# Manufacturing Processes > A reference for manufacturing processes, design-for-manufacturing guidance and engineering charts: 118 process pages across 4 categories, 12 reference charts and 8 process comparisons. Every page has a plain-Markdown twin. Process pages are organized into four families — forming, cutting, joining and finishing. Each page answers how the process works, what it can hold dimensionally, what drives its cost, what volumes it suits, and which processes are genuine alternatives. Reference charts carry the full data table inline with its sources — nothing is gated, paginated or hidden behind a download. Scope: this is a reference site for design and mechanical engineers. It is not a supplier directory, does not quote parts, and does not rank or recommend vendors. Numbers are typical published ranges for process selection, not a substitute for a supplier's own capability statement. ## How to fetch Markdown Two equivalent ways to get any content page as Markdown: 1. **Append `.md`** to any content URL — e.g. `https://manufacturingprocesses.org/charts/sheet-metal-gauge-chart.md` 2. **Send `Accept: text/markdown`** with the original URL — e.g. `curl -H "Accept: text/markdown" https://manufacturingprocesses.org/charts/sheet-metal-gauge-chart` Markdown is available for these route patterns (all others are HTML-only): - `/processes` — the full process index, grouped by category - `/processes/` — category hub with a summary table - `/processes//` — process detail: how it works, design guidelines, tolerances, cost drivers, variants, FAQs - `/charts` — the chart index - `/charts/` — chart detail, with every table rendered as GFM - `/compare` — the comparison index - `/compare/` — a head-to-head comparison and its verdict Calculators under `/calculators/` are interactive tools rather than documents and are **HTML only** — there is no Markdown twin. Each one states its formula, its assumptions and the standard it derives from in the page body, so the HTML is still fully readable without executing anything. Every HTML page also advertises its twin with `` in the ``. A concatenation of every Markdown document is available at `/llms-full.txt`. ## Process categories (4) Index: https://manufacturingprocesses.org/processes.md - [Forming](https://manufacturingprocesses.org/processes/forming.md): 60 processes -

[Injection Molding vs 3D Printing](https://manufacturingprocesses.org/compare/injection-molding-vs-3d-printing.md): Injection molding pays for a steel tool up front and then makes parts for pennies; 3D printing has no tooling cost at all but a unit price that never falls with volume. - [Investment Casting vs Die Casting](https://manufacturingprocesses.org/compare/investment-casting-vs-die-casting.md): Investment casting works in almost any alloy, including steel and superalloys, with modest tooling; die casting is limited to low-melting alloys but is far faster per part once the die exists. - [MIG vs TIG Welding](https://manufacturingprocesses.org/compare/mig-vs-tig-welding.md): MIG feeds a consumable wire continuously and lays metal down fast; TIG uses a non-consumable tungsten electrode with separate filler, trading speed for control and weld appearance. - [Powder Coating vs Paint](https://manufacturingprocesses.org/compare/powder-coating-vs-paint.md): Powder coating bakes a thick, tough, solvent-free film onto conductive parts; wet paint gives thinner films, unlimited color matching, and works on substrates that cannot go in an oven. - [Sand Casting vs Die Casting](https://manufacturingprocesses.org/compare/sand-casting-vs-die-casting.md): Sand casting has almost no tooling cost and no size limit but a rough surface and loose tolerances; die casting inverts every one of those trade-offs. ## Tools and calculators (3) (HTML only) Index: https://manufacturingprocesses.org/calculators - [Bend Allowance Calculator](https://manufacturingprocesses.org/calculators/bend-allowance): Bend allowance, bend deduction and outside setback for a sheet-metal bend, from thickness, bend angle, inside radius and K-factor. Formula: BA = A × (π / 180) × (R + K × T). - [True Position Calculator](https://manufacturingprocesses.org/calculators/true-position): Convert measured X and Y deviations into a diametral true position, with optional MMC bonus tolerance and a pass/fail against your feature control frame. Formula: TP = 2 × √(ΔX² + ΔY²). - [Press Fit Calculator](https://manufacturingprocesses.org/calculators/press-fit): Hole and shaft limits, and the resulting clearance or interference, for a nominal diameter and an ISO 286 hole-basis fit. Formula: C_max = ES − ei. ## Site information (HTML only) - [Home](https://manufacturingprocesses.org/) - [Sitemap index](https://manufacturingprocesses.org/sitemap.xml)
