meet its accuracy when all production tolerances are accounted for?
Drafting SpecificationsA good design must fulfill many specifications, for example specifications concerning mass, stiffness, reproducibility, cost of goods, environmental conditions or heat dissipation. By drawing…
Concept DesignA good concept study gives you insight in the feasibility, cost of goods, design alternatives and the required development time. With the chosen concept you can timely adapt…
QualificationOf course first time right is the goal of a new development. The preliminary phase of concept design, drafting specifications and conducting the required analysis will bring you close…

In a previous article the statistical tolerance stack-up analysis is discussed. It is usually profitable to do a statistical tolerance stack-up analysis instead of a worst-case analysis. A worst-case analysis often leads to low tolerance specifications and therefore...read more
In the article Worst-case Tolerance Stack-up Analysis you read about the worst-case or linear stack-up analysis. In such an analysis it is assumed that all dimensions in the tolerance chain have worst-case deviations form their nominal value. In a statistical analysis...read more
Suppose that you went through your tolerance analysis step plan and made a tolerance chain. The only thing to do now is to add up all tolerances. This seems easy enough but there are a few questions to consider: What to do with asymmetrical tolerances? Do you perform...read more
Tolerances become important as soon as you design an assembly of parts. Of course each dimension must be provided with a tolerance. But in an assembly the tolerances become important because all parts must fit. In this article I tacitly will assume that we are dealing...read more
The flexure hinge is a tried and tested construction element in precision engineering systems. It is created by drilling or spark erosion of two adjacent holes. The positive properties of flexure hinges (free of play and friction) are partly undone by the limited...read more
