Free engineering tools

Pressure-test your program in minutes

Eight free, no-sign-up tools for product teams — readiness, scope, schedule, cost, tolerances, fasteners, and fluid calculations. Use them on your own; when you're ready for a real delivery plan, the results are the perfect starting point.

Readiness

Product Development Readiness Checker

Score how ready your product is to move toward production across requirements, design, validation, manufacturing, and program management — and see your biggest gaps.

Open the tool
Scope

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 tool
Timeline

Project 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 tool
Cost

Assembly 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 tool
Calculator

Bernoulli Equation Calculator

Solve for pressure, velocity, or elevation in fluid systems — with the full equation breakdown shown step by step.

Open the tool
Schedule

Critical 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 tool
Tolerances

Tolerance 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 tool
Fasteners

Bolt 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.

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.
