Henrik Thorwaldsson – Mechanical Design Engineer focused on mechanical design, tolerance analysis and engineering automation.
Fits and tolerance calculators for mechanical design. ISO 286 fits, tolerance stack-ups, MMC bonus tolerance, and process capability, with plain-language results.
Desktop app for 1D mechanical tolerance stack-up analysis
Tolerance stack-up and process capability analysis with worst-case, RSS and Monte Carlo simulation.
Using the Python programming language, this analysis tested seven hypotheses across three phases: whether AI, BCT, and BDA relate to, individually predict, and jointly predict the perceived effectiveness of Forensic Fraud Investigation (FFI). Pearson correlation, simple and multiple linear regressions were used, with OLS assumption checks reported.
Open-source analog-AI circuit research twin with differential conductance encoding, managed ngspice, tolerance analysis, and reproducible evidence.
Simple Monte-Carlo library for tolerance analysis in engineering applications
Tolerance analysis pipeline for a precision optical sensor fixture, using worst-case/RSS analysis, seeded Monte Carlo simulation, sensitivity analysis, Cp/Cpk capability, DOE, and intervention studies.
Exact offline allocation of finite shim stock with worst-case tolerance proof
