Free engineering tools
Pressure-test your program in minutes
Twelve free, no-sign-up tools for product teams — readiness, scope, schedule, cost, tolerances, fasteners, structures, plastics, fits, and process capability. Use them on your own; when you're ready for a real delivery plan, the results are the perfect starting point.
Project Engineering Scope Builder
Select the engineering work packages your project needs and get an estimated effort, duration, and cost range — plus a scope summary you can reuse.
Open the toolProject Management Timeline Estimator
Estimate a realistic concept-to-production schedule with stage gates, tooling, regulatory, and prototype iterations factored in — and a target launch date.
Open the toolAssembly Cost Estimator
Build a quick bill of materials, factor in tooling and assembly time, and see unit cost, pricing, and margin scenarios for your product.
Open the toolBernoulli Equation Calculator
Solve for pressure, velocity, or elevation in fluid systems — with the full equation breakdown shown step by step.
Open the toolCritical Path Calculator
Enter tasks, durations, and dependencies to find your project's critical path, total duration, and the float on every task — full CPM analysis in your browser.
Open the toolTolerance Stack-Up Calculator
Walk your dimension loop and compare worst-case against RSS statistical stack-up — with every contributor ranked so you know which tolerance to tighten first.
Open the toolBolt Torque & Preload Calculator
Pick a bolt size, property class, and friction condition to get target preload and tightening torque in N·m and ft·lb — with the full breakdown shown.
Open the toolBeam Deflection Calculator
Size a cantilever or simply supported beam in seconds — max deflection, bending stress, and moment for rectangular, round, and tube sections in common materials.
Open the toolSnap-Fit Design Calculator
Design a cantilever snap-fit that won't break — check bending strain against the material's allowable, then get deflection force and mating force for your geometry.
Open the toolPress-Fit / Interference Calculator
Turn an interference fit into numbers — contact pressure, assembly force, torque capacity, and hub stress from Lamé thick-wall theory.
Open the toolProcess Capability (Cpk) Calculator
Enter spec limits and process data — or paste raw measurements — to get Cp, Cpk, and estimated PPM out of spec, with a distribution-versus-limits chart.

When you need more than tools
Five ways dmc163 helps teams ship
Senior engineering support, sized to your product, team, and manufacturing realities.
01
Product Development
From early concepts to launch — defining requirements, developing design concepts, and guiding products through validation and release.
02
Project Engineering
Owning the technical execution: design, analysis, DFM, prototypes, and test — turning a concept into a buildable, documented design.
03
Project Management
Schedules, budgets, risk, and cross-functional coordination that keep complex hardware programs moving and on track.
04
Manufacturing Readiness
Design for manufacturing, tooling strategy, supplier coordination, and validation that de-risk the move into volume production.
05
Concept-to-Production Leadership
Fractional engineering leadership across the whole journey — strategy, roadmap, and execution without a full-time hire.
Why teams work with dmc163
Strategic vision, executed in the real world
Strategic and hands-on
I partner with leadership to define product roadmaps, then translate business needs into clear engineering specifications — and stay to execute them.
Global manufacturing experience
My designs are proven with manufacturing sites in China, the UK, Mexico, and Japan — built to work in the real world, not just on screen.
Proven team leadership
I have built and led engineering teams, managed budgets and schedules, and delivered complex products to production on time.
