Error Budget

Error budgeting in your browser.

Trace error contributions across a kinematic chain — from coordinate system to point of interest. Rank dominant terms before tooling, not after assembly.

PartsFinder

Find the right part. Faster.

AI-assisted parts search and supplier matching for hardware engineers. Pull spec-correct components from a curated index — no more 40 tabs of distributor catalog.

Beta

Flexure Designer

Compliant mechanisms, sized in minutes.

Design leaf, notch, blade, and parallelogram flexures from a target stroke and load. Get stiffness in all six DOF, peak stress, fatigue life, and a parametric CAD export — without leaving the tab.

We'll email you the moment it ships.

Beta

Tolerance Stack-up

Worst-case and RSS, in one pass.

1D and 2D tolerance stack-up with both worst-case and statistical (RSS) results. Identify the contributors that dominate the stack and see the effect of tightening or relaxing each.

Bolted Joints: Axial Stiffness of Clamped Members

A preloaded bolted joint shares load between the bolt and the clamped members like springs in parallel. This article uses photoelasticity to visualize the stress field, then compares the member stiffness from experiment, FEA, and an analytical frustum model.
